Bisulcopsallus , new genus

Type species: Phymatopsallus huachucae Knight.

DIAGNOSIS: Recognized by the novel development of the anterior process of the left paramere with a bifid (cloven) apex (figs. 7–12), in combination with the pale coloration, spotted dorsum in most specimens of most species (fig. 1), and the presence of an elongate, sometimes flattened, spine arising from the ventral surface of the phallotheca (figs. 7–12); pygophore in male always very large with a tubercle on the left side (fig. 6E, F). Medium-sized to moderately large within the Phymatopsallus group, total length 2.44–3.50. Most similar to Ceratopsallus in structure of the male genitalia, especially the spine on the ventral surface of the phallotheca, the strongly elongated right paramere, and the distinct separation of the posterior process of the left paramere from the paramere body. Readily distinguished from Ceratopsallus by the cow horn-shaped anterior process of the left paramere and the usually shorter ‘‘non-filamentous’’ vesica in species of that group (figs. 14–23). Bisulcopsallus , as well as Angelopsallus and most Ceratopsallus spp. , separated from most other members of the Phymatopsallus complex by the weak sexual dimorphism in the antennae and the eyes.

DESCRIPTION: Male: Moderately small to moderately large among Phymatopsallus - group taxa, elongate ovoid to nearly parallelsided, total length 2.44–3.50, length apex clypeus–cuneal fracture 1.59–2.30, width pronotum 0.82–1.10. COLORATION (fig. 1): Body and forewings pale or faded green, sometimes weakly orange; corium, clavus, cuneus, and sometimes head, pronotum, and scutellum with heavy spotting of green, orange, or brown; eyes ranging from silvery or pale to nearly black; coloration of appendages pale, greenish, or weakly orange, femora with scattered, weak, brown spots; tibial spines dark with dark bases; membrane marmorate, usually with some conspicuous large dark areas, especially posterior to the cuneus; veins of membrane pale. SURFACE AND VESTI- TURE (figs. 1, 6C): Dorsal body surface smooth, impunctate, weakly shining. Dorsal vestiture with recumbent, silvery setae. STRUCTURE: Head: Weakly transverse, posterior margin of eyes contiguous with anterior margin of pronotum, frons weakly protruding beyond anterior margin of eyes; posterior margin of vertex lacking distinct margin; eyes not enlarged relative to those in female (fig. 1); antennae inserted above ventral margin of eye by roughly diameter of segment 1, insertion contiguous with eye (fig. 6A), segment 2 weakly tapered and similar to female; labium reaching from posterior margin of middle trochanters to well past posterior margin of hind trochanters. Thorax: Mesothoracic spiracle and metathoracic scent-efferent system as in figure 6B. Legs: Claws strongly bent preapically, pulvilli flaplike, parempodia setiform (fig. 6D). Abdomen: Broad. GENI- TALIA (figs. 6E, F, 7–12): Pygophore: Very large, almost quadrangular, occupying at least half the length of abdomen, on left side with a distinct tubercle beset with numerous setae (fig. 6E, F). Vesica: Formed of a single, slender, filamentous strap, varying from long to very long, much of vesica occupying pregenital abdomen in repose (fig. 6F); attenuated apically and extending beyond secondary gonopore by about 2 times length of gonopore; secondary gonopore relatively small, well sclerotized, ovoid, without gono- pore sclerite. Phallotheca: Apical portion elongate, relatively slender, tapered, dorsal margin near apex sometimes with a triangular fold, ventral margin always with an elongate, usually slender (sometimes flattened) spinelike process. Parameres: Left paramere with anterior process uniquely with a bifid (cloven) apex, posterior process relatively short, flattened, and straight, always with knoblike ornamentation apically; right paramere relatively large, elongate, nearly parallel-sided, curving to the right as viewed from above, apex with a distinct, short, equally developed process on either side.

