Figs 34A–L , 61R , 69A–D .

Idioscopus thapai Viraktaamth & Hongsaprug 1990: 1–2 , 4, fis 1–15.

Diagnosis. Yellowish white to ochraceous. Crown fore margin with one round spot on either side of median line, face ventrad of ocelli, dark brown to black except for a spot adjacent to antennal base and one on lorum. Pronotum with large dark brown to black patch on disc anteriorly varying in length. Exposed mesonotum with basal triangles and one median stripe becoming paired on scutellum, dark brown to bblack. Forewing with a basal and apical part of outer claval vein especially in male ivory. Forewing with 3 subapical cells. Male pygofer dark pigmented with median transverse unpigmented stripe, without ventral process. Style with group of thin long setae near apex on dorsal surface. Aedeagus with large dorsal apoeme which is laterally expanded subapically in posterior view, shaft distally narrowed, almost straight for most of the length and slightly curved anteriorly near apex.

Description. Female. Sternite VII about 1.8× as wide at base as long medially, narrowed posteriorly in basal 0.33 and then more rapidly in distal 0.66, posterior margin almost straight with median shallow concavity ( Fig. 61R ). Valvula I slightly dorsally curved, narrowed distlly, sculptured area occupying dorsal 0.5 width of valvula and distal 0.5 length, strigae oblique and sculpturing reticulate along dorsal margin ( Figs. 69 AB). Valvula II straight, narrowed distally, toothed area occupying distal 0.3 length, teeth prominent and widely spaced ( Figs 69 CD).

Material examined. HOLOTYPE ♂, NEPAL: Kathmandu , Bhandarkal, 30.ix.1978 to 3.iii.1979, V.K. Thapa ( UASB). Paratypes: 1 ♂, 1 ♀, data as for holotype ( UASB).

Remarks. This is a variable species as far as the extent of dark coloration on pronotum and face in the male are concerned and the females are paler. It has 3 subapical cells in the forewing as in the case of M. indica , but differs in coloration and structure of male genitalia. Male pygofer in M. thapai has more angularly pointed posterodorsal angle and has a ventral process whereas in M. indica the posterodorsal angle is rounded and there is no ventral pygofer process and the style has a group of thin long setae near apical region which are absent in M. indica . In M. thapai , the aedeagal shaft is straight for the most part and slightly curved anteriorly near apex whereas in M. indica the aedeagal shaft is curved gently right from the base.
