Distribution. Korea, Japan, China, India, Thailand, Malaysia, Java.

Remarks. The identity of this species is taken from Kwon 1980 who described and figured specimens from Korea, the type locality. Kwon stated that the species could be distinguished by the larger head spots and different male genitalia, i.e. the truncate aedeagal apex with processes subapical. Kwon presumably arrived at his identification of terauchii based on Matsumura’s description that included a figure of the female holotype showing round head spots. All specimens examined have the vertex spots more rounded than in most ceylonensis and facial spots larger (but see Remarks under ceylonensis ). Both these species have similar distributions and are sympatric in Nepal (Jiri) and possibly other areas as well.
