Tamsia Roepke
Type
species: elegantula Roepke = hieroglyphica Swinhoe.
Kobes
(1985) tentatively associated this genus with the Serrodes
group
of genera. The mid-tibia has massive spining (Kobes, 1985), and the facies is
similar to that of some Avatha species. However, the black areas of the forewing are
more extensive basally, medially and submarginally as discussed in the species
account. The hindwings are more uniform above and show sexual dimorphism below,
those of the male being extensively suffused with black and with greater
curvature to
the costal margin. The male antennae are ciliate. The labial palps have the
second segment longer and the third much shorter (a fifth or less of the second)
than in Avatha
or
Serrodes.
The male
abdomen has the eighth segment of the framed corematous type.
The
sternite is somewhat compressed, shortened, and the corematous zone is narrow,
but lateral rods are present. The tergite is relatively broad. The genitalia
have a relatively long uncus; there is no scaphium. The junction of the tegumen
and vinculum on each side involves a structure that could be a paratergal
sclerite.
There is
a shallow juxta that resembles an inverted ‘V’, and the anellar tube, well
distal to it, is dorsally scobinate. The valves are densely inverted with setal
bases but the setae are deciduous. The valve apex is cleft, the part dorsal to
the cleft triangular, and that ventral to it narrow, produced into a tapering
process. The base of the valve costa extends as a loop into the diaphragma as in
Panilla
(p.
377, and see also p. 17). The aedeagus vesica is small but with a number of
short lobes and diverticula.
The
female genitalia have the ostium between the seventh and eighth segments, the
sternite of the former slightly reduced relative to the tergite; the distal
corners of the latter are slightly produced towards the margin of the sternite.
The ductus is long, narrow, sclerotised apart from a short membranous section at
one third. The distal section of sclerotisation is incomplete. The corpus bursae
is ovate, lightly scobinate, the ductus seminalis arising on a slight appendix
near a longitudinal band of denser scobination at its base.
The only
included species is described below.
