Halys shaista Ghauri, 1988: 78, 88–92.
Colouration. Dorsum ochraceous with spots or streaks formed by clusters of dark brown or black punctures; antennae nearly concolourous with dorsum, apical three segments darker, apex of segment II and III and base of segment IV and V, ochraceous; scutellum with 1+1 spots at basal angles, black; connexivum concolourous with dorsum except for light to dark brown anterior and posterior fourths of connexival segments; hemelytral membrane light brown with black veins; ventral surface including labium and legs nearly concolourous or paler than dorsum except for black apical segment of labium, apices of tarsal segments and claws and anterior and posterior angles of ventrites and spiracular outline.
Integument and vestiture. Dorsum including head covered with dense, irregular dark brown to black punctures, sometimes forming irregular patches or spots. Ventral surface including legs with dark brown to black, coarse, dense punctures. Body glabrous.
Structure. Labium elongate reaching anterior margin of abdominal segment VII. Anterior and posterior margins of pronotum nearly straight. Humeri angulate, not elevated, disc of pronotum and scutellum more or less flat. Other characters as in generic description.
External male genitalia (Figs 61–76). Genital capsule. Quadrangular. Dorsal rim outlined with mat of minute, fine hairs, widely and shallowly excavated concave, with median short region, black and glabrous (Fig. 61); slightly notched adjacent to caudal lobes; infoldings with sublateral region sclerotized black with tooth reduced to mere sclerotized, minute serrations towards end of sclerotized region on either side of median black region (Fig. 94); ventral rim together with infoldings broadly and widely excavated concave, lack the median, inverted U-shaped process unlike in other species and with a median tumescence, notched medially (Fig. 62); 1+1 sclerotized, obliquely straight narrow ridge on sides of median tumescence on inner side; ridges reaching caudolateral margin of infoldings; infoldings well developed, elevated, laterally joined to caudal lobes by a minute V-notch. Paramere. Roughly C-shaped (Figs 64–66), with apically angulate and expanded crown, short stem and expanded plate-like apodeme. Crown with short, blunt, black tooth medially on dorsolateral margin. Phallus. Articulatory apparatus with basal plates and support bridge complex, dorsal connectives widened into 1+1 oval capitate processes (Figs 67, 98). Phallosoma sclerotized, constricted towards both ends, broadest medially and concave dorsally; two pairs of membranous conjunctival processes, dorsal pair elongate with bifid apex (Figs 69, 70), ventral pair shorter than dorsal pair (Figs 71, 72). Processes of aedeagus hard, sclerotized, fused along midline at proximal half encompassing short, sclerotized aedeagus and separated at distal half; distal half expanded into a subrectangular plate with rounded apical margin (Fig. 72); aedeagus obliquely bent upwards and shorter than processes of aedeagus.
External female genitalia (Figs 73–76). Terminalia. Valvifers VIII roughly triangular, with mesal margin straight, inner posterior angles rounded; posterior margin nearly straight or slightly convex. Valvulae VIII with apical (= caudal) margin not uniformly rounded, but distinctly indented medially (roughly broad W-shaped) forming two lobes (Fig. 76). Valvifers IX single, transverse, narrow, inverted trapezoidal sclerite. Laterotergite IX obliquely placed, not reaching apex of abdomen. Laterotergite VIII broad, elongate, triangular with nearly smooth caudal margin. Spermatheca (Fig. 73) apical receptacle orbicular with two finger-like processes, directed towards flanges.
Differential diagnosis. This species can be differentiated from other species of Halys by the peculiar shape of paramere and absence of inverted U-shaped process on ventral rim of genital capsule but with a median tumescence. The parameral crown is apically angulate, possessing a single tooth around the middle of its dorsolateral magin, triangular valvifers VIII with posterior margin nearly straight or slightly convex (Figs 74, 75) and valvulae VIII distinctly indented medially (roughly broad W-shaped) (Table 1).
