2.7. Centroptella (Crassolus?) sp. « Nepal »

( Figs 422–428 )

Material examined. Central NEPAL, Helambu Area , 27°55’N 83°30’E, Gohare Khola opposite to village Mahenkai, about 500 m from falling to Melamchi River, 4.III.2007, coll. M. Chertoprud: 1 male larva of penultimate instar (other specimens in Chertoprud’s collection) .

Distribution. Nepal.

Comments. Characters of this larva are reported in the Table 3 and shown on the Figs 422–428 ). Pose of developing subimaginal gonostyli is unknown; judging by the presence of denticles on posterior margins of abdominal terga II–X and the presence of setal rows on abdominal sterna III–VI, this species probably belongs to Crassolus .
