03F00D28AB08FF8A8145FB64FB63FDE8.taxon	diagnosis	Diagnosis Both sexes of L. dispersum sp. nov. can be recognized by the combination of tegula oval without extended posterior angle, mesepisternum punctate and metasoma brown. The female has a distinct oblique propodeal carina, T 2 – T 3 basolaterally with appressed tomentum, and T 2 – T 3 apical impressed areas distinctly, but finely punctate. In size and sculpturing, L. dispersum sp. nov. is similar to members of the L. parvum species complex, but can be recognized by the unmodified tegula. Females of L. enatum sp. nov. have finer mesoscutal punctures and the T 2 – T 3 apical impressed areas impunctate. Lasioglossum genaroi sp. nov. is similar, but has rugose to reticulate-rugose mesepisternal sculpturing and typically a larger body size, which in females is significantly larger on average (t = 3.2, df = 17.6, p = 0.005), and it has a darker blue colour. Lasioglossum amona sp. nov. is most similar, differing only in the female having a paler green integument, a honey-coloured tegula, a smoother mesepisternum and a less distinct oblique propodeal carina.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB08FF8A8145FB64FB63FDE8.taxon	etymology	Etymology The specific epithet is taken from the Latin for “ scattered, dispersed ”, which is a reference to the ability of this species and its ancestors to colonize islands in the Caribbean. The Latin dispersum is a participle in the nominative neuter singular.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB08FF8A8145FB64FB63FDE8.taxon	biology_ecology	Biology Lasioglossum dispersum sp. nov. has been collected from flowers of Waltheria indica L. (Malvaceae). Individuals from Guana Island were collected from Antigonon leptopus Hook. & Arn. (Polygonaceae), Jacquemontia pentanthos (Jacq.) G. Don (Convolvulaceae) and Capparis cynophallophora L. (Capparaceae). Snelling (1993) also recorded this species from Schaefferia frutescens Jacq. as Lasioglossum sp. 2.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB01FF898170FD3BFAF2F981.taxon	diagnosis	Diagnosis Both sexes of L. amona sp. nov. can be recognized by the combination of tegula honey-coloured and oval without extended posterior angle, mesepisternum distinctly punctate, interspaces polished and metasoma brown. The female has a distinct oblique propodeal carina, T 2 – T 3 basolaterally with appressed tomentum and T 2 – T 3 apical impressed areas distinctly, but finely punctate. In size and sculpturing, L. amona sp. nov. is similar to members of the L. parvum species complex, but can be recognized by the unmodified tegula. It is closely allied to L. dispersum sp. nov., but differs in the female by the smoother mesepisternal sculpturing of interspaces, finer mesoscutal punctation, smoother dorsolateral slope and less distinct oblique carina. The male can only be distinguished from those of L. dispersum sp. nov. by the paler green colour and honey-coloured tegula. Lasioglossum genaroi sp. nov. is related, but has rugose to reticulate-rugose mesepisternal sculpturing and typically a larger body size, which in females is significantly larger on average, and a darker blue colour.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB01FF898170FD3BFAF2F981.taxon	discussion	Remarks Lasioglossum amona sp. nov. is very closely related to L. dispersum sp. nov. The differences in microsculpture and structure are suggestive of species-level differences, but it seems probable that these two species share a recent ancestor. Additional study is needed to determine whether the morphological and geographical basis for recognizing L. amona sp. nov. as distinct from L. dispersum sp. nov. is valid.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB1DFF908175FE99FB70FBE7.taxon	diagnosis	Diagnosis Both sexes of Lasioglossum enatum sp. nov. can be recognized by tegula punctate, extended posteriorly to form small angle, mesepisternum punctate and metasoma brown. The shape of the tegula distinguishes it from all other species of L. (Dialictus) from Puerto Rico, except L. monense sp. nov. on Mona Island. The female of L. monense sp. nov. has a pale metasoma and obscure punctation on the supraclypeal area. The male of L. enatum sp. nov. has the mesoscutum and mesepisternum more polished and shiny than in males of L. monense sp. nov. Other members of the L. parvum species complex, to which it belongs, share this character. In the female, the complete absence of punctures on the apical impressed margins distinguishes L. enatum sp. nov. from L. parvum and L. busckiellum, which both have minute setose punctures in this area. In the male, the appressed sternal setae and dark tarsi distinguish L. enatum sp. nov. from L. parvum, which has sternal setae erect and tarsi pale.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB1BFF9C814DFB32FB2AFD5B.taxon	diagnosis	Diagnosis Both sexes of L. monense sp. nov. can be recognized by the following: tegula punctate and extended posteriorly to form small angle, mesepisternum punctate and metasoma reddish brown to brown. The shape of the tegula distinguishes it from all other species of L. (Dialictus) from Puerto Rico, except L. enatum sp nov. Other members of the L. parvum species complex, to which it belongs, share this character. Females differ from L. enatum sp. nov. by the more obscure supraclypeal punctures, finer mesoscutal punctation with more densely tessellate interpsaces, smooth dorsolateral slopes, and brownish red metasomal terga. The male has the mesoscutum and mesepisternum duller than in L. enatum sp. nov. due to microsculpture. In the female, the complete absence of punctures on the apical impressed margins distinguishes L. monense sp. nov. from L. parvum and L. busckiellum, which both have minute setose punctures in this area. In the male, the appressed sternal setae and dark tarsi distinguish L. monense sp. nov. from L. parvum, which has sternal setae erect and tarsi pale.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB1BFF9C814DFB32FB2AFD5B.taxon	discussion	Remarks Lasioglossum monense sp. nov. could be considered a subspecies of L. enatum sp. nov., although use of this category can be controversial (Zink et al. 2016). The differences in microsculpture are similar to species-level differences, but it seems probable that these two species share a very recent ancestor.

