Stictopsallus View in CoL , new genus

Type species: Psallus aspersus Van Duzee.

DIAGNOSIS: Recognized among Phymatopsallus -group taxa by the relatively small size, pale greenish background coloration of the body, a uniform covering of small green or brown spots on the clavus, corium, and cuneus, and strong sexual dimorphism in the eyes and antennae (fig. 3), the absence of a tubercle and associated setae on the left side of the pygophore (fig. 38F, G), uniquely by the phallotheca with two hornlike processes projecting from the dorsal surface, and by the anterior process of the left paramere in the form of a finch beak (figs. 38G, H, 39). Vesica more or less J-shaped, gonopore distinctly sclerotized, subapical, with a short spine on the dorsal edge of the vesica at the midpoint of the gonopore (fig. 39), the last feature shared in a substantially similar form with Salicopsallus spp. Distinguished from Bisulcopsallus and Ceratopsallus by the smaller pygophore and the absence of a tubercle on the left side of the pygophore. Distinguished from Cercocarpopsallus and Salicopsallus by the presence of a group of short spinelike setae on the left side of the pygophore in the former and a tubercle with associated setae in the latter.

DESCRIPTION: Male: Moderately small among Phymatopsallus -group taxa, weakly to moderately elongate, nearly parallel-sided, total length 2.28–2.84, length apex clypeus– cuneal fracture 1.65–1.96, width pronotum 0.57–0.97. COLORATION (fig. 3): Body and forewings pale greenish, often yellowish in preserved specimens, with a uniform covering of small green or brown spots on the clavus, corium, and cuneus (fig. 3); eyes silvery or pale to dark; appendages pale, weakly yellowish to greenish; femora with scattered weak brown spots; tibial spines pale, with small weakly brown spots at bases; membrane weakly marmorate, veins pale. SURFACE AND VESTITURE (figs. 3, 38C, D): Dorsal body surface smooth, impunctate, weakly shining. Dorsal vestiture of reclining, pale, simple setae intermixed with recumbent, silvery, sericeous setae. STRUCTURE: Head: short, transverse, closely conforming to anterior margin of pronotum (fig. 3); frons at most barely protruding beyond anterior margin of eyes (fig. 38A); posterior margin of vertex round- ed; eyes large in dorsal and lateral views (figs. 3, 38A); antennae inserted above ventral margin of eyes by distance somewhat greater than diameter of antennal segment 1, antennal insertion contiguous with eye (fig. 38A); antennal segment 2 cylindrical, not tapered, about the same diameter as antennal segment 1 (fig. 3); labium reaching to about posterior margin of middle trochanters. Thorax: Mesothoracic spiracle and metathoracic scent-efferent system as in figure 38B. Legs: Claws moderately elongate, rather strongly curving, pulvilli flaplike, parempodia setiform (fig. 38E). Abdomen: Broad. GENITALIA (figs. 38F–H, 39): Pygophore: Moderately large, conical (fig. 38F, G). Vesica: Formed of a single relatively slender strap, roughly J-shaped, with onehalf twist proximal to secondary gonopore, apically, extending beyond secondary gonopore by distance equal to about length of gonopore; secondary gonopore small, well sclerotized, ovoid, without distinct gonopore sclerite, but with a small sclerotized appendage located on dorsal surface of vesica at about midpoint of gonopore. Phallotheca: Apical portion rather short, truncate, dorsal margin bearing two large curving hornlike spines. Parameres: Left paramere with anterior process flattened, sclerotized, and in the form of a finch beak, posterior process of form typical of Phylinae ; right paramere elongate, crudely parallel-sided, apex with pair of terminal processes weakly developed.

Female: Elongate ovoid; total length 2.43– 2.86, length apex clypeus–cuneal fracture 1.61–1.97, width pronotum 0.83–1.02. COL- ORATION (fig. 3): As in male. SURFACE AND VESTITURE: As in male. STRUC- TURE: Hemelytra just covering abdomen; eyes smaller than those of male, frons more prominently bulging anterior to eyes, head projecting below eyes by distance equal to somewhat less than diameter of antennal segment 1; antennal segment 2 more slender than in male, tapered toward base. GENI- TALIA (fig. 39): Sclerotized rings ovoid, weakly folded; vestibulum with small sclerites and no obvious elongate tubular development as so conspicuously seen in Angelopsallus , Bisulcopsallus , and Ceratopsallus ; posterior wall simple, posterior fourth laterally with small spicules and a sclerotized, transverse, median lobe.

ETYMOLOGY: Named for the spotted dorsum, from the Greek, stictos, spotted, in combination with the generic name Psallus . Gender masculine.

HOSTS: All available records indicate that the genus Stictopsallus is restricted to members of the Fabaceae .

DISCUSSION: Stictopsallus aspersus (Van Duzee) was not included by Knight (1964) in his treatment of Phymatopsallus , presumably because it does not have a tubercle on the left side of the pygophore. Nonetheless, the general appearance of S. aspersus is remarkably similar to many of the spotted species that Knight did include in his revision, and the structure of the right paramere and the marmorate membrane clearly argue for placement in the Phymatopsallus group.

Psallus aspersus Van Duzee, 1923: 159 (n.sp.).

DIAGNOSIS: Recognized by the characters given in the generic diagnosis.

REDESCRIPTION: See generic description.

HOST: Van Duzee (1923) recorded this taxon from a variety of localities in Baja California and also Santa Catalina Island, California, indicating that in all cases the specimens were taken on ‘‘palo tinto’’; this is almost certainly ‘‘palo de tinto’’, Haematoxylum brasiletto (Karst.) (Fabaceae) , which is known from mainland Mexico and Baja California. All more recently collected material examined for the present study was collected on Psorothamnus (5 Dalea ) spinosus (Gray) Barneby and Olneya tesota A. Gray (Fabaceae) .

DISTRIBUTION (map 8): Know from the southernmost counties in Arizona and California, south into northwestern Mexico and much of Baja California.

DISCUSSION: The identity of this species is based on the dissection of a male paratype (CAS) from Ceralbo Island, Baja California, Mexico, the type locality, and comparison with the holotype male.
