Hyposemansis Hampson
Type
species: singha Guenée,
Bangladesh.
This
genus is probably best restricted to its type species. None of the species
listed by Poole (1989) appears to be compatible. The species lasiophora Hampson and mediopallens
Wileman
& West are transferred to Pangrapta Hübner below, and xyrina
Kobes
is a synonym of Focillistis sita Felder & Rogenhofer (p. 300).
The
facies and wing shape are as described in the species account below. The male
antennae are ciliate. The labial palps long, upcurved as in Pangrapta.
The
eighth segment of the male abdomen is of the framed corematous type. The
genitalia have simple valves that are invested throughout with fine hair-setae.
There is an oblique pleat basally that separates off the saccular region, but
otherwise there is no ornamentation. The tegumen and vinculum have a complex
articulation that may involve a paratergal sclerite. There is a moderate saccus.
The aedeagus is large, finely grooved apically, with a vesica that is large,
convolute and generally scobinate, but lacking the cornuti seen in many Pangrapta.
The
female genitalia have the ostium between the seventh and eighth segments; the
sternite of the former is only slightly reduced, and the latter consists of an
incomplete ring with setae only on the posterior margin. The ductus is narrow,
unsclerotised. The corpus bursae is large, irregular, generally finely scobinate
and distally weakly corrugated. The ductus seminalis arises from one side in the
centre, rather than near the base, a feature seen in some Pangrapta
such
as albiseriata
Hampson.