03F00D28AB17FF9B82AAFC8FFE65FAF8.taxon	diagnosis	Diagnosis Both sexes of L. ferrerii are easily recognized by the combination of head relatively long (length / width ratio = 0.99 – 1.01), mesoscutal punctures dense, except medially, mesepisternum rugose, metapostnotum short, with complete carinulae, and metasoma metallic green-blue. The large size, head shape and metallic metasoma make L. ferrerii very distinctive. Lasioglossum mestrei is superficially similar, but has short carinulae on the metapostnotum and lacks the rugose sculpturing on the mesepisternum.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB17FF9B82AAFC8FFE65FAF8.taxon	distribution	Distribution Lasioglossum ferrerii is recorded here from Cuba, Jamaica, Hispaniola and Puerto Rico (Fig. 17). Eickwort (1988) records the “ ferreri [sic] sp. group ” as being present on the same four islands. Genaro (2007) and Genaro & Franz (2008) also list the species from these same four regions. Moure (2007) did not recognize the synonymy with Halictus proangularis and only lists the country of the type locality for each name in their distributions.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB17FF9B82AAFC8FFE65FAF8.taxon	biology_ecology	Biology Eickwort (1988) illustrated a nest of L. ferrerii from a “ grassy upper beach area of Luquillo Beach, Puerto Rico. ” The nest consisted of a simple vertical burrow dividing into three main branches and reaching a maximum depth of about 24 cm (based on the scale provided). Six cells were illustrated, each oriented horizontally and attached to the main burrow by a short lateral tunnel or with this lateroid filled in with soil. Three multi-female nests were excavated; all occupants were inseminated, reproductive females. The number of nest-mates was few in all cases (less than 5). Eickwort (1988) concluded on this basis that L. ferrerii forms communal nests. The ancestral behavioural state for L. (Dialictus) is believed to be eusocial nesting (Gibbs et al. 2012 b). DNA barcodes Three individuals were used for DNA barcoding. In each case, Wolbachia (Rickettsiales) was amplified instead of the bee. Smith et al. (2012) documented that standard barcode primers are not well suited for amplifying halictid bees.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB13FFA48175FE99FBE1FED0.taxon	diagnosis	Diagnosis Both sexes of L. genaroi sp. nov. can be recognized by the combination of head wide (length / width ratio = 0.89 – 0.94), mesoscutum with coarse, relatively sparse punctation (i = 1 – 3 pd), tegula ovoid, mesepisternum rugose to reticulate rugose and metasoma dark brown, nearly entirely lacking in appressed tomentum. Lasioglossum genaroi sp. nov. is a quite large L. (Dialictus), being similar in size to L. ferrerii. In direct comparison, size alone is often enough to distinguish L. genaroi sp. nov. at a glance from L. gundlachii, L. dispersum sp. nov. and L. enatum sp. nov.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB2FFFA182BCFE03FA9AFECC.taxon	diagnosis	Diagnosis Both sexes of L. gundlachii can be recognized by the metapostnotum with incomplete carinulae reaching from anterior margin to midlength, posterior half of surface smooth, mesopleuron relatively smooth, with distinct sparse punctures and mesoscutal punctures sparse between parapsidal lines. Female L. gundlachii have T 1 with acarinarial fan nearly absent, only visible as small lateral patches of subappressed setae. Male L. gundlachii can be recognized by long lateral setae on posterior metasomal sterna, which protrude in horn-like tufts, distinctly visible when examining the metasoma in dorsal view. Lasioglossum mestrei also has incomplete carinulae on the metapostnotum, but it has a much larger head, denser mesoscutal punctures and metallic reflections on the metasoma.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB2FFFA182BCFE03FA9AFECC.taxon	discussion	Taxonomic notes Two other species in the region belong to the gundlachii species group: L. liguanense (Sandhouse, 1924) from Jamaica and L. flaveriae (Mitchell, 1960) from southern Florida. The Puerto Rican material of L. gundlachii seems to have less dense punctation on the mesoscutum than do specimens examined from Cuba. It is possible that L. gundlachii is a senior synonym of L. flaveriae, a species known only from southern Florida and the Bahamas (Gibbs 2011). Gibbs (2011) noted differences in microsculpture between L. flaveriae and “ Jamaican specimens of L. gundlachii ”. It is evident from examination of additional West Indian material that the Jamaican specimens examined by Gibbs (2011) were in fact L. liguanense. There are also species present in Central America (e. g., Belize) and Mexico that have close affinities to the gundlachii group (J. Gibbs, unpublished data), suggesting that this species complex may have colonized the Caribbean from this region rather than from Florida. The description of the species L. albitarsatum (Ashmead, 1896), from Bahía Honda, Cuba, seems to match either L. gundlachii or L. mestrei. Lasioglossum albitarsatum has priority over both names. The type material of L. albitarsatum is evidently lost and the uncertainty in application makes it a nomen dubium.