Figs 25A–G , 61K , 67E–H .

Idioscopus pretiosus Viraktamath 1979a: 20–21 , figs 13–19.

Diagnosis. Crown and pronotum lemon yellow, lateral margins of pronotum pale brown. Antennae with subapical black disc in male. Forewing brownish with one black round spot on third apical cell. Male pygofer with dorsal apodems on anterior margin, anal collar process elongate, pointed, pygofer posterodorsal angle angular, without ventral process. Style apophysis with subapical row of long setae on dorsal margin, ventral margin serrate. Aedeagus with well-developed dorsal apodeme, shaft curved dorsoanteriorly, with pair of short subapical processes directed anteroventrally, gonopore apical, dorsal margin of shaft feebly serrate.

Description. Female. Sternite VII convex, about 2.2× as long at base as long medially, with slight concavity in middle on posterior margin ( Fig. 61K ). Valvula I broad at base, narrowed distally, sculptured area occupying about distal 0.6 length, strigae short, occupying not more than 0.3 dorsal width of valvula, slightly oblique ( Figs 67 EF). Valvula II straight, gradually narrowed distally, toothed area occupying distal half length, not very prominent, teeth small close together ( Figs 67 GH).

Material examined. HOLOTYPE ♂, INDIA: Karnataka: Mudigere , 22.v.1976, C.A. Viraktamath ( UASB). Paratype, 1 ♀, with same data as for holotype ( UASB).

Remarks. Virktamath (1979a) adequately described and illustrated this species. This species externally resembles Bellacerus bellus in coloration but differs in the structure of the male genitalia and also in having two short anteroventrally directed subapical processes on the aedeagal shaft (aedeagal shaft without processes in B. bellus ).
