Strand
comb. n.
Leucoma
singaporensis Strand,
1914, Gross-Schmett. Erde, 10: 310.
Diagnosis. The wings are an opaque, faintly creamy white, the forewings with a
greenish tinge to the veins in the central area. The frons and palps are
entirely rufous brown though they grade paler ventrally, and the forefemur and
upper part of the foretibia also have extensive areas of this colour. The male
genitalia have a narrow, setose, spearhead-like uncus arising from a
semicircular base. The valves have an angle at the centre of the costa, and the
harpe, somewhat extruded from its saccular pocket in the illustration, expands
for one quarter then tapers for three-quarters to a small, bulbous apex: there are
conspicuous setae dorsally on the tapering portion and apically.
Geographical range. Sundaland.
Habitat preference. Specimens have been taken infrequently in recent
surveys, but all are from lowland heath and alluvial forests as well as
mangrove.
Biology. There are two host records from Peninsular Malaysia: Shorea (Dipterocarpaceae)
in unpublished FRIM records; Medinilla (Melastomataceae) for a female
reared by H.S. Barlow.
