Hexamitoptera Pagenstecher
Type
species: lawinda Pagenstecher, Sumatra.
Synonym:
Poeciloptera
Pagenstecher
(type species lawinda) praeocc.
The
facies resembles that of Hypopyra though the wing shape is different as
described and illustrated below for the only species.
The male
abdomen has the eighth segment unmodified except for a very shallowly bilobed
posterior margin to the sternite. In the genitalia, the uncus is modified into a
striking horse-head shape, and the tegumen has small, thorn-like processes on
each side. The valve is relatively short, cleft into two processes distally, the
costal one longer and more complex. The juxta is of the inverted ‘Y’ type,
extending dorsally as a pair of acute processes flanking the anellus. The
aedeagus is slender, strongly curved, its vesica very small.
In the
female genitalia, the ostium is at a narrow cleft in the slightly bilobed
posterior margin of the seventh sternite which is otherwise not particularly
reduced relative to the tergite. The ductus is long,
slender, irregularly curved and distally fluted, with the ductus seminalis
arising from near the ostium. The corpus bursae is pyriform and densely but
finely scobinate throughout.
