Diagnosis. The ground colour is pale yellow, the forewing lightly irrorated with
blackish scales except at the margin, and the hindwing entirely dark grey except
for a yellow border bounded diffusely with the grey. On the underside, both
wings are basally grey, with a broad yellow border.
Taxonomic note. The male genitalia have the generic features, though the saccular flap
is short, broad, with a central acute process. The valves have two spurs at the
ventral margin. Schintlmeister (1994) referred material with similar genitalia
(but with the outer valve spur distinctly larger) to flavocinerea van
Eecke. The facies is similar, though the Sumatran material illustrated appears
worn or faded.
The true identity of flavocinerea (Sumatra) is somewhat
different. It is a pale fawnish species with male genitalia (Fig 97) very
different from vespertilionis but nevertheless also having Orvasca features,
so it is transferred to the genus, comb. n. The male genitalia have an
uncus and gnathus structure typical of Orvasca, though the latter is only
lightly rugose. The valves are divergently bifid. The flap between the valve
bases consists of two widely separated spines.
Geographical range. Borneo, ?Sumatra.
Habitat preference. The holotype of vespertilionis was taken in
the same locality as that of rufalba. No further material has been seen.
