C23E8784FFD8FFAC5FA79E992E474C76.taxon	discussion	Comments. Aphalara Foerster, 1848, consists of over 40 Holarctic species, many of which develop on Polygonaceae (Burckhardt and Lauterer 1997 a; Ouvrard 2020). Species often are difficult to identify, as morphological differences between species are small, and intraspecific variation is pronounced. Also host plant ranges sometimes overlap. Unlike the West Palearctic Aphalara species that are fairly well-studied (Ossiannilsson 1992; Burckhardt and Lauterer 1997 a), the North American ones are poorly known. The only comprehensive paper (Caldwell 1937) is based on limited material with species descriptions that are not diagnostic. Several important characters are not described, such as structures on the head, the surface spinules on the forewings or the aedeagus of adults, as well as the immatures. A comparison with material that was studied by J. S. Caldwell suggests that his drawings of the paramere were not made from a strict lateral view and are, hence, difficult to interpret. A slightly more detailed description of A. persicaria of both adults and immatures was provided by Caldwell (1938 a). Currently, 13 species and three varieties are known from the Nearctic region (Hodkinson 1988). Aphalara persicaria is similar to A. nubifera Patch, 1912, and A. simila Caldwell, 1937, in the surface spinules on the forewings that are arranged in squares or rhombes; in all other described Nearctic species the surface spinules form irregular transverse rows. Aphalara persicaria differs from A. nubifera in the unpatterned forewings (rather than with an indistinct brown transverse band in apical third) that are slightly narrower (forewing length / width ratio in A. persicaria 2.5 – 2.7, in A. nubifera 2.2 – 2.3), in the thumb-like process of the paramere that is close to the apex (rather than in apical quarter), in the caudally strongly expanded circumanal ring of the female (rather than with only 3 – 4 cell rows) and in the host association (Persicaria spp. versus Descurainia pinnata (Walter) Britton [Brassicaceae]). From A. simila it differs in the slightly finer surface spinules of the forewing membrane and the caudally strongly expanded circumanal ring of the female, which consists of only two rows in A. simila. Aphalara persicaria currently is known from Cuba and Mexico as well as the eastern and midwestern USA, whereas the other two species have been reported from the western USA and Mexico. The report of A. nubifera var. reducta Caldwell, 1937, from Maine (Caldwell 1937; Hodkinson 1988) is doubtful. Caldwell (1937) described this variety based on a single specimen: Holotype female in the Herbert Osborne collection, Ohio State University, with following data: “ Me. Ag. Exp. Sta., VI – 27 – 1916. ” This suggests that the specimen was donated by Edith M. Patch who worked for the Maine Agricultural Experiment Station in Orono, ME, and is possibly part of the type series of A. nubifera from Ft. Collins, CO. Caldwell (1937) erected A. persicaria var. cubana Caldwell, 1937 for specimens from Cuba. He indicated that they appear smaller and darker than A. persicaria and possess more obliquely truncate parameres and a less curved female proctiger. The examination of type material of A. persicaria var. cubana showed that these differences are within the variation of A. persicaria from Mexico and the USA (FL, MD, MI, OH, VA). In type material of A. persicaria var. cubana the paramere is slightly rounded apically (Fig. 28, 30), and the apical inflation of the distal segment of the aedeagus bears a short apical hook (Fig. 29, 31), whereas in types of A. persicaria the paramere has subparallel margins and is truncate apically (Fig. 39), and the apical inflation of the distal segment of the aedeagus bears a long apical hook (Fig. 40). Some specimens at hand from Florida bear a characteristic “ cubana - type ” paramere and a “ persicaria - type ” aedeagus (Fig. 35, 36) or vice versa (Fig. 37, 38). In other examined specimens these structures were intermediate between these two types (Fig. 33, 34, 41, 42). Immatures from FL and OH do not significantly differ from each other and correspond to Caldwell’s (1938 a) description. We conclude that A. persicaria var. cubana is a synonym of A. persicaria, confirming Hodkinson’s (1988) synonymy. Craspedolepta Enderlein, 1921 Comments. Craspedolepta is a large Holarctic genus with over 150 described species, of which about two thirds occur in the Palearctic realm, one third in the Nearctic and less than a handful in both. Most of the species develop on Asteraceae (Ouvrard 2020). Many Central and Northern European species, generally well diagnosed, are monophagous (Ossiannilsson 1992; Lauterer and Burckhardt 2004; Burckhardt and Lauterer 2009). Similar, narrow host ranges also can be expected in other regions, but these patterns are blurred by the lack of a sound taxonomic base or by an inadequate concept of “ host ” (or by both) (Lauterer and Burckhardt 2004; Burckhardt et al. 2014). The most recent treatment of Nearctic Craspedolepta species is the monograph by Journet and Vickery (1979), listing four species from Florida: C. furcata (Caldwell, 1936), C. nota Journet and Vickery, 1979, C. numerica (Caldwell, 1941) and C. parvula Journet and Vickery, 1979. All four records are problematic, as Journet and Vickery’s (1979) descriptions are not diagnostic, and at least some of their “ species ” contain mixes of multiple species. Moreover, their host information does not help to define the species, as they did not indicate which records are confirmed by the presence of immatures. The use of the terms “ primary ” and “ secondary ” host adds to the confusion as these concepts are not defined by the authors. In the material from Florida at hand, we identified four species, viz. C. bifida (Caldwell, 1936), C. euthamiae spec. nov., C. flavida (Caldwell, 1938) and C. furcata. We did not see specimens of C. parvula from Florida. According to Journet and Vickery’s (1979) description, the species keys out in our key with C. flavida from which it differs in the smaller size. More material, including adults of both sexes and immatures with confirmed host information, is needed to investigate and fully understand the taxonomy of Craspedolepta in Florida.	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FFDCFFB05FA79904288C4E6C.taxon	diagnosis	Diagnosis. Differs from the morphologically similar C. furcata in the apex of the aedeagus and the female terminalia. Apex of distal segment of aedeagus hardly convex (Fig. 62) rather than distinctly convex as in C. furcata (Fig. 63 – 65). Female proctiger, in profile, straighter dorsally with slightly shorter distal process that is hardly inflated apically (Fig. 66), compared to C. furcata where the proctiger is more undulated dorsally with a longer, apically slightly inflated distal process (Fig. 69). Dorsal and ventral valvulae are slightly more curved, with apically weakly serrate ventral valvulae in C. bifida (Fig. 67) rather than only weakly curved valvulae, lacking ventral serration as in C. furcata (Fig. 70).	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FFDCFFB05FA79904288C4E6C.taxon	discussion	Comments. Caldwell (1936) described C. bifida from three females from Miami, FL. He separated the species from the similar C. furcata by the proportionally shorter vertex, the shallower “ notch at end of median line ” and the less distinct foveal impressions (Fig. 44: C. bifida; Fig. 45: C. furcata). Further he suggested that in C. bifida the build is less robust, the thorax less arched (Fig. 46: C. bifida; Fig. 47: C. furcata) and the forewings are very flaveous with a longer and narrower cell cu 1. The female terminalia of C. bifida (Fig. 66) are said to differ from those of C. furcata (Fig. 69) in the shorter and straighter proctiger, the subgenital plate with a deeper notch at apex (Fig. 68: C. bifida; Fig. 71: C. furcata) and the entire terminalia being “ more thickly beset with small setae ”. Journet and Vickery (1979) discarded all these differences except for the body size that they interpreted as clinal variation. They listed Aphalara bifida as a junior synonym of Craspedolepta furcata but stated under comments: “ Upon ... the variability of the remaining characters used by Caldwell (1936) in discriminating between his species, relegation of A. bifida to the junior synonymy under C. constricta [sic] (Caldwell 1936) is justified. ” This is probably an error and should be C. furcata. We agree with Journet and Vickery (1979) that the characters on the head (Fig. 44, 45), thorax (Fig. 46, 47) and forewings, the setosity of the female terminalia (Fig. 66, 69) and the apical notch of the female subgenital plate (Fig. 68, 71) do not significantly differ between C. bifida and C. furcata. The differences in the aedeagus, female proctiger and valvulae are, however, significant enough to consider C. bifida as a good species. Specimens of C. bifida have been collected in January and October, those of C. furcata from Florida in July and October (USNM data).	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

