Type species: dholaria Moore, N.E. Himalayas, China, Japan.
The genus contains a number of large, brown, Oriental species. The wings
are generally brindled or striated, and the forewing usually has a broad,
irregular, whitish bar just distal to the centre of the costa, running obliquely
to the dorsum, the inner edge stepped outwards along CuA1.
The male has a small but distinct fovea, no setal comb on sternite 3,
and bipectinate antennae. The female also has bipectinate antennae but the
pectinations are shorter.
The male genitalia are robust, the valve typically boarmiine with a
broadly setose cucullus. The type species has a triangular projection from the
interior of the sacculus, lacking in the Bornean representative. The uncus and
gnathus are robust, the former triangular, apically truncate or bifid. The
aedeagus vesica has a scobinate or spiny patch and, in the type species but not
the Bornean one, a single, strong, basal cornutus.
The female genitalia have the ovipositor lobes oval-rectangular, darkly
sclerotised, though with paler halves to the setal bases. The apodemes are long,
slender, straight. The ductus is short, conical, the bursa narrow throughout,
with a small, irregularly dentate, distal signum. The anterior margin of the
rather elongate eighth tergite is rounded or slightly bilobed.
The larva of the type species was illustrated in Sugi (1987). It is leaf
green with a fine, straight, yellowish dorsolateral line. The spiracles are
picked out dark in a small yellow halo. The thoracic segments are slightly
tumescent when the larva is at rest.
The host plant, as for the Bornean species below, is Lindera (Lauraceae).
