Ambadra montana Holloway

Ambadra montana Holloway, 1982 a: 206.

Suriga suriga Schaus sensu Holloway, 1976: 55, fig. 359.

Diagnosis

This is the largest of the three Bornean Ambadra, closest in appearance to suriga but with the red area basal to the forewing disc less prominent and the forewing overall slightly deeper, and redder in tone. The uncus is diagnostically apcurved in the male genitalia. Taxonomic note. Ambadra discocellularis Kiriakoff (Holloway 1982a: 207) from above 1000m in Sumatra (Bender & Dierl 1977) may be the sister species of montana if not related to suriga as suggested by Holloway.

Geographical range

Borneo.

Habitat preference

The species is montane, most characteristic of upper montane forest. It is frequent from 1500-1800 m on G. Kinabalu, common in upper montane forest on G. Mulu at similar altitudes and has been recorded singly under similar conditions on Bukit Pagon and Bukit Retak in Brunei. On Gunung Api, the limestone neighbour of G. Mulu, it was taken at 900 m in lower montane forest.
