Diagnosis. The species is smaller than all congeners except L. prouti Debauche.
The male is a uniform medium grey, paler than Calletaera schistacea Swinhoe,
but with similarly dark fasciae; the hindwing is more strongly crenulate. The
underside is darker grey, more or less uniform. The female has the basal half of
both wings paler, more conspicuously so on the underside. In both sexes pale
submarginal markings on the underside are restricted to subapical sagittate
marks in the male and a more continuous row in the female.
Taxonomic notes. The species probably does not occur east of Sundaland. L. celebensis Prout
stat. n. is probably the sister-taxon, but has narrower uncus and a very
short, quadrate subapical flange to the ventral arm of the valve. It is best
regarded as a distinct species. Also in Sulawesi flies L. paganata Felder
& Rogenhofer (L. leithra Debauche is probably a synonym) where the
subapical flange is extremely large. Further taxa of the complex are found in
Seram and New Guinea.
Geographical range. N.E. Himalaya, Sundaland.
Habitat preference. The species is common in lowland and lower montane
forest, and is also recorded infrequently from the upper montane zone.