USA: Florida: Alachua, Brevard, DeSoto, Highlands, Indian River, Lake, Martin, Miami-Dade, Nassau, Okeechobee, Orange, Osceola, Pasco, Pinellas, St. Lucie, Volusia counties. The species was identified first in Florida between November 2002 and February 2003 in several Florida counties by DPI inspector Kenneth Hibbard. Some specimens of the new species collected during this period are from additional localities but were not restudied for the description. Thus, they are not included in the data above. These localities (alphabetical by county) include Palm Bay (Brevard County; FSCA # E 2002 - 5849), Arcadia (DeSoto County; FSCA # E 2004 - 7522), Lake Placid (Highlands County; FSCA # E 2003 - 23), Ft.

In the Atlas of Florida Plants (Wunderlin et al. 2020) Euthamia caroliniana is considered a valid species; in the World Flora Online (WFO 2020), however, it is a synonym of E. graminifolia. All the records from Florida are from E. caroliniana. Derivation of name. Named after its host genus Euthamia.	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FFC0FFB55FA79E132E0C4E9E.taxon	discussion	Comments. Adults of Craspedolepta euthamiae spec. nov. differ from all other similar North American species, i. e. species with spotted forewings, bearing surface spinules usually forming a hexagonal pattern consisting of a single row of spinules, with a lamellar paramere widening towards the apex, and with distal segment of the aedeagus strongly expanded apically with a small anterior hook, as follows. Craspedolepta caudata (Crawford, 1911), C. minuta (Caldwell, 1938) and C. numerica (Caldwell, 1941) have a broader, slightly more curved paramere. Craspedolepta fumida (Caldwell, 1938), C. macula Journet and Vickery, 1979, C. maculimagna Journet and Vickery, 1979, C. nota Journet and Vickery, 1979, and C. scurra Journet and Vickery, 1979, have female terminalia that are longer, with the dorsal margin of the proctiger distinctly undulate. The female terminalia of C. constricta (Caldwell, 1936) also are longer, but the dorsal margin of the proctiger is distinctly concave. Craspedolepta smithsoniana Klimaszeski, 1979, differs in the much smaller apical dilatation of the distal segment of the aedeagus and the much shorter end tube of the ductus ejaculatorius. In C. parvula Journet and Vickery, 1979, and C. vulgaris Journet and Vickery, 1979, the paramere is similar but the rugose microscultpture on the inner face is much more restricted and the sclerotized end tube of the ductus ejaculatorius is only about half as long as the distal segment of the aedeagus. Craspdolepta ochracea (Provancher, 1872) has similar parameres and aedeagus but lacks dark spots in the forewings, has a shorter end tube of the ductus ejaculatorius, and longer female terminalia. Virtually nothing is known about the immatures of the North American Craspedolepta species. Descriptions exists only for C. nebulosa (Zetterstedt, 1840) and C. subpunctata (Foerster, 1848), two Holarctic species associated with Epilobium angustifolium (Onagraceae) (Ossiannilsson 1992). Both species share the 3 - segmented antennae with C. euthamiae but differ in the circumanal ring that consists of several rows of pores. Craspedolepta numerica was reported “ from southwestern United States and Mexico, though some specimens from Florida seem to fall within this species ” (Journet and Vickery 1979). From Florida, they mentioned specimens from Garnett, Mascotte and Hilliard which we examined (USNM). The material from Garnett belongs to C. numerica of which we have examined the types (USNM) (Fig. 76 – 78, 81), however, Garnett is not in Florida but is in Kansas. The specimens from Mascotte and Hilliard belong to C. euthamiae and constitute a part of the type series. Craspedolepta euthamiae and C. numerica are similar in body size, forewing shape with spotted membrane (Fig. 48), the surface spinules forming hexagonal pattern consisting of a single row of spinules (Fig. 49), the shape of the aedeagus (Fig. 75, 78) and the female terminalia (Fig. 79, 81). They clearly differ in the shape of the paramere and the presence or absence of tubercular microsculpture on the inner surface (Fig. 73, 74 versus 77). Craspedolepta nota was described from 12 adult specimens from Canada (Alberta, Manitoba) and the USA (FL, KS). Journet and Vickery (1979) stated that the separation from C. caudata (Crawford, 1911), C. macula Journet and Vickery, 1979, and C. numerica is “ problematic ”. We suspect that Journet and Vickery’s (1979) C. nota is a species mix, and the specimens from Florida belong to C. euthamiae spec. nov.	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

