Taviodes Hampson
Type
species: discomma Hampson,
Ghana.
This is
a mainly Afrotropical genus but has three described species in the Oriental
Region; Kobes (2005, Het. Sumatrana 12: 234-239) has described a third
species in Sumatra, T.
hollowayi.
Taviodes
appears
to be close in facies and abdominal features to the previous two genera,
particularly Bematha.
The male antennae are fasciculate. The wings are shades of medium vinous or
ochreous brown, though the type species is smaller and greyer. Some species have
males with the forewing apex falcate. The wings are fasciated with fine dark
lines, very irregular in the type species, but clearest and straightest in the
Asian species. The medial and postmedial are clearest, angled subcostally on the
forewing but more sinuous on the hindwing, as in the more diffuse submarginal of
the latter in several species. The forewing has a fine antemedial and a
bipunctate pale reniform mark. On the underside only the postmedials are
conspicuous and much straighter than on the upperside, except in the type
species where they are curved and irregular.
The male
abdomen has the eighth segment with vestiges of the framed corematous condition.
The tergite is broad, the apodemes splayed but well
separated; the sternite has lateral rods but only a
hint of an anterior lacuna. The genitalia have an uncus with an apical spur. The
valves are small but the sacculus usually has two distal processes that can be
long and digitate. There is a well developed saccus. The aedeagus is broad, the
vesica long, with two broad diverticula that bear distally either a mass of
needle-like spines, or sparse but often very coarse and occasionally tooth-like
scobination.
In the
female genitalia, the ostium is set in a shallow but broad pouch from the
anterior of the eighth segment. This pouch may be recessed under the reduced
seventh sternite. The ovipositor lobes and anal tube are typical for the Episparis
group.
The ductus is short, the bursa ovate to spherical, corrugated, usually with one
or two longitudinal scobinate bands in the distal part.
