Beara castanea Moore, 1879, Descr. new Indian lepid. Insects Colln W.S.
Gelastocera castanea Moore; Kobes, 1997: 78.
Diagnosis. The species bears some resemblance to Arrhapa
(p. 129) in the rather uniform, irregularly fasciated forewings, but these are
browner, less pink, and the submarginal row of dark dots is irregular in course,
not distinctly triarcuate. The male antennae are bipectinate as in other members
of the Gelastocera complex.
Taxonomic note. Sundanian material has slightly different ornamentation to
the sock-like aedeagus vesica: the spines in the cluster at the apex are
smaller; the more basal small cluster of the typical race is absent.
Geographical range. N.E. Himalaya; Sundaland.
Bornean material is limited to a single female
from 400m in dipterocarp forest, Ulu Temburong, Brunei.