The forewings are yellow and slightly coriaceous, with a heavy black partial stripe on the leading edge. Genal processes are undeveloped, and antennae are short. This species belongs to a small Neotropical genus with another three described and several undescribed species that all are monophagous on Nectandra species. The immatures of L. brevicephala (Fig. 88) differ from those of L. eucosma Burckhardt and Queiroz, 2013, and L. lautereri Burckhardt and Queiroz, 2013, in the smooth body surface that is densely covered in elongate tubercles bearing a lanceolate seta each in the other two species (Burckhardt and Queiroz 2013).	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FFC7FFB65FA79D0F2ED34946.taxon	discussion	Comments. Species of Pachypsylla are mostly gall-inducers on Celtis L. (Cannabaceae) in North America. The genus is a taxonomic chaos, and much of the published distributional data should be treated with caution. Several species were described based on galls only (Riley 1890), which were incorrectly considered nomina nuda by Tuthill (1943). Tuthill (1943) also concluded, for the lack of finding morphological differences between the adults emerged from different galls on the leaves of Celtis occidentalis L., that the gall shape is variable induced by the single species Pachypsylla celtidismamma (Riley, 1875). Hodkinson (1988) listed the following of Riley’s names as synonyms of Pachypsylla celtidismamma: Pachypsylla celtidisasterisca Riley, 1890, P. celtidiscucurbita Riley, 1890, P. celtidisglobula Riley, 1890, P. celtidispubescens Riley, 1890, and P. celtidisumbilicus Riley, 1890. Yang and Mitter (1994) studied Pachypsylla galls and concluded that P. celtidismamma is a complex of cryptic species. Thomas (2011) reviewed the nomenclatorial aspects and recognized 14 nominal species. At least one serious but unpublished attempt has been made to sort out the Florida species, based on notes in DPI files from John E. Porter, United States Department of Health, Education, and Welfare, Miami, FL. Files include a letter to Frank W. Mead written in 1962. Comprehensive biological, morphological and molecular studies are needed to determine accurate species assignments. All species seem to produce one generation per year in Florida. Hodkinson (1988) does not list any species from Florida and the following list of species present in Florida is tentative. It is based on specimens in the FSCA and NHMB provisionally identified by us, mostly using the key of Tuthill (1943). The taxonomy of Pachypsylla is in need of revision, which is outside the scope of this paper.	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FFC9FFB85FA5982929BB49FA.taxon	diagnosis	Diagnosis. Tetragonocephala flava can be recognized by the lerps on Celtis leaves (Fig. 91). Lerps are clam shell shaped and open on the side. They are attached to the undersides of the leaves, often near forks in the leaf veins. Adults resemble the more common Pachypsylla species, but they are pale and have six dark spots on the mesonotum and one at the posterior tip of the scutellum (Fig. 90).	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FFC9FFB85FA5982929BB49FA.taxon	distribution	Distribution. Tetragonocephala flava was described from the southern tip of Texas and is known from Mexico (Ouvrard 2020). Its long presence in Florida, lack of serious damage to hosts, and the presence of a native parasite suggests that it is native to Florida. However, it possibly is adventive in Louisiana, where there was an outbreak that caused serious damage to the trees (Solomon et al. 1997). Florida distribution information. Tetragonocephala flava was recognized in Florida for the first time in April 1997 on Celtis laevigata Willd. in Oak Hill (Volusia County) (FSCA # E 1997 - 1214) (Halbert 1997 b). Collectors were Avas Hamon, Ru Nguyen, Kenneth Hibbard, and L. J. Chambliss. Previously unrecognized specimens from Florida in the FSCA go back to 1957, when a specimen was collected at Snapper Creek Boy Scout Camp (Miami- Dade County) by sweeping Celtis. The exact date is unclear on the label, and no collector is mentioned. We have records, but no specimens, from Jacksonville (Duval County) collected 15. viii. 1997 (FSCA # E 1997 - 3281), Lake Jem (Lake County) collected 28. vii. 1997 (FSCA # E 1997 - 3438). The most recent collection was in Ft. Myers (Lee County) in June 2005, consisting of 6 empty lerps (FSCA # E 2005 - 2972).	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FFC9FFB85FA5982929BB49FA.taxon	discussion	Comments. In Louisiana, major dieback of stands of C. laevigata was attributed to high populations of T. flava (Solomon et al. 1997). In Florida, no similar destruction of trees was observed, possibly because of a native parasite, Aprostocetus gelastus (Burks, 1943) (Eulophidae), that controlled psyllid populations (Halbert 1997 a). More recently, the Asian aphid, Shivaphis celti Das, 1918, (Aphididae) has become established on C. laevigata in Florida (Halbert et al. 2000). This aphid is very abundant and may prevent build-up of populations of T. flava, which, based on submitted samples, has been rare since the establishment of S. celti in Florida.

Now, the species occurs on all continents except Antarctica. Details on the distribution and the damage inflicted to Eucalyptus are provided by Queiroz et al. (2018). Blastopsylla occidentalis was found for the first time in Florida in the Orlando (Orange County) area by Susan Halbert and DPI inspectors Barbara Wilder and Anthony Capitano on Eucalyptus at an amusement park in April 2001 (FSCA # E 2001 - 1596). More specimens were found in another amusement park in the Orlando area in May 2001 (FSCA # E 2001 - 1989), and the identification was confirmed by Dr. Ray Gill, CDFA (Halbert 2001 b). In June 2002, two specimens were collected in the suction trap in Miami (Miami-Dade County) (FSCA # E 2002 - 4697). The presence of the psyllid was confirmed in Miami-Dade County in 2002 (FSCA # s E 2002, 4697, E 2003 - 2766, 3199) when colonies were found on Eucalyptus in Miami. The psyllid also was found in Sarasota (Sarasota County) on Eucalyptus by Bertila Gomez and Julieta Brambila in June 2003 (FSCA # E 2003 - 2302). Since then, there have been numerous detections, particularly in suction traps.	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

