Throana klossi Prout

Throana klossi Prout; 1932, Bull. Hill. Mus. Witley, 4: 286.

Diagnosis

See Throana callista Prout. The hindwing has a particularly acute marginal angle; its band of arches is much broader centrally, the submarginal itself being more strongly lunulate. There is usually a conspicuous, paler grey patch distal to the dark triangle on the costa adjacent to the angle of the postmedial.

Geographical range

Peninsular Malaysia, Borneo.

Habitat preference

The five specimens seen from Borneo are all from lowland forest: two from Semengok near Kuching; one from 100m on G. Santubong, also near Kuching; one from Labi (30-60m) and one from the Ulu Temburong (300m) in Brunei.

Taxonomic Note

A larva of a Throana species, probably klossi, was reared from Neolamarckia (Rubiaceae) by Chung et al. (2009a) and illustrated, together with a freshly emerged adult. The larva is very slender, bright green, with a pair of narrow dorsolateral lines running almost the whole length of the body. The anal prolegs are long, splayed out behind. Some fine black dots are present on the thoracic segments.