Female: Elongate ovoid; total length 2.28– 3.41, length apex clypeus–cuneal fracture 1.66–2.41, width pronotum 0.86–1.16. COL- ORATION (fig. 1): As in male. SURFACE AND VESTITURE: As in male. STRUC- TURE: Hemelytra extending just beyond apex of abdomen; eyes similar in size to those of male (fig. 1); antennal segment 2 tapered toward base. GENITALIA (figs. 8, 11): Sclerotized rings vaguely triangular; vestibulum tubular, greatly elongated, entrance and exit closely apposed at base of ovipositor valves, turning point of vestibulum forming a ‘‘chamber’’ at which point the channel of vestibulum doubles back on itself; posterior wall either simple or with a transverse sclerotized area in the shape of a yolk near its posterior margin (figs. 8, 11).

ETYMOLOGY: From the Latin bisulcus, cloven or forked, and Psallus , in reference to the forked nature of the anterior process of the left paramere, in combination with the generic name Psallus . Gender masculine.

HOSTS: Recorded from a variety of hosts, with the largest numbers of records being from Quercus spp. (Fagaceae) , a lesser number from Fraxinus spp. (Oleaceae) , and all other records represented only by a single host collection event.

DISCUSSION: Although generic placement of Bisulcopsallus spp. is unproblematic, especially upon examination of the male genitalia with the filamentous vesica and cloven anterior process of the left paramere, distinguishing the species is not always straightforward. Although the male genitalia provide some useful distinguishing features, even there the species appear to show some variability, which at times confounds making positive identifications.

? Bisulcopsallus croceguttatus (Knight) , tentative new combination figure 1

Phymatopsallus croceguttatus Knight, 1964: 137 (n.sp).

DISCUSSION: Knight (1964) described this taxon from a single female specimen (USNM) from Texas Pass [Summit], in southeastern Arizona, at an elevation of approximately 5000 feet. At that same locality he also collected a long series of Phymatopsallus rinconae Knight (identified by him as Phymatopsallus strombocarpae Knight ) on Strombocarpa (5 Prosopis ) pubescens . I am only tentatively assigning the name croceguttatus to Bisulcopsallus , because positive identifications to genus in the Phymatopsallus group are most easily made through the examination of male specimens; ascertaining species identities without recourse to male genitalia could be made through dissection of the female, but only the female holotype is available. Owing to our less than comprehensive survey of the females, I have chosen not to dissect the holotype as a way of further testing the validity of the generic placement of this nominal taxon, because such action would add no new distributional information at the generic level and would not confirm or reject the specific identity of B. croceguttatus in the context of our current knowledge of female genitalic structure in the Phymatopsallus group. The specimen is large, total length 3.24, length apex clypeus–cuneal fracture, 2.29, width pronotum 1.03; the dorsum is irregularly and rather sparsely covered with relatively large orange spots. It does not fit easily in any of the other described species of Bisulcopsallus on the basis of size and coloration, nor does it fit well with known Ceratopsallus spp. on the basis of distribution, although the size and type of spotting are reminiscent of Ceratopsallus croceus (Van Duzee) .

Bisulcopsallus fulvipunctatus (Knight) , new combination figures 1, 7; map 2

Phymatopsallus fulvipunctatus Knight, 1964: 137 (n. sp).

DIAGNOSIS: Recognized by the relatively small size among Bisulcopsallus spp. , average length approximately 2.7, the pale back-

50% scale of other structures; right paramere only: AMNH_PBI 00055983).

ground coloration with dull orange spots primarily on the coriaceous parts of the hemelytra (fig. 1), the relatively short vesica among Bisulcopsallus spp. , the slender phallothecal spine, the anterior process of the left paramere with relatively heavy spines, the posterior process of the left paramere more or less blunt apically, and the right paramere relatively broad at apex (fig. 7). Most similar in size and coloration to B. huachucae (Knight) (fig. 9); separated by its spotting and overall coloration of the body usually being less intensely orange, but with greatest certainty by the structure of the male genitalia, the phallotheca spine in B. fulvipunctatus being slender, that in B. huachucae being conspicuously flattened over its entire length, the apicoventral portion of the phallotheca being more strongly flared in B. huachucae , the posterior process of the left paramere being distinctly separated from the paramere body and the apex being more or less blunt, whereas in B. huachucae the posterior process not distinctly separated from paramere body and the apex in the form of a slender projection. Also similar to B. texanus (figs. 1, 12) in size, but that species usually more distinctly greenish or nearly devoid of spots and the posterior process of the left paramere not showing a distinct separation from the body of the paramere.

