Diagnosis. Males of this and the next species (See Dasyboarmia
pilosissima sp.n) have the wings a uniform
dark tone. The females (isorrhopa only known) are strongly variegated.
The last two species discussed here are smaller, the males with some variegation
to the pattern.
Taxonomic notes. This and the next species are closely related and rather distinct from
the Sumatran D. hyperdasys Prout and the Philippines D. owadai Sato.
Shared features of the male genitalia include: modification of uncus and
gnathus into a pair of erect, equal or subequal spine-like processes; asymmetry
of the valve costal processes, the left outcurved, the right shorter, broader;
possession of a zone of dorsally directed setae along the ventral margin of the
valve.
In D. hyperdasys the costal processes are symmetrical with a
spine-bearing, slender, interior process, the uncus is normal, and the aedeagus
has very large cornuti. The abdomen has small coremata laterally distally on
segment 7.
Geographical range. Borneo.
Habitat preference. The species has only been recorded from G. Kinabalu,
where it occurs from 1200m to 2600m, and the adjoining Crocker Range (FRC,
Sepilok, collection). It was found to be particularly abundant just below 2000m.
