Ectropidia quasilepidaria sp. n

Ectropidia quasilepidaria

11-13mm. Externally this species is indistinguishable from E. illepidaria. There are constant differences in the male and female genitalia, however. In the male abdomen, there is a robust pair of coremata between segments 6 and 7, but quasilepidaria is distinguished by possession of small, slightly corematous lobes just anteriorly on segment 7. Both species have a curved spine on the saccular process and a straight one centrally on the ventral margin of the valve: the former is larger than the latter in illepidaria, but the reverse holds in quasilepidaria. The aedaegus vesica is more strongly scobinate, correlating with a shorter, broader neck and bulb to the bursa copulatrix, the neck being basally more scobinate.
