4A3FBB30C6668F63C640DB7E4E3FFDCE.taxon	diagnosis	DIAGNOSIS: Recognized by weakly flattend, lanceolate, silvery or white setae generally distributed on dorsum and thoracic pleuron, intermixed with pale or dark, reclining, simple setae (figs. 1 C, 17 D), elongate nearly parallel­sided body form in males contrasted with ovate body form of females (figs. 7 – 12), broad, usually short head in males (figs. 7 – 12), and small, relatively simple vesica of male genitalia (figs. 13 – 16) with apex blunt or as a single or bifid, short apical projection, and gonopore sclerite (when present) lacking barbs. Coloration often largely red or green, a few species castaneous, but then appendages often partly to entirely red. Known species feeding on halophytes, primarily members of Ephedraceae, Chenopodiaceae, and Solanaceae. Megalopsallus was confounded by Knight (1968) with Europiella Reuter, but is easily distinguished by the more flattened body form in most species, the simpler, more delicate structure and much smaller size of the male genitalia, and the preference for halophytic hosts rather than members of the Asteraceae. Some dark­colored species, such as knowltoni and nigrofemoratus are similar in appearance to some Plagiognathus species, but are always separable by the form of the male genitalia; furthermore, most Plagiognathus spp. have only simple setae on the dorsum and elsewhere on the body. The pulvilli are sometimes large and cover most of the ventral claw surface in Megalopsallus (figs. 18 C, 20 D, but see fig. 17 E), whereas in Plagiognathus the pulvilli are always small and cover only a small area near the base of the claw. As noted above, Knight’s (1927) characterization of pulvillar structure in Megalopsallus was in error.	en	SCHUH, RANDALL T.

4A3FBB30C6668F63C640DB7E4E3FFDCE.taxon	description	REDESCRIPTION: Male: Small to moderately large species, total length 2.31 – 5.20, length apex clypeus – cuneal fracture 1.73 – 3.31, width across pronotum 0.83 – 1.32; usually elongate and more or less parallel sided (figs. 7 – 12). COLORATION AND VESTITURE: Coloration, including all appendages, ranging from totally pale, white, to almost totally black, often greenish or reddish. Vestiture of dorsum comprising reclining or recumbent, pale to dark, simple setae intermixed with white, silvery, or rarely somewhat golden, weakly to moderately flattened, usually lanceolate, sometimes woolly, setae (figs. 7 – 12), latter type also occurring on thoracic pleuron and abdominal venter. Tibial spines pale or dark, with or without dark spots at bases. STRUCTURE: Body form generally somewhat flattened; head broad, short longitudinally and clypeus not visible from above. Eyes sometimes bulging and removed from pronotal margin, more commonly conforming to curvature of frons and to anterior pronotal margin. Antennal segment 2 cylindrical (figs. 5, 6) or more rarely spindleshaped, especially in females (fig. 23). Hemelytra often elongate to strongly elongate and nearly parallel­sided, abdomen often reaching only to cuneal fracture, less frequently hemelytra not so elongate and body form elongate ovoid. Metathoracic scent­gland evaporatory area as in figs. 1 B, 3 B, etc.; mesothoracic spiracle with an elongate, conspicuous area of ‘‘ mushroom bodies’ ’ dorsad of spiracle (figs. 3 B, 4 B). Claws ranging from relatively short and curving only near apex (fig. 1 D) to relatively long and slender, smoothly curving over entire length (fig. 17 E); pulvilli ranging from minute (fig. 17 E) to large and covering nearly entire ventral claw surface (fig. 18 C). Abdomen in males flattened dorsoventrally, broad basally and broadly curving and narrowing toward relatively small genital capsule (fig. 17 B). MALE GENITALIA: Genital capsule and genitalia small relative to size of animal (fig. 17 B); vesica formed of a single strap usually twisted to form an S shape (figs. 13, atriplicis), more rarely forming a weak coil (fig. 13, brendae) or not twisted and in the shape of a J (figs. 16, punctatus); apex of vesica often sclerotized and attenuated, as either a single spine or bifid, sometimes membranous; (secondary) gonopore either apical or subapical, occasionally only weakly sclerotized; gonopore sclerite subtending gonopore often present and well sclerotized (figs. 13 – 16, gs), never with barbs as in many Atractotomus species; paramere and phallotheca typical of Phylini, without distinctive characteristics (figs. 14 – 16). Female: Total length 2.28 – 3.98, length apex clypeus – cuneal fracture 1.74 – 2.96, width across pronotum 0.96 – 1.42; often broadly oval to elongate ovoid and of more robust body form than males (figs. 7 – 12); antennal segment 2 of slightly smaller diameter than in males, sometimes spindle­shaped (fig. 23).	en	SCHUH, RANDALL T.