Boreioglycaspis melaleucae is one of only two psyllids in Florida that have long genal processes that are 0.8 times the length of the vertex or longer (Fig. 93). Boreioglycaspis melaleucae can be separated from Glycaspis brimblecombei by its shorter antennae, which are less than twice head width, and by the forewing venation: the branching of vein M of B. melaleucae is distal to the point at which Cu 1 a intersects the edge of the wing (Wineriter and Halbert 2002). Adults and immatures of Boreioglycaspis melaleucae colonies in the laboratory were tan in color (see photographs in Wineriter and Halbert 2002) but became bright orange after release in the field (Fig. 93, 94).	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FFCBFFBD5FA799602E184C54.taxon	discussion	Comments. Boreioglycaspis melaleucae Moore, an Australian native species, was introduced deliberately to control Melaleuca quinquenervia (Cav.) S. T. Blake (Myrtaceae), a noxious weed in the Florida Everglades. Since the release in April 2002, the psyllids, specific to M. quinquenervia, have established large populations in several South Florida counties including Broward (FSCA # E 2003 - 1926, 2067, 2262, 2263), Lee (FSCA # E 2003 - 2208, 3609, E 2004 - 433), Collier (FSCA # E 2003 - 3034) and Miami-Dade (FSCA # E 2003 - 6018, 6356, E 2004 - 369). There have been suction trap collections in Miami (Miami-Dade County), beginning in October 2003 (FSCA # E 2003 - 5336). The suction trap in Immokalee (Collier County) also began collecting specimens in October 2003 (FSCA # E 2003 - 5512, 5611). The suction traps in Winter Haven (Polk County) began collecting B. melaleucae in 2004, followed by consistent collections with numbers over 100 per sample sometimes occurring in spring and summer months. At least 2,500 specimens were collected in the Winter Haven suction traps. In Immokalee (Collier County), collections occurred in the spring (mostly March – June) and in some years there were collections in the fall and winter (October – January). Since 2013, numbers of the B. melaleucae population in Florida have diminished markedly for unknown reasons. * Ctenarytaina Ferris and Klyver, 1932	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FFCDFFBF5FA799AF2FFA4D53.taxon	discussion	Comments. Glycaspis brimblecombei is the most serious pest of Eucalyptus among the eucalypt psyllids (Brennan and Gill 1999; Halbert et al. 2001; Queiroz et al. 2013). The lerps and the honeydew secreted by the psyllids are sticky, and infested leaves become coated with sticky residue from the psyllids and with sooty mold. Severe defoliation and death of trees can occur. The infestations cause a troublesome sticky mess, particularly in urban sites. The humid climate in Florida appears not to be ideal for this species, and it is found mostly in the dry spring months. At first, populations were numerous in the spring but subsided during our subtropical summers. Currently, numbers apparently are very low, but there are occasional suction trap collections in Immokalee (Collier County). Glycaspis brimblecombei was found to be established on Eucalyptus in Florida at an amusement park in the Orlando (Orange County) area in April 2001 by DPI inspectors Barbara Wilder and Amanda Melco (FSCA # E 2001 - 1296) (Halbert 2001 a). Subsequent surveys indicated the infestation was fairly localized and heaviest surrounding a dumpster in a holding area for new landscape plants. The likely source of the infestation was imported Eucalyptus trees from California. We have one earlier record of an interception on cut flowers from California found in April 2000 in Thonotosassa (Hillsborough County) (FSCA # E 2000 - 1136). During the spring and summer of 2000, the infestation of G. brimblecombei spread to surrounding communities within Orange County (Oakland: FSCA # E 2001 - 1843; Apopka: (FSCA # s E 2001 - 2109, 2110, 3532); Taft: (FSCA # E 2001 - 2541). In June 2003, the new pest was detected in Sarasota (Sarasota County) in Southwest Florida by Bertila Gomez and Julieta Brambila (FSCA # E 2003 - 2302). This species has become established on Eucalyptus in the central Florida peninsula. Glycaspis brimblecombei also was detected in Mexico for the first time in Aguascalientes in November 2001 by Bertila Gomez (FSCA # E 2002 - 55). Glycaspis brimblecombei also was found in Matão, São Paulo, Brazil in suction trap collections beginning in 2006 (FSCA # E 2007 - 701).

The female from Key West is similar to the female holotype in body size and color; in the shape of the genal processes which are about two thirds of the vertex length; in the forewing shape which is ovoid with an indistinctly angular apex; with surface spinules on the wing membrane in all cells leaving moderately broad spinule-free stripes along the veins; in the female terminalia which are cuneate with proctiger bearing a rim around the circumanal ring, dorsal outline of proctiger almost straight, very weakly sinuous; subgenital plate pointed, broken in female from Key West. Antennae missing in holotype. The holotype differs from the other female in the larger cell cu 2 and the shorter vein Cu (about as long as vein Cu 1 a), longer than vein Cu 1 a in the Key West specimen. More material and host plant information are necessary to assess the identity of C. arcuata and the identity of the Key West specimen.	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FFF1FF805FA79AF02E654D61.taxon	discussion	Comments. Immatures secrete white fluffy wax (Fig. 99). The species is not likely to be of economic significance in Florida, although Cedrela plants are considered to be high value nursery stock. The species has been found only in south Florida where the host plants occur. After the first detection, no specimens were found for several years, leading us to suspect that the population had been eradicated; however, a small outbreak occurred in Miami- Dade County in 2016, accompanied by suction trap collections and infested plants.

Between 2001 and 2014, there were 10 interceptions of this species at US ports of entry (Smith-Pardo 2014). Only one incident involved the family Malvaceae, in which reported hosts can be found. One interception was on lettuce (Lactuca sativa L.), a common plant for hitchhikers (DPI unpublished data), and five were found on Lamiaceae Martinov. Most interceptions were from Mexico, but one was from Ecuador, indicating that the species probably is established there.	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FFF3FF835FA79E4E2E5C4939.taxon	discussion	Comments. Much of the range extension of this pest in Florida can be attributed to movement of ornamental Murraya paniculata (L.) Jack (Rutaceae) plants through discount and other retail sales (Halbert et al. 2003, 2012). As a direct pest, D. citri is not particularly serious, although new growth of young citrus trees can be damaged badly if populations are high. In much of the citrus production area of the world, including Florida, D. citri causes severe damage to citrus through transmission of the pathogens that cause citrus greening disease (Halbert and Manjunath 2004). Diaphorina citri is the only citrus psyllid present in the New World, and it is distinct from the other species that colonize citrus around the world (Halbert and Manjunath 2004). In the Old World, Diaphorina has almost 80 described and at least as many undescribed species (Ouvrard 2020; Burckhardt, unpublished information) whose identification can be tricky and needs some experience.

The immatures are submerged in honeydew (Fig. 115, 116) as this is characteristic for other Katacephala and at least some Notophorina Burckhardt, 1987, species (Burckhardt, unpublished observation). Derivation of name. This species is dedicated to Susan Wineriter Wright, who worked for many years for the USDA invasive weed biological control program. This species of Katacephala was discovered in research plots maintained by the USDA in Ft. Lauderdale (Broward County). Researchers, under direction of Susan Wineriter Wright, were growing several rare and endangered Myrtaceae to see if B. melaleucae, released for control of M. quinquenervia, would colonize the native plants. One of the routine inspections by Kirk C. Tonkel, AmeriCorps Volunteer, revealed a population of psyllids on C. pallens (FSCA # E 2003 - 2021). Subsequent collections were made from the same location by Robin Johnson in July 2003 and January 2004 (FSCA # s E 2003 - 4102, E 2004 - 1105).	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FFF2FF895FA799F529954DD3.taxon	discussion	Comments. Katacephala Crawford is a small New World genus comprised of eight described species (Hodkinson 1991 b; Burckhardt 1994). Katacephala wineriterae resembles K. cinctata Hodkinson, 1991, from Mexico in the head, which is weakly inclined from the longitudinal body axis and bearing relatively large eyes and lobular genal processes, the subrhomboidal forewings with ill-defined costal break, slender C + Sc, basally curved Cu 1 a and characteristic pattern, as well as the six apical metatibial spurs. Katacephala wineriterae differs from K. cinctata as follows: genal processes more angular laterally (in K. cinctata more rounded), forewing vein C + Sc strongly bent in apical third (in K. cinctata evenly curved), the relatively longer forewings (2.1 – 2.3 versus 1.9 times as long as broad), the narrower and shorter pterostigma and the relatively longer female subgenital plate apically almost reaching tip of proctiger. Differences in the male terminalia cannot be evaluated as the male of K. cinctata is unknown. Katacephala wineriterae differs from the other three Katacephala spp. recorded from Florida in the weakly inclined head, the lobular genal processes, which are conical in the other species, the slender vein C + Sc and the basally strongly curved Cu 1 a. Immatures of Katacephala are currently known only from one species, i. e. Katacephala longiramis (Burckhardt, 1987). Immatures of Katacephala wineriterae differ from those of K. longiramis in the presence of sectasetae and the absence of a circumanal ring (terminal and consisting of multiple rows of pores in K. longiramis).

