Redescription.

Colouration. Head black. Antennae blackish brown, sometimes with segments II and III yellowish brown. Bucculae and labium blackish brown, concolourous with clypeus. Anterior lobe of pronotum black, sometimes with anterior margin yellow; posterior lobe dark blackish brown, with a short yellow midline mark near posterior margin. Scutellum black. Corium pale yellowish brown, with sparse, obscure, pale brown spots except exocorium; veins thick and brown; apical angle of corium with single blackish brown spot. Colour of membrane similar to corium, with dark brown spots between brown veins. Thoracal sterna black. Supracoxal lobe of prosternum blackish brown. Ostiolar peritreme of metathoracic scent gland blackish brown. Posterior 1/2 of mesopleuron and metapleuron broadly yellowish white. Femora blackish brown; tibiae yellow with both ends yellowish brown to blackish brown; colour of tarsi similar to apexes of tibiae. Abdominal sterna dark reddish brown.

Structure. Head slightly declined, both dorsally and ventrally, with very dense, deep, large punctures and erect white setae (ventrally decumbent). Dorsal surface flat. Eyes slightly protruding laterally. Distance between posterior margin of eyes and anterior margin of pronotum ~ 1/2 diameter of eyes. Bucculae high, covering labium, with sparse punctures. Antennae covered with short dense oblique setae; apical one quarter of segment I surpassing clypeus. Labium reaching base of mesocoxae, first segment of labium almost reaching posterior margin of bucculae.

Pronotum trapezoid, flat, calli slightly emergent. Anterior and posterior margin straight; lateral margins of pronotum slightly sinuate; both anterolateral and posterolateral pronotal angles round. Pronotum covered with large, dense punctures (smaller on calli) and long, white, erect setae, slightly leaning posteriad. Base of scutellum sunken, basal 1/2 covered with small punctures and with similar setae as pronotum; apical 1/2 of scutellum without middle ridge, only lateral margins with small punctures. Hemelytra flat, sparsely covered with short white setae; clavus with three clear rows of large shallow punctures, with middle row incomplete. Corium with scattered punctures between vein Cu and clavus, and a row of dense punctures along inner margin of exocorium, apically being superficial, sometimes absent there; apical margin strongly concave, costal margin almost straight; corium evenly broadening posteriad, body broadest near apex of corium; apical angle elongated and narrow; total length of corium ~ 2/3 of hemelytra. Membrane comparatively long, broad, inner ca 1/3 overlapping each other (Figs 1c View Figure 1 , 2a View Figure 2 ); membranal veins thick and obvious; apex of membrane surpassing abdomen. Prosternum, propleura, and lateral part of mesopleura punctate, similarly to pronotum, meso- and metasternum with metapleura impunctate. Ostiolar peritreme of metathoracic scent gland strongly protruding, apically rounded, evaporatorium rounded, reaching> 3/4 over metapleura laterad. Fore femora slightly thickened, sometimes with a tiny spine (Fig. 2d View Figure 2 ). Abdominal connexivum not exposed. Abdomen impunctate, abdominal sternum covered with sparse setae.

Pygophore: posterior margin of pygophore and cup-like sclerite fused; distal margin of cup-like sclerite with a deep incision (Fig. 3a View Figure 3 ). Parameres (Fig. 3b, c View Figure 3 ): outer projection small and rounded; inner projection very small and pointed; blade approximately bent rectangularly to shank of paramere in lateral view.

Measurements (mm, N = 8). Body length 2.68-3.50. Head length 0.34-0.47, width across eyes 0.60-0.72; antennal segments I-IV length: 0.17-0.26: 0.37-0.56: 0.27-0.32: 0.40-0.45; labium length 0.96, first segment length 0.23. Pronotum length 0.55-0.68, width of anterior margin 0.48-0.54, width of posterior margin 0.68-0.88; scutellum length 0.31-0.39, width 0.33-0.50. Distance apex clavus-corium apex 0.74-0.97; distance apex corium - apex membrane 0.70-0.88.

Distribution.

China (Sichuan, Yunnan); India (Kashmir, Uttarakhand) ( Hopp 1987); Iran (Alborz, Sistan and Baluchestan); Afghanistan (Badakshan); Tadzhikistan (Fig. 4 View Figure 4 ).

Remarks.

As mentioned above, the female paratype of U. pterosticta from Kashmir (Fig. 1b View Figure 1 ) was transferred to this species. Meanwhile, the original distribution information from China of this species should be considered a misidentification; see the detailed comments of Urvaschia convexa sp. nov.

Differential diagnosis.

Urvaschia obscuripennis is similar to U. pterosticta in having similar brown spots on the hemelytra and apex of the corium conspicuously concave, but the lateral margin of the corium is almost straight and the exocorium spotless, the lateral margins of pronotum are slightly sinuate (vs. lateral margin of the corium more arched and exocorium with brown spots; the lateral margins of the pronotum more arched in U. pterosticta ), and the distal margin of the cup-like sclerite with a deep incision (vs. distal margin of cup-like sclerite without any incision but with a median keel in U. pterosticta ).
