25-27mm. The species resembles B. undulosa in general facies but the wing markings are dull, ochreous, pale brown,  rather than grey, also the thorax; the pale area of the hindwing is more extensive.

In the male genitalia the valves are basally narrower than in undulosa and thus more evenly tapered overall. The cubile arms terminate in an angled, rather than rounded, sclerotisation. The ventroapical spur from the aedeagus is larger and more evenly curved and tapered.

Geographical range. Borneo.

Habitat preference. During the Mulu survey six were recorded from montane forest on the limestone G. Api and six from regenerating alluvial forest in the lowlands. The Brunei specimens were from dipterocarp forest.

Biology. This is not known but possibly similar to that described for B. undulosa in the generic account.
