Chrysocraspeda pryeri sp. n.

Chrysocraspeda pryeri
(x 1.33)

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. orgalea Meyrick.
