Liparopsis sundana sp. n.
Liparopsis sundana (paratype)
12-13 mm. The facies is as illustrated. The species is smaller than L.
postalbida Hampson (N.E. Himalaya, China, Taiwan), which spans 15--16 mm.
There are many similarities in facies but in sundana the patterns are
more clearly defined and there is a definitely darker tornal half to the
hindwing. L. dympna Schaus (Philippines) resembles sundana.
In the male genitalia the differences from postalbida are: the
juxta does not protrude beyond the saccus; the aedeagus apex lacks scobination;
the valve costa is sinuous rather than lobed; the valve apex is curved upwards
rather than straight; both ventral processes of the valve are sclerotised, spine
like, rather than just the distal one, which is subapical rather than central.
In L. dympna the uncus is square-ended, the ventral process of the valve
acute as in sundana, but the central process is enlarged, rounded, fused
with the costa, eclipsing the valve apex which is exterior to it.