REDESCRIPTION: Male: Moderately small among Bisulcopsallus spp. , elongate ovoid, total length 2.55–2.79, length apex clypeus– cuneal fracture 1.83–1.85, width pronotum 0.91–0.93. COLORATION (fig. 1): Pale, faded orange, with dense covering of orange-brown spots on dorsum; membrane marmorate, without large dark areas, veins pale. SURFACE AND VESTITURE (fig. 1): As in generic description. STRUCTURE: Head: Labium reaching from posterior trochanters onto abdomen. GENITALIA (fig. 7): Vesica: Long, filamentous. Phallotheca: Phallothecal spine slender and weakly curving, reaching to near apex of phallotheca. Parameres: Left paramere with spines on anterior process heavy, closely set,

posterior process distinctly separated from paramere body; right paramere only very weakly narrowed apically.

Female: Elongate ovoid; total length 2.52– 2.93, length apex clypeus–cuneal fracture 1.59–1.96, width pronotum 0.88–0.95. COL- ORATION (fig. 1): As in male. SURFACE AND VESTITURE: As in male. STRUC- TURE: Similar to male. GENITALIA: Not examined.

HOST: None recorded.

DISTRIBUTION (map 2): Known from Santa Cruz County , southern Arizona, and Culberson and Travis Counties in western Texas.

DISCUSSION: The identity of this taxon has been fixed based on dissection of a male paratype from Patagonia, Arizona, and comparison with the undissected holotype male (USNM) with the same label data. Further comparisons were made with additional dissected male specimens from Texas. One topotypic paratype male, also dissected, belongs to B. huachucae .

Bisulcopsallus fuscipunctatus (Knight) , new combination figures 1, 8; map 2

Phymatopsallus fuscipunctatus Knight, 1964: 135 (n.sp).

DIAGNOSIS: Recognized by the relatively large size among Bisulcopsallus spp. , average total length approximately 3.2, the weakly greenish background coloration (often yellowish in preserved specimens) with mediumbrown spots on the coriaceous portions of the hemelytra, the very long vesica (more than 70 cm in 10X drawing), the slender phallothecal spine, the posterior process of left paramere without a conspicuous break separating it from the paramere body, the elongate body of the left paramere, the apex of the posterior process of the left paramere in the form of a slender protrusion, and the right paramere narrow rather than being conspicuously broad at apex. Most similar is size and coloration to B. polhemorum , new species (fig. 1); separated from it most readily by the form of the male genitalia, the vesica in B. fuscipunctatus (Knight) being very long (fig. 8), that in B. polhemorum much shorter, and the posterior process of the left paramere in B. fuscipunctatus not distinctly separated from the paramere body, the apex in the form of a narrow projection (fig. 8), whereas in B. polhemorum the posterior process distinctly separated from the paramere body and the apex of the process more or less blunt (fig. 11).

REDESCRIPTION: Male: Moderately large among Bisulcopsallus spp. , elongate ovoid, total length 2.91–3.40, length apex clypeus–cuneal fracture 1.91–2.32, width pronotum 0.94–1.06. COLORATION (fig. 1): Pale, faded greenish, with moderately dense covering of brown spots on clavus, corium, and cuneus; membrane marmorate (sometimes vaguely) with additional large dark areas posterior to cuneus and on posterior margin of cells, veins pale to infuscate. SURFACE AND VESTITURE (figs. 1, 6D): As in generic description. STRUC- TURE: Head: Labium reaching to posterior trochanters or slightly beyond. GENITA- LIA (fig. 8): Vesica: Very long, filamentous. Phallotheca: Phallothecal spine slender, reaching about two-thirds of distance toward apex of phallotheca, apex of phallotheca with a subapical triangular projection on dorsal margin. Parameres: Left paramere with spines on anterior process heavy, noticeably divergent, posterior process not distinctly separated from paramere body; right paramere moderately narrowed apically.