4A3FBB30C6668F63C640DB7E4E3FFDCE.taxon	discussion	DISCUSSION: Comparison of the 29 species here recognized within Megalopsallus indicates that the continued treatment of Merinocapsus as a separate group almost certainly renders the former group paraphyletic. Therefore, Merinocapsus is treated as a junior synonym of Megalopsallus. The affinities of Megalopsallus appear to be with Atractotomus Fieber, Knightomiroides Stonedahl and Schwartz, Phoenicocoris Reuter, Pinomiris Stonedahl and Schwartz, and possibly Chlamydatus Curtis, based particularly on the male genitalic structure, the genitalia being relatively small, the vesica being formed of a single strap, and the subapical secondary gonopore frequently being subtended by a gonopore sclerite (Kelton, 1965; Stonedahl, 1990; Stonedahl and Schwartz, 1996). Although several Megalopsallus species have the gonopore sclerite (figs. 13 – 16, gs) described by Stonedahl (1990), none have barbs on the sclerite. The apex of the vesica in Megalopsallus is usually attenuated, in the form of a single, short, simple spine, or is bifid. Atractotomus, Chlamydatus, and Phoenicocoris are Holarctic in distribution, whereas the other genera are restricted to the Nearctic. In addition to the above described morphological differences, the host associations in Megalopsallus are distinctive within this related group of genera. Megalopsallus spp. are restricted to halophytes in the genus Ephedra of the primitive seed­plant group Ephedrales and among the angiosperms pri­ marily to several genera in the Chenopodiaceae and to the solanaceous genus Lycium. Knightomiroides, Phoenicocoris, Pinomiris, and some Atractotomus spp. feed on the Coniferales with the remaining Atractotomus spp. breeding on a variety of angiosperms; none are known to feed on the Chenopodiaceae, Solanaceae, or Ephedraceae (Stonedahl, 1990; Stonedahl and Schwartz, 1996). A very few other Nearctic Phylini feed on halophytes. Among those that do is Tannerocoris sarcobati Knight, 1970, which is found only on Sarcobatus, but which shows no obvious relationship with Megalopsallus on the basis of habitus or male genitalic morphology. The Holarctic species Atomoscelis onustus (Fieber), 1861, belonging to an otherwise Palearctic group, apparently feeds exclusively on ruderal chenopods; most Nearctic records of this species are as Atomoscelis modestus (Van Duzee), 1914 [see Kerzhner and Schuh, 1998, for synonymy with Atomoscelis onustus (Fieber)]. The vesica of Atomoscelis appears always to be formed of a single strap basally, but is divided in two at the base of the secondary gonopore, a condition never seen in the species here assigned to Megalopsallus. Furthermore, Atomoscelis spp. are usually ovate and much less strongly sexually dimorphic than Megalopsallus spp. A few other Palearctic Phylini merit examination as possible Megalopsallus relatives on the basis of morphology and / or host preferences. They are discussed here with the objective of determining whether Megalopsallus as a monophyletic group extends beyond the Nearctic. Camptotylidea Wagner comprises 28 species (Konstantinov, 1999) occurring primarily in desert areas; many of them feed on chenopods. The vestiture of Camptotylidea is composed of only simple setae and the vesica is always extended apically well beyond the secondary gonopore, unlike the conditions found in all species here assigned to Megalopsallus.	en	SCHUH, RANDALL T. (2000): Revision of the North American Plant Bug Genus Megalopsallus Knight, with the Description of Eight New Species from the West (Heteroptera: Miridae: Phylinae).

4A3FBB30C6668F63C640DB7E4E3FFDCE.taxon	description	Nasocoris Reuter from the Mediterranean and adjacent areas appears to feed exclusively on Ephedra (Schuh, 1995), which might suggest a relationship with Megalopsallus. However, the clypeus is distinctively flattened and extended and antennal segment 1 is moderately to greatly elongate and clothed with long to very long more­or­less erect setae. The vesica appears to be formed of a single strap, as in Megalopsallus, and the genital capsule is relatively small. The general appearance and coloration of Nasocoris tesquorum Kerzhner are similar to those of Megalopsallus pallidus and the dorsal vestiture is also similar to that of Megalopsallus spp. (Wagner, 1973). Psallomimus Wagner, with one species in Egypt and the rest of its species further south in Africa (Schuh, 1995), has relatively small genitalia and the vesica is formed of a single strap as in Megalopsallus. However, the vestiture is always of simple setae, and the bugs are otherwise Plagiognathus ­ like in appearance. The only known host record is from Solanum sp. (Linnavuori, 1993). Psallopsis Reuter has 15 described species from the Mediterranean, Middle East, and Central Asia; all breed on members of the Chenopodiaceae (Schuh, 1995). Although host preferences in Psallopsis might suggest a relationship with Megalopsallus, the male genitalia indicate otherwise, the vesica being formed of two chitinous straps, rather than one as is the case in Megalopsallus (Wagner, 1975). In conclusion, it appears that Megalopsallus as here diagnosed is restricted to the Nearctic, and within that region to halophytic plant groups. My conception of Megalopsallus is relatively broad, because when treated otherwise the result would be several more difficult to diagnose genera. Although Megalopsallus shows its greatest species diversity in saline environments in interior western North America, it also occurs in the eastern United States — primarily along the coastline — from Texas to Connecticut, and most recently has been recorded from coastal halophytes in the Dominican Republic. Unfortunately, eastern North American is relatively poorly collected and few host records are available, in stark contrast to the West where nearly all species have well­documented hosts. The following key to species is designed for use with male specimens. For most species the description of coloration will also pertain to females, although table 1 will have to be consulted for measurements. For a few species it will be necessary to dissect the male genitalia to be confident of the identification. Sometimes host information will allow accurate identification of species such as humeralis and nigrofemoratus, which on the basis of external morphology and coloration may be virtually indistinguishable.