C23E8784FFF9FF8D5FA79B5C2E494C8B.taxon	discussion	Comments. Pseudophacopteron is a pantropical genus previously not recorded from North America. In the Neotropics, the genus is known from five species from Panama (Brown and Hodkinson 1988) and two species from Brazil (Malenovský et al. 2015). Pseudophacopteron gumbolimbo resembles P. antennatum Brown and Hodkinson, 1988, in the forewing pattern and the shape of the paramere and the female terminalia but differs in the subequal terminal antennal setae, the apically more angular forewings, and in the shape of the apical dilation of the aedeagus, which is relatively narrower and only slightly curved ventrally, hardly hooked. The species probably is native to Florida. Immatures are found on undersides of new leaves, causing no damage other than an occasional indistinct yellow spot. Adults have been collected in the suction trap in Miami- Dade County in all months except August and September.

This undescribed species of Acizzia was discovered in Miami by Florida Department of Agriculture and Consumer Services, Division of Plant Industry (DPI) inspector Olga Garcia. The first specimens were found as stray adults on Eucalyptus. Subsequent specimens were found in suction traps in Miami-Dade and Collier counties. DPI inspector Scott Krueger solved the host association when he discovered colonies in Collier County on Acacia auriculiformis, a native Australian plant, suggesting that the psyllid also originates from Australia. This species has become numerous in Florida. Based on suction trap collections, flight activity occurs in spring and fall.

Heteropsylla flexuosa was found established at Port Everglades, FL in late January 2013 by DPI inspector Stephen Beidler on Acacia farnesiana (FSCA # E 2013 - 522). This species is similar to Heteropsylla mimosae, which has been in Florida since 1983 (see below).

It was thought that Heteropsylla fusca was reported in Florida (Muddiman et al. 1992) based on a specimen at the United States National Museum (USNM) from “ Arrocera, Florida, ” collected in April 1957 by “ J. Acuna. ” However, this location is in Florida, Camaguey Province, Cuba. Julian Acuña, who worked in Cuba, is the collector, and “ Arrocera ” probably refers to a rice field (Robert E. Woodruff, FSCA, personal communication, 2011). Thus, ours is the first Florida (USA) record. Evidently, the species is native to the Caribbean but has become established in the Pacific islands and California.	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FFE2FF925FA79FFD28F94A1B.taxon	discussion	Comments. Muddiman et al. (1992) separated H. huasachae from H. propinqua by the straighter posterior margin of the inner lobe of the paramere, the more pronounced ridge on the female subgenital plate, and the frons with an anterior groove in the middle of the immature in H. propinqua. These authors admitted that there are no significant differences between the two taxa in their distributions nor host ranges. We are unable to attribute the material from Florida at hand to either of the two species with certitude, and to corroborate morphological differences between the two species based on the study of the material from several countries (see above). The difference in the paramere shape is mostly due to the angle of observation. In several larger samples, assumed to constitute a single population each, we found females with more or less shallow subgenital plate with more or less pronounced subapical ridge. The presence of an anterior groove on the frons of immatures appears to be due to the age of a specimen (more or less sclerotized; pharate adult development inside immature) and, mostly, the type of preservation (slide mounted or in ethanol). For these reasons we consider H. propinqua a junior synonym of H. huasachae and formally synonymize the two species. Specimens of H. huasachae in the FSCA go back to May 1955, when specimens were collected by H. Burnett in Vero Beach on “ Morongia uncinota. ” This plant name, even after “ uncinota ” is corrected to “ uncinata ” is not valid (Barneby 1995). It is not clear what the host was. Other specimens have been collected from Acacia and Albizia in Florida. It is common on Albizia.	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

The more recent collections indicate that this species is still around and possibly moving in nursery trade. Prior to its discovery in Florida, M. albalineata was known only from Mexico, Nicaragua, El Salvador, and Venezuela (Hodkinson and White 1981). The Florida host is Senna, on which it is a pest, causing severe leaf curling and distortion (Fig. 148). A single primary parasite, Psyllaephagus sp. (Hymenoptera: Encyrtidae), was obtained from the colony collected on 2. x. 2002 from the infested nursery. There have been a few subsequent collections, but the species has not become a widespread pest, even though the plant is a popular ornamental.	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FFE5FF945FA7983629AF4B6D.taxon	discussion	Comments. Mitrapsylla cubana has been known from Florida for a long time, but it is rarely collected except in traps. At the USNM, there are specimens from “ Arrocera, Florida ” (no host information) collected on “ 17. iv. 1957, J. Acuna. ” This location actually is in Cuba (see note under Heteropsylla fusca for details). Thus, the first confirmed USA record is represented by an FSCA specimen from Archbold Biological Station (Highlands County) collected by H. V. Weems and Thomas A. Webber in an insect flight trap on 5. xi. 1979. The USNM has specimens that were collected from Ft. Pierce, FL, by A. E. Kretschmer in March 1980 from Desmodium heterocarpon (L.) DC. (Fabaceae) in a greenhouse. Stray adults were collected twice on Euthamia graminifolia by DPI inspector Kenneth L. Hibbard in Port St. Lucie on 8. xii. 2003 (FSCA # E 2003 - 6307) and in Lorida (Highlands County) on 19. xi. 2002 (FSCA # E 2002 - 5702). This species was described from Cuba and occurs in Brazil, Mexico, Panama and Puerto Rico, where the host plants are Desmodium spp. (Brown and Hodkinson 1988). We have suction trap collected specimens from nearly all the traps we have utilized. Judging by the number of trap collections over the years, M. cubana is common in Florida, but it is collected rarely on its host plants. Based on suction trap collections, flight activity occurs mostly, if not exclusively, in winter months; however, the two early host-associated collections occurred in March and April. Even though this psyllid has been known for decades in Florida, it was never reported formally, probably because “ Arrocera, Florida ” was assumed to be in the USA.

