18-21mm. The wings have an even (or stronger at the tornus) row of minute
dots on the vein ends at the margin, though these are absent in some specimens
and less evident on the hindwings. In the male abdomen the eighth sternite is
narrow with lateral coremata and the tergite is broad, short, with a transverse
central lacuna. The valves are narrow, tapering over the apical half as in tibialis
Fabricius, but are not much longer than the tegumen rather than extending
well beyond it; tibialis lacks coremata. The juxta has lateral horn-like
processes as in tibialis. Coremata are otherwise only seen in C.
basiflava Holloway and in a taxon from Java (slide 14220) where the uncus is
more sinuous, the valves much broader, not tapering, and the juxta considerably
smaller.