Female: Elongate ovoid; total length 2.83– 3.22, length apex clypeus–cuneal fracture 1.95–2.22, width pronotum 0.87–1.05. COL- ORATION (fig. 1): As in male. SURFACE AND VESTITURE: As in male. STRUC-

TURE: Similar to male. GENITALIA (fig. 8): See generic description.

HOST: Recorded from Shepherdia rotundifolia Parry (Eleagnaceae) , Quercus gambellii Nutt. and Quercus undulata Torr. (Faga- ceae), and Clematis ligustifolia Nutt. ex T. & G. ( Ranunculaceae ). A single specimen recorded from Artemisia tridentata Nutt. , but this certainly represents a sitting record.

DISTRIBUTION (map 2): Widely distributed from southern Idaho, across Utah, and into western Colorado and eastern Arizona.

DISCUSSION: The identity of this species is based on the dissection of specimens that are within the distributional range of the type locality (Y Mountain, near Provo, Utah) and are also similar in color and morphology to the holotype. This is the only species known from the most northerly parts of the combined range of Bisulcopsallus spp. , and along with B. polhemorum is restricted to higher elevations, with the two species showing overlap in eastern Arizona.

Phymatopsallus longirostris Knight, 1964: 136 (n.sp.). NEW SYNONYMY.

DIAGNOSIS: Recognized by the relatively small size among Bisulcopsallus spp. , average length approximately 2.7, the usually pinkish or yellowish background coloration with reddish orange spots on the entire dorsum, the very long vesica (more than 70 cm in 10X drawing), the flattened and moderately broad phallothecal spine, the phallotheca with a strong apicoventral flare, the anterior process of the left paramere with relatively weak spines, the posterior process of left paramere not conspicuously separated from the paramere body, the posterior process of the left paramere terminating in a more or less slender projection, and the right paramere relatively narrow along body and at apex. Most similar in size and coloration to B. fulvipunctatus (Knight) (fig. 1); separated by the spotting and overall coloration of the body usually being more intensely orange in B. huachucae than in other Bisulcopsallus spp. (fig. 1), but with greatest certainty by the structure of the male genitalia, the phallothecal spine in B. huachucae being conspicuously flattened over its entire length, the apex of the phallotheca flared ventrally, and the posterior process of the left paramere not conspicuously separated from the paramere body (fig. 9); in B. fulvipunctatus the phallotheca spine more nearly cylindrical, the apex of the phallotheca not flared ventrally, and the posterior process of the left paramere distinctly separated from the paramere body (fig. 7). Also similar to B. texanus in size, but that species usually more distinctly greenish or nearly devoid of spots (fig. 1) and the apicoventral portion of the phallotheca not so strongly flared as in B. huachucae (compare figs. 9 and 12).

REDESCRIPTION: Male: Moderately small among Bisulcopsallus spp. , elongate ovoid, total length 2.44–2.83, length apex clypeus– cuneal fracture 1.67–1.97, width pronotum 0.82–0.96. COLORATION (fig. 1): Usually with distinctly orange cast, with moderately dense covering of orange-brown spots on dorsum; membrane marmorate with additional dark area posterior to cuneus, veins pale. SURFACE AND VESTITURE (figs. 1, 6D): As in generic description. STRUCTURE: Head: Labium reaching to posterior trochanters or slightly beyond. GENITALIA (fig. 9): Vesica: Very long, filamentous. Phallotheca: Phallothecal spine flattened, reaching to near apex of phallotheca. Parameres: Left paramere with spines on anterior process of unequal length, weakly divergent, posterior process not distinctly separated from paramere body; right paramere moderately narrowed apically.

Female: Elongate ovoid; total length 2.28– 2.61, length apex clypeus–cuneal fracture 1.66–1.81, width pronotum 0.86–0.90. COL- ORATION (fig. 1): As in male. SURFACE AND VESTITURE: As in male. STRUC- TURE: Similar to male. GENITALIA (examined; not illustrated): See generic description.

HOST: Recorded from Quercus emoryi Torr. , Q. oblongifolia Torr. , and Q. turbinella Greene , Quercus sp. (Fagaceae) with a single specimen from Fraxinus velutina Torr. (Oleaceae) .

