Ectropidia quasilepidaria sp. n.
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.
