Derambila livens

Diagnosis and taxonomic notes.
The original description refers to a light mouse grey and "quaker drab" insect with a spread span of 30mm, reflecting plumbeous in some orientation to the light. The forewing has the cell dot, rather small, the fasciae extremely faint, "suggested in brownish, antemedian not extremely outbent subcostally, moderately oblique; postmedian from about R2 onward very oblique inwards, slightly incurved, subterminal scarcely discernible". The hindwing is concolorous with the forewing, "cell dot rather larger but weaker, brown rather than blackish; a sinuous postmedian discernible in some lights" . The underside is similar if less strongly marked. Venation characters led Prout to associate the species with D. zincaria, D. dentifera and D. dentiscripta. The holotype male was in the Zoological Museum, Hamburg, and was probably destroyed by bombing in the 1939-45 war, so its identity is unclear. However, a male specimen taken recently by Dr John Willott in Sabah appears to match the original description in all but size (a span of 20mm), and is here taken to represent D. livens. It has typical Derambila genitalia (slide 17873).

Geographical range. Borneo.

Habitat preference. The holotype was from Sungei Matang. The recent specimen is from near the Danum Valley Field Centre in Sabah, both lowland localities, the latter forested, though logged.
