Chrysocraspeda pryeri sp. n.
8-9mm. In facies this species resembles C. mitigata Walker,
discussed next, but differs in several features of the male genitalia. It
resembles the type material of mitigata more closely than does Bornean mitigata
in facies, as the grey zone of the hindwing is much closer to the margin
over the tornal half than it is over the apical half (of more or less even width
in Bornean mitigata). However, the male genitalia indicate that the more
broadly bordered specimen is true mitigata whereas the others are
distinct. The features are: an almost straight valve spine (more slender and
curved towards the apex in mitigata): a narrower uncus; a broader apex to
the aedeagus, coarsely spined on one side, opposite a process like a short
knife-blade. In the last feature, the most consistent difference, it resembles C.
