Scrobigera
hesperioides Walker stat. n.
Eusemia hesperioides Walker, 1862, J. Linn, Soc. Lond. (Zool) 6: 86.
Scrobigera proxima hesperioides Walker; Kiriakoff, 1977: 37.
Diagnosis.
The species
is somewhat similar to Crinocula kinabaluensis Rothschild but is larger,
with forewing apices more produced. The forewing band is almost complete rather
than restricted to the centre of the wing, and the fringes of both wings are at
least partially white.
Taxonomic
notes. The
extent of orange on the hindwing is very variable, as is that of the white
fringes. S. proxima Walker has a more irregular, often broken postmedial
band to the forewings and an additional short bar distal to it. The valve of the
male genitalia in proxima has the valve costa straight, the apex acute,
and the valve narrows evenly to the base, rather than being sharply constricted
subbasally. The harpe in proxima is more slender, longer, and less evenly
curved. These differences indicate the two taxa are best distinguished as good
species.
Geographical
range. Borneo.
Habitat
preference. The
species has been noted mainly from lowland forest.
Biology.
The species
is day-flying. The larva of proxima (as amatrix Westwood) was
illustrated by Horsfield & Moore 1858-9 (plate 8: 2). The head, prothorax
and anal segments are yellow with black spots. The rest of the body is black
with white subdorsal bands and intersegmental rings. The primary setae are long.
The host-plant was Cissus (Vitaceae).
