11mm. The general appearance
is similar to that of “Eilema” pulvereola Hampson (see “Eilema” pulvereola Hampson) but
without the darker margin on the forewing underside. The forewing cell is the
same length as in pulvereola, but the distal veins are more widely spaced,
with the radial sector branching system being (R3 (R4, R5)) as in all “Tigrioides”
species. The male genitalia are highly atypical of Tigrioides or Eilema,
being short, broad, with broad valves fused along much of their saccular
margin, and with similarly short, broad saccular processes. The uncus is short,
set on a broad, triangular base that is fringed with setae. The aedeagus is
narrow with an apical spur, and the vesica, also narrow, tapers into a narrow
diverticulum with small spines at its apex. These male genitalic features are
seen also in "T" aurantiaca Hampson (Philippines), a smaller,
yellower species with valves that are more angled, less rounded apically. The
female has pouches laterally on the seventh segment, a ductus that is expanded
and sclerotised on one side over its basal half, and an ovate bursa with two
quite extensive scobinate, nipple-like signa amid more general weak scobination
and concentric wrinkles.