Bactericera is a predominantly Holarctic genus with over 160 described species (Ouvrard 2020). Its known host range is unusually wide, covering 13 families and 11 orders of eudicots and one family and one order of monocots (Burckhardt and Lauterer 1997 b). Salicaceae hosts the largest number of Bactericera species (over 40 spp.), followed by Compositae (17 spp.) and Solanaceae (6 spp.) (Burckhardt and Lauterer 1997 b). Not included in these counts are five polyphagous Bactericera species. Bactericera is a taxonomically difficult genus. Particularly problematic in this respect are the Nearctic species associated with Salix. When trying to identify and name the species on Salix caroliniana Michx. from Florida it became evident that this group is in a taxonomic chaos. For putting our conclusions regarding the Florida species in a general context we provide a list of all valid Nearctic Bactericera species associated with Salix with synonyms and homonyms (Appendix 1).	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

Specimens (currently at the USNM) were found on a “ halophytic shrub ” at St. Marks Wildlife Refuge, Wakulla Beach (Wakulla County), by J. Ray in June 1975. More specimens were found on Lycium carolinianum Walter (Solanaceae) in Cocoa Beach (Brevard County) by R. E. Burns on 29. ii. 1984. More recently, specimens were found by DPI inspector Thomas Turner on Lycium carolinianum at Weedon Island State Park (Pinellas County) (FSCA # s E 2002 - 152, 192, 224, 503, 522, 1020). The same inspector also collected specimens at Hammock Park near Dunedin (Pinellas County) (FSCA # E 2002 - 253). There were other collections from Miami-Dade County (E 2008 - 8234) and Levy County (E 2014 - 210). This species can be cultured fairly easily on L. carolinianum and sometimes on Lycium barbarum L. Bactericera dorsalis was known previously from the western USA, but not from Florida. However, the plant is native, so we suspect that B. dorsalis is also native to Florida. It usually occurs in very low numbers on plants just above the reach of the tides.

Reported from USA: IA (Mally 1894, as Trioza salicis), CO, LA, IL (Crawford 1910 b, as Trioza nigra), OR (Crawford 1911 a, as Trioza minuta similis). – Florida: Alachua, Collier, Hillsborough, Marion, Miami- Dade, Polk, St. Lucie counties. This species was discovered in Florida in suction trap samples. The first specimen was collected in the Miami-Dade County trap (FSCA # E 2007 - 8729). In 2010 (FSCA # E 2010 - 4570), a specimen was collected in a Collier County suction trap. The psyllid has become much more common in the Collier County traps than in Miami-Dade County. A single specimen was collected in a Polk County trap in 2012 (FSCA # E 2012 - 1758). Suspecting that this psyllid was on willows, we surveyed by sweeping willows near the Immokalee (Collier County) suction trap. Several adults were found by sweeping willows in both Collier (FSCA # E 2013 - 6535, E 2014 - 2837, 2840) and Hillsborough (FSCA # E 2016 - 1490) counties. The first immatures were found on willows (Salix caroliniana Michx., Salicaceae) in Alachua Co. on 3. iii. 2017 (FSCA # E 2017 - 1199, 1552).

