Abstract. Coiiaspidia maculosa, new species, is described from Sikkim, India. It is
the fourth species of this Asian genus known from India, the other species being C.
clubiosa Forsius, C. fasciatipennis Turner, and C. sikkimensis Konow. The new species
belongs in the scuteUaris group of Coiiaspidia and is separated from related species in
that group and the other Indian species.

Coiiaspidia Konow is an exclusively large spot lateral to postocellar area; small

Discussion. This species belongs tothe
scutelloris group of Wei and Nie (1997).
The sciitellaris group includes C. liiiiuitci
(Matsumura 1912) from Japan, C. kuhipan-
acis Xiao and Huang 1983 from China. C.
liiii Wei 1997 from China, C. miirotai To-
gashi 1984 from Japan, and C. scitteUahs