DISTRIBUTION (map 2): Ranging from southern Nevada and Utah through much of Arizona.

DISCUSSION: Although most specimens of this species are distinctly orange and relatively small among Bisulcopsallus spp. , some are more greenish and larger, based on comparisons of the male genitalia.

The identity of B. huachucae is fixed through dissection of the male genitalia of a topotypic paratype male, and comparison of this specimen with the holotype. Numerous additional specimens from across the range of the species were also dissected.

Knight’s (1964) description of Phymatopsallus rubropunctatus was based on one male (holotype) and one male and one female specimen from Payson, Arizona, collected by E.D. Ball on August 3, 1929. The relatively small size and reddish coloration suggest that B. rubropunctatus represents the same taxon as B. huachucae , and the former is here treated as a junior synonym of the latter on the basis of page priority. Knight (1964) compared this nominal taxon only with B. texanus (Knight) , saying: ‘‘Allied to texanus in structure of male claspers…, but distinguished by the long rostrum and in having conspicuous reddish dots on the dorsal surface.’’ The parameres in B. rubropunctatus are clearly of the type found in any of the six species here placed in Bisulcopsallus . The size and coloration of B. rubropunctatus are very similar to those of many specimens I have assigned to B. huachucae .

Bisulcopsallus longirostris (Knight) was described from 2 male and 2 female specimens from the Chiricahua Mountains of southeastern Arizona. Knight (1964) compared B. longirostris to B. huachucae , noting that the rostrum in B. longirostris was longer, reaching to the middle of the posterior trochanters. The specimen that Knight designated as the holotype is teneral, with the

rostrum being somewhat compressed under the head, indicating that it would actually reach well onto the abdomen, a condition seen in many of the specimens I have assigned to B. huachucae . The specimen is pale with weakly marked spots. Bisulcopsallus longirostris also fits well within the size range of larger specimens of B. huachucae . For these reasons, I am treating B. longirostris as a junior synonym of B. huachucae , on the basis of page priority.

Bisulcopsallus pallidus , new species figures 1, 10; map 2

DIAGNOSIS: Recognized by the relatively large size among Bisulcopsallus spp. , total length averaging 3.3, the entirely pale coloration, and the structure of the male genitalia, the left paramere with dorsal spine of the anterior process erect and conspicuously removed from the ventral spine, the posterior process lacking a distinct separation from the body of the paramere, and the phallotheca with a broad flare on the apicoventral surface (fig. 10) (the extent of this development approached only in B. huachucae ). Most similar in its pale coloration and broadened phallothecal process to some specimens of B. texanus (fig. 1), but distinguished from that species (and all other Bisulcopsallus spp. ) by the distinctive structure of the spines on the anterior process of the left paramere and the much broader apicoventral flare on the phallotheca (fig. 10).

DESCRIPTION: Male: Moderately large among Bisulcopsallus spp. , elongate ovoid, total length 3.19–3.50, length apex clypeus– cuneal fracture 2.10–2.38, relatively broad bodied, width pronotum 1.07–1.10. COLOR- ATION (fig. 1): Pale; membrane at most weakly marmorate, with limited dark area posterior to cuneus, veins pale. SURFACE AND VESTITURE (figs. 1, 6D): As in generic description.

Bisulcopsallus polhemorum , new species figures 1, 11; map 2

DIAGNOSIS: Recognized by the relatively large size among Bisulcopsallus spp. , average length approximately 3.0, the weakly greenish background coloration (often yellowish in preserved specimens) with medium-brown spots on the coriaceous portions of the hemelytra, the relatively short vesica, the relatively slender phallothecal spine, the posterior process of the left paramere distinctly separated from the paramere body, the relatively short body of the left paramere, the apex of the posterior process of the left paramere more or less blunt, and the right paramere narrowed and not conspicuously broad at apex (fig. 11). Most similar is size and coloration to B. fuscipunctatus (Knight) ; separated from it most readily by the form of the male genitalia, the vesica in B. polhemorum being relatively short, that in B. fuscipunctatus being much shorter (fig. 8), and the posterior process of the left paramere in B. polhemorum distinctly separated from the paramere body, the apex more or less blunt, whereas in B. fuscipunctatus the posterior process not distinctly separated from the paramere body and the apex of the process in the form of a slender projection (fig. 8).

