Scopula asymmetrica sp. n.
8-9mm. This is a medium sized, rather grey brown species with strongly
bidentate postmedial fasciae, distal to which are similarly irregular and rather
broad submarginal grey bands. In facies the species bears similarities to S.
limbata Warren (Taiwan), S. ophthalmica Prout (Sulawesi) and S.
ocellata Warren (Sumatra, Java), but the last two are smaller, much more
strongly marked, and all have the forewing discal spot blackish: in asymmetrica
it is the same grey as the fasciae. The extreme asymmetry of the valves of
the male genitalia is diagnostic, seen much more weakly in ophthalmica and
ocellata (left valves half size of right rather than vestigial).
