Condate
orsilla Swinhoe
Diomea
orsilla Swinhoe, 1897, Ann. Mag. nat. Hist. (6),
19: 169.
[Capnodes
snelleni Semper, 1901, Reise. Phil. Schmett.,
2: 587; see taxonomic note].
Diagnosis.
See the generic account. The species is very similar to hypenoides
and
pseudohypenoides,
but is dark brown rather than dark grey but with similar fasciation. However,
the submarginals are more regular and linear, and the forewing postmedial does
not extend so far basad along the costa from its subcostal angle, and, with the
antemedial, lacks the blackening at the costa that characterises hypenoides.
The forewing reniform is more broadly blackened.
Taxonomic
note. Semper (loc. cit.) illustrated two specimens from Luzon
that he attributed to orsilla
and
a new species, snelleni Semper. Probably neither is conspecific with orsilla.
The former appears to have a much more variegated forewing and the latter has
both the forewing antemedial and the submarginal straighter than in orsilla.
Geographical
range. Singapore,
Peninsular Malaysia, Borneo, Philippines.
Habitat
preference. This is a rare species, mostly taken in the lowlands. Three
specimens are from the Pontianak locality as for the previous species. One is
from 150m in mixed dipterocarp forest on G. Mulu and one from primary lowland
forest at 170m near the Danum Valley Field Centre in Sabah. However, one is from
900m in lower montane forest on the limestone G. Api.