DESCRIPTION: Male: Size moderate among Bisulcopsallus spp. , elongate ovoid, total length 2.70–3.21, length apex clypeus– cuneal fracture 1.91–2.14, width pronotum 0.91–1.04. COLORATION (fig. 1): Pale to weakly greenish, with moderately dense covering of greenish-brown spots on clavus, corium, and cuneus; membrane marmorate with additional dark area posterior to cuneus, veins pale. SURFACE AND VESTI- TURE (figs. 1, 6D): As in generic description. STRUCTURE: Head: Labium reaching to posterior trochanters. GENITALIA (fig. 11): Vesica: Very long, filamentous.

Bisulcopsallus texanus (Knight) , new combination figures 1, 12; map 2

Phymatopsallus texanus Knight, 1964: 134 (n.sp.).

DIAGNOSIS: Recognized by the relatively small size among Bisulcopsallus spp. , average length approximately 2.6, the pale background coloration with dull weakly brown spots on the coriaceous parts of the hemelytra and in some specimens restricted almost entirely to the cuneus (fig. 1), the relatively long vesica, the flattened, lanceolate phallothecal spine, the posterior process of the left paramere not conspicuously separated from the paramere body, the posterior process with a knoblike projection, and the right paramere relatively narrow at the apex (fig. 12). Most similar in size and coloration to B. fulvipunctatus and B. huachucae ; separated by the spotting and overall coloration of the body being greenish or pale rather than pink or orange as in those species (fig. 1), but with greatest certainty by the structure of the male genitalia, the phallothecal spine in B. texanus being flattened over its entire length and pointed apically (fig. 12), unlike B. fulvipunctatus , in which the apicoventral portion of the phallotheca much less strongly flared, and the posterior process of the left paramere not distinctly separated from the paramere body (fig. 7) as in B. huachucae .

REDESCRIPTION: Male: Size moderate among Bisulcopsallus spp. , elongate ovoid, total length 2.62–2.78, length apex clypeus– cuneal fracture 1.74–1.98, relatively broad bodied, width pronotum 0.87–1.00. COLOR- ATION (fig. 1): Pale background coloration, coriaceous portion of hemelytra either without spots or partially to completely covered with orange to brown spots; membrane marmorate, with limited dark area posterior to cuneus, veins pale. SURFACE AND VESTITURE (figs. 1, 6D): As in generic description. STRUCTURE: Head: Labium reaching to posterior margin of middle trochanters. GENITALIA (figs. 12): Vesica: Long, filamentous. Phallotheca: Phallothecal spine flattened, reaching to near apex of phallotheca, with serrate apicoventral margin. Parameres: Left paramere with spines on anterior process divergent, posterior process not distinctly separated from paramere body; right paramere narrowed apically.

Female: Elongate ovoid; total length 2.45– 2.81, length apex clypeus–cuneal fracture 1.75–1.87, width pronotum 0.90–0.94. COL- ORATION (fig. 1): As in male. SURFACE

AND VESTITURE: As in male. STRUC- TURE: Similar to male. GENITALIA: Not examined.

HOST: Known from Fraxinus cuspidata Torr. and Fraxinus sp. (Oleaceae) .

DISTRIBUTION (map 2): Ranging from Bexar County in west-central Texas to Cochise, Pima, and Santa Cruz Counties in southern Arizona.

DISCUSSION: The Arizona material was collected on Fraxinus spp. (Oleaceae) ; the host of the Texas specimens is unknown. The Texas specimens, from the ‘‘hill country’’ near San Antonio, show distinct and uniform spotting on the hemelytra, whereas those from Arizona have distinct spots only on the cuneus, with the corial spots indistinct in most specimens. The genitalia of a paratype male from the type locality and specimens from Arizona appear to be virtually identical, however, and I am therefore treating all of this material as a single species.
