sobana Kobes, 1989, Heterocera Sumatrana,
2: 178.
Diagnosis.
This is a much more uniform pale brown species than capatra,
with the narrower pale area of the forewing reniform conspicuous and its
postmedial more clearly angled. The orbicular has a conspicuous dark dot just
exterior to the curved pale antemedial. On the hindwing, the sides of the
postmedial angle are slightly concave distad, and it shares with the next
species a diffusely darker brown subbasal patch. The male gentialia are
diagnostic, however, identical to those of capatra, so it is possible that the two taxa represent one
dimorphic species. The figures in the original description were numbered
wrongly, those of sobana being fig 16 (See also Heterocera
Sumatrana 12: 224 (2004)).
Geographical
range. Sumatra, Borneo.
Habitat
preference. Three female specimens seen are from 85 miles above (upstream
from?) Pontianak in Kalimantan, probably a lowland locality.
