Chorsia
rufitincta Hampson comb. n.
Stenopterygia
rufitincta Hampson, 1918, Novit. zool.,
25: 129.
Diagnosis.
The shape and forewing markings are reminiscent of those of trifine noctuids,
the possible reason for Hampson’s original placement, but the hindwing
venation is quadrifine. The rather narrow forewings are dark brown, variegated
more rufous longitudinally and crossed by broken, irregular antemedial and
postmedial fasciae that have blue and white highlights, as does the reniform.
The hindwing is medium brown, paler than the forewing.
Taxonomic
note. This species was noted as misplaced in Stenopterygia
by
Holloway (1989: 147). The facies, though trifine-like, obscures a pattern that
is also consistent with placement in Chorsia,
as the male genitalia resemble those of C. octosema (see above) and C.
trigona Hampson
(S. India).
Geographical
range. Borneo.
Habitat
preference. The species was described from a single male from Sandakan on
the coast of Sabah. It has been recorded frequently in recent surveys, mostly
from various lowland forest types and more sporadically up to 900m.