C23E8784FFE9FF9F5FA79C662F724D61.taxon	discussion	Comments. Salix is a predominantly Holarctic genus which was at least twice successfully colonized by psyllids, viz. by species of Cacopsylla and of Bactericera. In Salix and both psyllid genera the identification of species is difficult for the non-specialist as often interspecific differences are small and intraspecific variation is pronounced. The Nearctic Cacopsylla species associated with Salix spp. have been studied in detail (e. g. Jensen 1951; Hodkinson 1978) but not those of Bactericera. In the series of papers “ American Psyllidae ”, Crawford (1910 a, 1910 b, 1911 a, 1911 b) erected eleven new species and forms of Trioza associated with Salix. Most of his descriptions and illustrations are not diagnostic. In the monograph on the psyllids of the New World, Crawford (1914) synonymized several of his taxa recognizing five species of Salix inhabiting triozids: Ceropsylla californica (Crawford), Trioza arizonae Aulmann, T. maura Foerster (with five synonyms), T. salicis Mally (with five synonyms and three replacement names) and T. varians Crawford. Caldwell (1938 a) and Tuthill (1943) followed mostly Crawford (1914) but noted the name T. salicis Mally cannot be used for reasons of homonymy. Caldwell (1939) introduced the replacement name Phylloplecta multidubiata, an unnecessary action as there were available names for this taxon among the synonyms of T. salicis Mally. Tuthill (1943) chose the oldest synonym, T. minuta, as valid name and included T. arizonae as a variety of the former. He also moved T. californica from Ceropsylla back to Trioza. Tuthill’s (1943) species concepts were adopted in the catalogues of Hodkinson (1988) and Burckhardt and Lauterer (1997 b). The last two authors redefined Bactericera and included all previous Trioza species that developed on Salix. They pointed out that B. minuta of Crawford (1914), Caldwell (1938 a) and Tuthill (1943) was a species complex. The specimens from Florida fit the broad concept of Bactericera minuta by the North American authors. We have examined the relevant types (USNM) of the species currently listed as synonyms of B. minuta: i. e. Trioza assimilis Crawford, T. marginata Crawford, T. minima Crawford, T. minima similis Crawford, T. nigra Crawford and T. salicis Mally. We conclude that the types of the six nominal taxa represent three species but there are additional undescribed species in the USNM misidentified as Trioza minuta by J. S. Caldwell and L. D. Tuthill. Hence, all published records of Bactericera (or Trioza) minuta are doubtful. The three species we recognize here should be named Bactericera flori, B. minuta and B. nigrilla. The synonymies of the first two are detailed in Appendix 1. Here we discuss the ones of B. nigrilla. Trioza salicis Mally nec Linnaeus, Trioza nigra Crawford nec Kuwayama and Trioza minuta similis Crawford represent the same species, confirming, in part, Crawford’s (1914) synonymies. It differs from related species as indicated in the key in Appendix 1. It should be called Bactericera nigrilla Crawford for the following reasons. Trioza salicis Mally, 1894, constitutes a junior secondary homonym of Chermes salicis Linnaeus, 1761 (in Trioza). According to Löw (1882), Chermes salicis Linnaeus is congeneric with five European Trioza species developing on Salix (Trioza albiventris Foerster, 1848, T. curvatinervis Foerster, 1848, T. maura Foerster, 1848, T. salicivora Reuter, 1876, and T. striola Flor, 1861). All these species are now referable to Bactericera (Burckhardt and Lauterer 1997 b). As the description of Linnaeus (1761) is not diagnostic, Löw (1882) considered T. salicis Linnaeus a nomen dubium. Junior secondary homonyms are available as species names when the homonymy is removed by transfer to another genus. As Trioza salicis Mally and Chermes salicis Linnaeus are congeneric, independent if in Trioza or in Bactericera, and despite the fact that the latter is a nomen dubium, Trioza salicis Mally cannot be used as valid species name. The next oldest is Trioza nigra Crawford, 1910, a junior primary homonym of Trioza nigra Kuwayama, 1910, with the replacement names Trioza nigrilla Crawford, 1911, and Trioza louisianae Aulmann, 1912. The former is older and has priority and should, therefore, be used for the species under discussion as Bactericera nigrilla (Crawford, 1911), new combination and revived status. Another synonym, Trioza minuta similis Crawford, 1911, is deemed to be infra-subspecific and, therefore, invalid (ICZN 1999 / 2012: Article 45.6.4). Crawford (1911 a) used the name “ similis ” for three taxa: the species Trioza similis Crawford, 1910 (a junior subjective synonym of Trioza albifrons Crawford, 1910), and the two forms Trioza fulvida similis Crawford, 1911, and Trioza minuta similis Crawford, 1911. Later, Crawford (1914) referred to the last taxon as Trioza minuta var. similis, indicating that he considered these forms as varieties rather than subspecies. Caldwell (1939), finally, proposed the replacement name Phylloplecta multidubiata for Trioza salicis Mally nec Linnaeus, which we consider a junior objective synonym of Bactericera nigrilla. Bactericera nigrilla is characterized by the following combination of characters: long genal processes; black head; antennal color; lanceolate forewings bearing surface spinules; relatively short posterior lobes on the male proctiger; digitiform, apically pointed parameres; relatively short apical dilatation of the aedeagus with the moderately long sclerotized end tube of the ductus ejaculatorius; short female terminalia; apically truncate female proctiger and subgenital plate. There is some variation in the shape of the posterior lobes of the male proctiger (Fig. 162, 163) and the distal segment of the aedeagus (Fig. 166 – 169). These differences are mostly due to the state of preservation of the specimens, the types being older than a century, to a lesser degree also to individual variation. The genal processes of the types of Trioza minuta similis appear slightly shorter. The types appear to represent young specimens lacking the very dark color, which may also explain the shorter genal processes. More material, including long series from all over North America, will be necessary to test our conclusions.	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FFEEFFE15FA79DC329A24D9D.taxon	discussion	Comments. Virtually nothing is known about this psyllid. According to the description, it was found in Bonefish Key, which has been subsumed by Fat Deer Key (Monroe County). As far as we know, it has never been collected again. This species was described by Tuthill (1944 a) in Rhinopsylla Riley, 1885, probably because the head that is “ scarcely cleft anteriorly. ” When synonymizing Rhinopsylla with Bactericera Puton, 1876, Burckhardt and Lauterer (1997 b) transferred the species to the artificial genus Trioza Foerster, 1848, as it did not fit the generic definition of Bactericera. Tuthill (1944 a) mentioned in his description the broadly rounded genae, similar to Kuwayama Crawford, 1911, and the large clypeus. While Kuwayama in its present definition is highly artificial, it can be restricted to a group of triozids defined by the rounded genae, the adpressed, hemispherical eyes, the large bulbous clypeus and the long rostrum. The group is Neotropical in distribution and restricted to Compositae. As Trioza caldwelli fits this definition, we formally transfer it here as Kuwayama caldwelli (Tuthill, 1944), comb. nov. from Rhinopsylla.

C23E8784FF91FFE15FA79B242FFA48F8.taxon	discussion	Comments. Leuronota fagarae was recognized first in North America when a population was found by DPI inspectors Mark Runnals and Phillip Baioni on Zanthoxylum fagara at a nursery in Sarasota (Sarasota County, FSCA # s E 2001 - 2772, 2909, 3222). This psyllid was described from Paraguay, and, prior to its discovery in Florida, it was not known to occur outside of South America. The Sarasota infestation was traced to another nursery in Delray Beach (Palm Beach County) (FSCA # E 2001 - 3353). Other infestations were found in Palm Beach County at Atlantic Dunes Park (FSCA # s E 2001 - 3352, 3353), a private park in Miami (Miami-Dade County, E 2001 - 3552) and in a greenhouse in Gainesville (Alachua County, FSCA # E 2002 - 5273). The populations at the original Sarasota nursery and in the greenhouse were eradicated. Examination of old unknown psyllid collections in the FSCA revealed a collection by F. Smith on 19. vi. 1981 from Cape Canaveral (Brevard County) Florida, also collected from Z. fagara. This collection is our earliest record for this species. There are more recent collections from Lee (FSCA # 2009 - 1025), Hendry (FSCA # E 2009 - 5500), St. Lucie (FSCA # E 2009 - 8965), and Collier (FSCA # E 2012 - 2666) counties. Zanthoxylum spp. are considered medicinal plants in parts of South America, so we speculate that L. fagarae arrived on living Zanthoxylum plants or plant parts imported for personal use. Immatures roll the edges of the leaflets adjacent to the petiole. The psyllid did not appear to colonize or feed on citrus trees near heavily infested Zanthoxylum. The species is cultured easily on Z. fagara, and it did not colonize other Florida species of Zanthoxylum or Citrus in the laboratory (Russell et al. 2014). Transmission of Florida Candidatus Liberibacter asiaticus has not been demonstrated, and so far, the pathogen has not been found in Z. fagara.	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FF90FFE05FA79D262E554910.taxon	discussion	Comments. For a number of years, DPI inspectors have noticed a triozid on Avicennia. In 2003, it was identified as Leuronota maritima. The psyllid was described from Mexico and reported from Colombia (Rendón-Mera et al. 2017). Specimens at DPI go back to a large series from Manatee County collected on A. germinans on 15. vi. 1972 by Frank W. Mead. We also have specimens from Ft. Myers (Lee County) collected on A. germinans on 30. v. 1980 by K. Delate, from Hollywood (Broward County) collected on A. germinans on 20. i. 1993 by Karolynne Vanyo, from Green Key Park (Pasco County) collected on A. germinans on 25. v. 1989 by Cindy Kamelhair, from Miami-Dade County collected on A. germinans (FSCA # s E 2003 - 169, 441, 568, 2174), from North Palm Beach (Palm Beach County) collected on A. germinans (FSCA # E 2003 - 2147), and from Fleming Key (Monroe County) collected in traps in 1979 and 1980. Although we have specimens dating from nearly 50 years ago, this species has not been reported formally from Florida. We consider it adventive because of the rather sudden appearance of damaging populations on mangroves. The triozids roll the edges of new leaves (Fig. 183), severely damaging the new growth (Fig. 184). The damaged portion of the leaf eventually turns black and falls off. Immatures (Fig. 182) secrete copious sticky wax inside the rolled leaves. Tuthill (1944 b) described the species as Trioza; however, characters of the head, pronotum, metatibiae and male and female terminalia place this species in Leuronota, as defined by Burckhardt (1988) and Brown and Hodkinson (1988). The immatures (Fig. 182) have the thickened antennal segment 3 also characteristic for Leuronota. Here we formally transfer the species as Leuronota maritima (Tuthill, 1944), comb. nov. from Trioza.

