Abstract:
The Simulium gombakense species-group, one of the 15 species-groups of the subgenus
Gomphostilbia Enderlein, is small, being represented by only 12 species, all of which are
distributed in the Oriental Region. It is characterized by the pupal gill composed of an
inflated structure and eight or ten slender filaments. Among the 12 species, S. sachini Takaoka
& Henry, and S. williei Takaoka & Thapa were originally described from two pupae, and one
pupa and two larvae, respectively, from Darjeeling, India. In the present paper, the adult
females and males of these species are described for the first time from specimens reared
from pupae collected at the type locality. Simulium sachini is distinctive in the female by the
claw with a medium-sized basal tooth, and in the male by the somewhat enlarged, spindleshaped hind basitarsus and ventral plate with its ventral margin much depressed medially,
while S. williei is characterized by the small number of male upper-eye (large) facets in
12 vertical columns and 13 or 14 horizontal rows and ventral plate much produced
posteroventrally. Taxonomic notes are given to separate these two species in the adult
stage from their related species.