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB2FFFA182BCFE03FA9AFECC.taxon	biology_ecology	Biology Eickwort (1988) illustrated a nest of L. gundlachii from the same “ grassy upper beach area of Luquillo Beach, Puerto Rico ”, where nests of L. ferrerii were also found. The nest was less deep than that of L. ferrerii, reaching a maximum depth of approximately 11 cm. The nest was of similar construction, with eight cells attached to the primary burrows by short lateroids. Three multi-female nests were excavated. In two nests, there was a single reproductive female and a single worker. The third nest contained four inseminated females. Based on his observations, Eickwort (1988) concluded that L. gundlachii formed eusocial or semisocial nests, or occasionally communal ones. Lasioglossum gundlachii has been recorded visiting the following flowers: Barbieria pinnata (Pers.) Baill. (Fabaceae), Coriandrum sativum L. (Apiaceae) and Margarita sp. (Euphorbiaceae).	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB2FFFA182BCFE03FA9AFECC.taxon	description	DNA barcodes Two specimens were sent for sequencing, but efforts on only one of these were successful (BOLD Process ID: BOWGF 3194 - 14). The sequence is identical to a GenBank sequence (Accession: AF 103965) of L. gundlachii from Puerto Rico for the 417 bp in common (Danforth 1999). There is also a short fragment of CO 1 available from L. flaveriae in Florida (n = 1) with a maximum overlap of 531 bp between the Florida sequence and the Puerto Rican sequences (n = 2). These sequences show less than 0.8 % sequence divergence between the regions, which is within expected levels for a single species. Additional study of the gundlachii group through its range is warranted to better understand the taxonomy and historical biogeography of the group. Another species in this group, L. liguanense, is endemic to Jamaica.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB2AFFAC82E0FDB7FB37F9E6.taxon	diagnosis	Diagnosis The female of L. eickwortellum is easily recognized by the bright blue-green to purple head and mesosoma, long face (length / width ratio> 1.04) and metasoma with T 1 – T 2 orange-red, T 3 – T 6 brown with metallic reflections. The male of L. eickwortellum is similar to the female, but has more extensive testaceous colouration on the metasoma, as well as yellow / testaceous colour on the clypeal distal margin; mandible and all legs are entirely yellow. Both sexes have three submarginal cells and mesoscutum with distinctive dense punctures that are closely packed over the entire surface. It is easily distinguished from L. (Habralictellus) rufopanticis, which has a wide face, sparse mesoscutal punctures, typically two submarginal cells and different patterns of metasomal colour (usually all orange-red or all brown).	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB2AFFAC82E0FDB7FB37F9E6.taxon	discussion	Remarks This species was described based on a single female specimen. Three additional females and two males have been examined. The male is described above for the first time. An unusual feature of the male is the pectinate inner metatibial spur, which appears similar to that of the female. This is unusual for males of Lasioglossum, although it is present in species formerly classified as the subgenus Sudila Cameron, 1898 (Sakagami et al. 1996) (now included in Hemihalictus s. lat. (Gibbs et al. 2013 )). Males of L. (Habralictellus) eleutherense (Engel, 2001) from Half Moon Cay, Bahamas (FSCA) and L. (H.) rufopanticis (Engel, 2001) from Mona Island also have pectinate inner metatibial spurs (contra Engel 2001 b). This character supports uniting these species groups within L. (Habralictellus) — as does the unusual male genital capsule, which has unusually broad gonostyli and lacks a retrorse lobe (Engel 2001 b: figs 1 – 2). Males of L. sierramaestrense (Genaro, 2001) have finely dentate inner metatibial spurs with shorter and more numerous teeth than the female spur. The holotype and paratype male of L. obamai Genaro, 2016 do not have toothed inner metatibial spurs and the genitalia look quite different from those of L. eickwortellum