4A3FBB30C6638F6DC7C0DAC74DB0F9E9.taxon	discussion	DISCUSSION: In the present paper atriplicis is conceived as widespread and not strongly host specific. This approach might be revised under more critical analysis. My treatment is influenced by the fact that genitalia cannot be used to readily recognize this species, or to distinguish it from nuperus and rubropictipes, in particular. Also, nearly all material from the eastern part of the range, including the type locality, was from older collections, which made comparisons of coloration difficult. Finally, a vast section of the western plains and Rocky Mountains was virtually unrepresented in the available sample of material.

4A3FBB30C66D8F73C500DC534DA2FB74.taxon	discussion	DISCUSSION: Knight (1927) described brittoni and adustus on the same page, separating them primarily on the length of the second antennal segment. Although this measurement was frequently used by Knight to discriminate species, I have found it to be less reliable than was believed by Knight, owing to variability within species. I have seen only two specimens of brittoni, and have compared them with large numbers of specimens from Texas, including the holotype of adustus from Anahuac, that agree closely with Knight’s concept of adustus. I am treating adustus as a junior synonym of brittoni because both nominal taxa have brown spots at the bases of many of the setae on the dorsum, an attribute found elsewhere in Megalopsallus only in punctatus, the last species otherwise showing little similarity to brittoni.

4A3FBB30C66D8F73C500DC534DA2FB74.taxon	discussion	DISCUSSION: This species is similar to brittoni, especially in coloration and the weak sexual dimorphism. However, available specimens of femoralis are all smaller than those of brittoni, with no size overlap between the two taxa. The male genitalia, although similar, appear to show consistent differences. Also, as here construed, the distributions of the two taxa are nonoverlapping.

4A3FBB30C66D8F73C500DC534DA2FB74.taxon	discussion	DISCUSSION: I have collected large numbers of specimens of this species on hosts identified as Sarcobatus vermiculatus var. baileyi. Although specimens collected by O’Brien are labeled as occurring on S. vermiculatus, I have never encountered specimens on ‘‘ true’ ’ vermiculatus, and conversely, most records of vermiculatus ­ feeding species are not known from var. baileyi. Therefore, host data for the bugs suggest that baileyi represents a distinct plant species. This species was collected at more than one locality on specimens of Sarcobatus baileyi also inhabited by a mite belonging to the genus Balaustium (Erythraeidae), which was very similar in appearance and coloration to the females of flammeus. Adults of Balaustium spp. are free­living predators of small arthropods, whereas the larvae are ectoparasites of the same. The relationship, if any, of the mites and the bugs in this particular cases is not known. On the occasion of first collecting this brightly colored bug species my field companions and I dubbed it ‘‘ the mite mimic’ ’ in recognition of the rather strong similarity of appearance of the two taxa.

Most easily confused with nigrofemoratus on basis of size, coloration, and type of sexual dimorphism; separated most easily by differences in structure of male genitalia, vesica being more elongate and slender in nigrofemoratus than in humeralis, and fact that nigrofemoratus feeds on Atriplex and Grayia (Chenopodiaceae) rather than Lycium (Sola­ naceae), the latter appearing as exclusive host of humeralis. Pale specimens separated from Lycium ­ feeding nicholi by cuneus being unicolorous with corium, rather than of at least moderately contrasting coloration as in nicholi.	en	SCHUH, RANDALL T.

