Hypopyra ossigeroides Holloway sp. n.

♂♂, ♀ 38-43mm. This is a generally darker species than the previous one, with extensive pale mauve irroration, particularly concentrated in the zig-zag fascia between the postmedial and submarginal, though not as strongly as in the next species, which also has the postmedials much closer to the dark medial fasciae. There is strong brown shading grading distad from these medial fasciae and also basad from the distal margins. As in ossigeraand other species discussed under pallidigera, the forewing discal black patch, when enlarged, has a curvature with its concavity directed towards the apex of the wing. The two females seen are darker and have the forewing black pitch vestigial. In the male genitalia the uncus is similar to that of ossigerabut the valves are shaped more as in pallidigera, though with a more evenly curved apical margin. The transverse flange of these two species is reduced, but replaced by a large, thumblike process.

Taxonomic note

The taxon padanga Swinhoe from Sumatra is based on a male and a female. The male resembles, and is probably synonymous with, vespertilio. The female resembles a worn specimen probably of ossigeroides from G. Api mentioned below, where only the wings were retained. As species identities in the genus are best established on male specimens which tend to be commoner, the male syntype of padanga is hereby designated LECTOTYPE, and the female syntype is associated with the male material of ossigeroides. Kobes (1985) did not refer to padanga but illustrated specimens of vespertilioas ossigera, later noted and rectified (Kobes, 1992).

Geographical range

Borneo, Sumatra.

Habitat preference

This is a rare species of montane forest, with all specimens taken at 1500m or above. In addition to the material listed, a fourth specimen, a female, was taken at 1500m in an area of open scrub and Pandanus on the limestone G. Api.
