Abstract:
Simulium (Gomphostilbia) ogatai (Rubtsov) from Japan, the only Palaearctic species in the S. ceylonicum
species-group, is morphologically revised. Its female is described for the first time and its male and
pupa are redescribed based on specimens from Gifu, Honshu. It is characterized in the female and male
by the base of the radius with a tuft of yellow hairs, in the female by the head slightly wider than the
thorax, 5.89 times as wide as the greatest width of the frons, and short sensory vesicle 0.21–0.24 times
as long as the third palpal segment; in the male by the number of upper-eye (large) facets in 15 vertical
columns and 16 horizontal rows, and hind basitarsus spindle-shaped, enlarged, 3.79 times as long as
wide, and 0.83 and 1.00 times as wide as the greatest width of the hind tibia and femur, respectively;
and in the pupa by the terminal hooks simple and cone-like, and the cocoon with an anterodorsal
projection. Taxonomic notes for this species are given relevant to several related species in the Oriental
Region, and its assignment to the S. ceylonicum species-group is confirmed.