4A3FBB30C66D8F73C500DC534DA2FB74.taxon	discussion	DISCUSSION: Knight (1968) described the new species arizonae, balli, brevicornis, lycii, rufiventris, and viridiventris from the southwestern United States. Comparison of the types and other specimens examined by Knight with holotype of Megalopsallus humeralis (Van Duzee) [‘‘ Loreto, Baja California, May 20, 1921, EP Van Duzee Collec­ tor, ’’ male (CAS)], including dissections of the male genitalia of most of these nominal species, indicates that even though there is substantial variation in color and size, the male genitalia are very similar for all of them and distinct from all other species of Megalopsallus. I am therefore treating all of these nominal taxa as synonymous, humeralis having priority. The holotype and paratypes of humeralis are faded, like many other Van Duzee specimens, appearing somewhat lighter in color than would be expected of fresh material. Megalopsallus humeralis shows substantial size variation. The structure of the male genitalia is relatively constant across the range of other forms of variation. Table 1 presents the measurements for this species in two nonoverlapping groupings of ‘‘ small’ ’ and ‘‘ large’ ’ specimens, reflecting the fact that in most populations the specimens are either relatively large or relatively small. A massive amount of material with carefully documented hosts indicates that humeralis invariably feeds on Lycium spp. The records of specimens from other plant groups offer little evidence for them as alternative hosts. I have collected extensively on all of the plant taxa listed above under ‘‘ hosts, ’’ and never recorded Megalopsallus breeding on any other than Lycium.

Most easily confused with pale specimens of humeralis (fig. 9), the latter also breeding on Lycium spp.; distinguished from humeralis by darkened cuneus contrasting with remain­ der of hemelytra. Genitalia also absolutely distinctive from those of humeralis. Also similar in general appearance to Sarcoba­ tus ­ feeding rubricornis (fig. 11), but that species always with cuneus unicolorous with remainder of pale hemelytra and head, with pronotum and scutellum often more strongly reddish.	en	SCHUH, RANDALL T.

4A3FBB30C64F8F4CC500D8C24EF3F919.taxon	discussion	DISCUSSION: Knight (1968) placed pallidus in Nevadocoris on the basis of pulvillar structure, coloration, and antennal structure. Examination of the male genitalia indicates that pallidus is a Megalopsallus species, a placement corroborated by its known occurrence only on species of Atriplex and Grayia (Chenopodiaceae). Nevadocoris becki, the type of the genus in which pallidus was originally placed, has male genitalia dissimilar in structure to those of species here placed in Megalopsallus and breeds on members of the Asteraceae, including Tetradymia and Chrysothamnus.

4A3FBB30C64F8F4CC500D8C24EF3F919.taxon	diagnosis	DIAGNOSIS: Recognized, in common with punctipes and sarcobati, by generally pale green coloration, including appendages, white eyes, and pale brown spots on femora (fig. 10). Distinguished from them by infuscate thoracic sternum and form of male genitalia (compare figs. 15 and 16), and also from Sarcobatus ­ feeding sarcobati by that species’ larger size and broader head. Similar in size and general appearance to sparsus, but eyes almost always black in sparsus; also sparsus usually with some dark areas on head, pronotum, and femora. Distinguished from generally pale schwartzi by red eyes of that species and its lack of spots on femora.	en	SCHUH, RANDALL T.

4A3FBB30C64A8F57C594DE954869FF22.taxon	discussion	DISCUSSION: Knight (1968) described Psallus atriplicis as occurring on Atriplex at the Nevada Test Site. Examination of the male genitalia indicates clearly that this is not a Psallus species but rather belongs to Megalopsallus, even though it is somewhat unusual because of the spotting on the dorsum. The name atriplicis Knight becomes a junior secondary homonym upon transfer of this species to Megalopsallus, and I therefore propose the new name punctatus.

Distinguished most easily from parapunctipes by lack of infuscation on thoracic sternum and form of male genitalia (fig. 16), and from sarcobati by larger size and broad­ er head of that species as well as form of male genitalia. Similar in size and general appearance to sparsus, but eyes almost always black in sparsus; also sparsus usually with some dark areas on head, pronotum, and femora. Distinguished from schwartzi by that species having red eyes and lacking spots on femora.	en	SCHUH, RANDALL T.

4A3FBB30C6578F52C7C0DB0848BCFF0F.taxon	discussion	DISCUSSION: Examination of the material upon which Knight (1970) based his original description of multipunctipes indicates that this nominal taxon is the same as sarcobati, and I am therefore treating it as a junior synonym. Knight noted that his specimens of multipunctipes ‘‘ were from a shrub I thought must be an Atriplex. ’’ All verified host records for this species are from Sarcobatus, Knight’s observation apparently being in error.

4A3FBB30C6578F52C7C0DB0848BCFF0F.taxon	diagnosis	DIAGNOSIS: Recognized by elongate slender body form in male, entirely pale greenish white coloration, red eyes (fig. 12), and lack of brown spots on femora and tibiae. Commonly collected with atriplicis and sarcobati, but distinguished from former by that species having red spots on head and pronotum and from latter by that species having pale eyes, brown spots on femora, and more robust body form.	en	SCHUH, RANDALL T.
