Urvaschia pterosticta : Hopp, 1987: 226: original description; Slater and O’Donnell 1995: 78: catalogue.

Type material examined.

Holotype (Fig. 1a, d ) • Nepal ♂; Bumra-Chhurchi [pr] / Logna 3350m [pr] / Pina 2370m // Nepal, 1977 / W. Wittmer [pr] 29. V. [hw] // Urvaschia [hw] / pterodiasticta [hw] / HOPP [hw] / det. Hopp. I. 1987 [hw] // Holo- [hw] / Typus [pr] [red label] (NHMB).

Redescription.

Colouration. Head black. Antennae blackish brown with segments II and III yellowish brown. Anterior lobe of pronotum black, with a yellow mid spot in the anterior margin; posterior lobe brown with darker punctures. Scutellum black. Corium pale yellowish brown, with sparse obscure pale brown spots including exocorium; veins thick and brown; apical angle of corium with single small blackish brown spot. Colour of membrane similar to corium, with dark brown spots on distal margin and between brown veins. Femora blackish brown; tibiae yellow with both ends brown; colour of tarsi similar to apices of tibiae.

Structure. Head slightly declined, both dorsally and ventrally with very dense, deep, large punctures. Dorsal surface flat. Eyes slightly protruding laterally. Distance between posterior margin of eyes and anterior margin of pronotum approximately one fourth of diameter of eyes. Antennae covered with short dense oblique setae; apical 1/2 of segment I surpassing clypeus.

Pronotum trapezoid, swollen, calli slightly emergent. Anterior and posterior margin straight; lateral margins slightly arched. Pronotum covered with large, dense punctures. Clavus with three distinct shallow rows of large punctures, with middle row incomplete. Corium with scattered punctures between vein Cu and clavus; apical margin strongly concave, costal margin convex; apical angle elongated and narrow; total length of corium ~ 2/3 of hemelytra. Membrane relatively long and broad (Fig. 1a ); membranal veins thick and obvious; apex of membrane surpassing abdomen. Fore femora slightly thickened, without any spines (Fig. 1a ). Abdominal connexivum not exposed.

Pygophore (based on Hopp 1987): posterior margin of pygophore and cup-like sclerite fused; distal margin of cup-like sclerite without a deep incision. Parameres: outer projection large and rounded; inner projection very small and pointed.

Distribution.

Nepal ( Hopp 1987) (Fig. 4 ).

Remarks.

The female paratype from Kashmir (Fig. 1b ) of U. pterosticta has a straight and unicolourous exocorium, and the anterior margin of its pronotum and the antenna are uniformly dark. Therefore, it is identical with U. obscuripennis and not the holotype of U. pterosticta (Fig. 1a ); hence, Kashmir should be deleted from locality records of U. pterosticta .

It needs to be clarified that the labels of the holotype and paratype (Fig. 1d, e ) showed " Urvaschia pterodiasticta Hopp" instead of " Urvaschia pterosticta " as used in the original description.