C23E8784FF90FFE55FA799BF29BD490F.taxon	discussion	Comments. Nothotrioza Burckhardt is a small Neotropical genus with three described species from Brazil inducing globular leaf galls (Carneiro et al. 2013). Two species are associated with Psidium spp. (Myrtaceae) and one was reported from an unidentified species of Malpighiaceae which is, however, a misidentification of a Psidium species (R. G. S. Carneiro, pers. comm.). In recently collected material from Brazil, there are at least as many undescribed species inducing globular leaf galls on Psidium spp. Nothotrioza longipedis shares with the other Nothotriza species the lack of genal processes and the large number of metatibial spurs in the adults, the 3 - segmented antennae and the V-shaped outer circumanal ring in the immatures, as well as the association with Myrtaceae and the gall-inducing habit. It differs from the Brazilian species in the smaller body size, the less inclined head, the less hairy (shorter and sparser) vertex and thoracic dorsum, the dorsally less arched thorax, in details of the male and female terminalia, the very narrow, elongate last instar immature, with an apically rounded abdomen which is dorsally sclerotized and modified into an almost circular disc. It differs also in the pouch galls it induces on the host leaves, as opposed to the globular galls produced by Brazilian species.

C23E8784FF97FFE75FA79C0628BA4A71.taxon	discussion	Comments. Trioza adventicia Tuthill, 1952, described from New Zealand, is the correct name for Trioza eugeniae auct. nec Froggatt, 1901 (Taylor and Martoni 2020). This species does not occur in Florida, but it is intercepted in Florida on Syzygium paniculatum Gaertn. (especially on topiaries) (Mead 1994 b). Taylor and Martoni (2020) had specimens from California and Florida. They state clearly that the populations in Florida have been eradicated, and FSCA numbers given in the paper match those in our records of intercepted populations. We have 15 recorded interceptions of this species since 1985.	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FF97FFE75FA79A1F2E2249CF.taxon	discussion	Comments. This species, widely distributed in Florida, induces pouch galls on Persea borbonia and Persea palustris (Mead 1963). Although the insect was named after sweetbay, Magnolia virginiana L. (Magnoliaceae), this is an unlikely host. It is possible that Ashmead (1881) confused one of the Persea species with M. virginiana (Mead 1963). Significantly, T. magnoliae does not colonize Persea americana Mill.

C23E8784FF97FFEB5FA799F129EE48F8.taxon	discussion	Comments. Trioza myresae is a member of the Trioza russellae group defined by Brown and Hodkinson (1988) as follows: genal processes small, compound eyes large, metatibiae with 1 + 2 sclerotized apical spurs, forewing with short evenly curved vein Rs and small cell m 1. Four Neotropical species are included in the group: Trioza russellae Tuthill on Brosimum alicastrum (Moraceae), as well as T. arribensis Brown and Hodkinson, 1988, T. inequalis Brown and Hodkinson, 1988, and T. novalata Brown and Hodkinson, 1988, without host information. Trioza myresae differs from the last two species in the strict trifurcation of vein R + M + Cu of the forewing (rather than bifurcation into veins R + M and Cu), the slightly longer genal processes, the paramere which is distinctly shorter than the male proctiger (rather than longer) and the shorter female terminalia. From the first two species, T. myresae differs in the apically slender, forward pointing paramere and the slender, hook-shaped distal segment of the aedeagus. From T. russellae it differs in the host plant and general body shape of the immature, oval and flattened in T. myresae, and very narrow and elongate in T. russellae.	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FF86FFF65FA79FFE29EE4C09.taxon	discussion	Comments. Crawford (1914: 91) listed under Trioza salicis Mally the following synonyms: Trioza assimilis Crawford nec Flor and its replacement names Trioza flori Crawford and Trioza pomonae Aulmann, Trioza dubia Patch, Trioza nigra Crawford nec Kuwayama and its replacement names Trioza nigrilla Crawford and Trioza louisianae Aulmann, as well as Trioza minuta Crawford and Trioza minuta var. similis Crawford. Later Tuthill (1943: 555) questioned the synonymy of T. dubia and synonymized it instead with Trioza longicornis Crawford, an act which was followed by Hodkinson (1988). According to the original descriptions, the forewing of T. longicornis is broadly rounded but that of T. dubia subacute suggesting they are not conspecific. On the other hand, T. assimilis Crawford and T. dubia are congeneric and share the slender falcate paramere that is curved cephalad, the relatively long cuneate female terminalia with a pointed subgenital plate and their origin from California. We believe they are conspecific and synonymize them. As Trioza assimilis Crawford is a primary homonym of Trioza assimilis Flor, the name is not available and the oldest synonym, i. e. Trioza flori, has to be used which is transferred here to Bactericera as Bactericera flori (Crawford, 1911), comb. nov.	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.

C23E8784FF86FFF95FA79BAA28074D01.taxon	discussion	Comments. The examination of types of Trioza minuta and T. marginata Crawford (USNM) showed the two are conspecific. Specimens of the former are very teneral but bear indistinct brown areas along the hind margin of the forewing, a character not mentioned by Crawford (1911 a). The species is characterized by the narrow dark band along the hind margin of the forewing, often lighter and less expanded in males, the presence of surface spinules on the forewing membrane, the straight, relatively short posterior lobes on the male proctiger (Fig. 158), the lamellar paramere (Fig. 159), the long apical inflation (half as long as segment) of the distal segment of the aedeagus with very short sclerotized end tube of the ductus ejaculatorius (Fig. 160, 161) and the short, apically truncate female subgenital plate (see also key in Appendix 1). There is some variation in the antennal coloration and the extent of the dark wing pattern. In the types of T. minuta the antennal segments 3 – 8 are light and 9 – 10 dark brown, in the types of T. marginata Crawford segments 4 – 8 gradually darken towards the antennal apex; in specimens from Mexico (NHMB, USNM) only segment 3 is light and segments 4 – 10 are dark brown or black, strongly contrasting from segment 3.	en	Halbert, Susan E., Burckhardt, Daniel (2020): The psyllids (Hemiptera: Psylloidea) of Florida: newly established and rarely collected taxa and checklist.
