This and the next two species have a much more ashy grey forewing ground colour
than the ones described above, and have conspicuously darker markings associated
with the forewing submarginal: in pertendens and
the next species, these are restricted to the apex near the tornus in both
sexes. The postmedials of all wings are usually darkly punctate, and the
forewing reniform is relatively small and usually edged darkly.

preference. The species appears to be uncommon in Borneo, only known from
singleton males from the Danum Valley Field Centre (forest edge at 100m) and
dipterocarp forest at 250m on the slopes of the limestone G. Api.
Miyata (1983) and Sugi (1987) noted that the larva fed on Berchemia
(Rhamnaceae); Robinson et al. (2001) recorded Cassia (Leguminosae)
for a species tentatively identified as pertendens by
the author (unpublished IIE records) from the Andamans.