and L. rufopanticis, having slender elongate gonostyli and distinct retrose lobes (Genaro 2016: fig. 16). The females of all known species of L. (Habralictellus) lack the T 1 appressed fan, which is present in most North American members of L. (Dialictus), but not all species (Gibbs 2009 b, 2010 b, 2011). The large size, bright metallic reflections, and absence of an appressed T 1 fan of the adriani group species of L. (Habralictellus) is similar to the situation in some Neotropical species of Lasioglossum (J. Gibbs, unpublished data). Two members of L. (Habralictellus) occurring in the Lesser Antilles, Lasioglossum auratum (Ashmead, 1900) and L. punctifrons (Crawford, 1914), show close affinity to L. eickwortellum, particularly in the shape of the head and the presence of three submarginal cells (Gibbs 2016). Both of these species lack the dense and distinct mesoscutal punctures and seem to have entirely dark metasoma.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB27FFAB8294F90DFEF7FC14.taxon	diagnosis	Diagnosis Both sexes of L. rufopanticis have the head and mesosoma iridescent green, head round, mesoscutum shiny and sparsely punctate, and submarginal cells two. They are easily distinguished from L. eickwortellum by the shape of the head (see above). They are similar to L. eleutherense, but that species has the mesosoma very dull due to distinct microsculpture and the female has distinct integumental banding on the metasoma.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB20FFA8829FFB18FEEAF816.taxon	discussion	Remarks Lasioglossum busckiellum was described from the Island of St. Domingo, now Hispaniola, probably from the Dominican Republic. This species belongs to the Lasioglossum parvum species group, which includes bees also referred to as the L. tegulare species group (Ellis 1914 a; Gibbs 2009 a). Wolcott (1948) recorded L. busckiellum from Puerto Rico based on specimens identified by Krombein and Sandhouse. Both L. busckiellum and L. parvum have distinctive punctation in the apical impressed areas of the metasomal T 2 – T 3, which are absent in all L. parvum group specimens examined from Puerto Rico, including one identified as L. busckiellum by Krombein. Lasioglossum busckiellum has darker tegula than does L. parvum. Some specimens of L. enatum sp. nov. seem to have dark tegula suggestive of L. busckiellum.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB22FFB682ABFE99FB66FC52.taxon	discussion	Remarks There has been some recent and past confusion regarding this species, such that some individuals recently reported to be L. mestrei are misidentified specimens of L. gundlachii. Historical records may be due to confusion over the secondary homonymy of the two Cresson (1865) names Augochlora parva and Panurgus parvus. It was first recorded from Puerto Rico as Augochlora parva by Dewitz (1881). Baker (1906) treated A. parva and P. parvus as if they belonged to the same species, which was accepted by later authors (Cockerell 1910; Alayo 1973, 1976). The lectotype designations for these two names by Cresson (1916) invalidates this interpretation. Some records of L. mestrei from Puerto Rico may be derived from specimens of L. enatum sp. nov. due to the earlier use of the Cresson names.	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.

03F00D28AB3DFFB782BAFB81FAF7FA75.taxon	discussion	Remarks The Lasioglossum parvum species group is widespread in the New World, and includes members of the L. tegulare species group (Danforth 1999; Danforth et al. 2003; Gibbs 2009 a; Gibbs et al. 2012 b). The parvum group is common in the Greater Antilles. Lasioglossum busckiellum from Hispaniola (see above) and L. gemmatum (Smith, 1853) from Jamaica (= L. bruesi (Cockerell, 1912) syn. nov., = L. jamaicae (Ellis, 1914) syn. nov.), L. monense sp. nov. and L. enatum sp. nov. all belong to this group. The name L. parvum has undoubtedly been applied too broadly in the past to include multiple species, probably including most of the above, as well as possibly undescribed species in this complex from Cuba, Jamaica and the Bahamas (Gibbs, unpublished data). Dewitz (1881) and Gundlach (1887) recorded it from Puerto Rico as Panurgus parvus, but the bee diversity of the region was not well known at that time. All specimens belonging to the parvum group examined from Puerto Rico were L. enatum sp. nov. or L. monense sp. nov. from Mona Island. Several specimens of the parvum group with two submarginal cells in at least one wing were examined from the Bahamas and Cayman Islands. Record details for these specimens are as follows:	en	Gibbs, Jason (2018): Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies.
