Arctornis camurisquama Collenette comb. n.

Leucoma camurisquama Collenette, 1932, Novit. zool., 38: 54.

Diagnosis

The forewings have a distinctively arcuate satiny white band just distal to the discal spot that stops well short of the dorsum and costa. The costa is also more reflective white, and the fringes are grey. The frons has a rich dark brown bar between the antennae, and the palps are a similar colour or only slightly paler. The legs are spotted. The male genitalia have the uncus small and narrow as in clavimicruncus, but the valves are more rectangular, with some subcostal lobing above the harpe which is straight or slightly sinuous, expandinggently into a rounded, club-like apex with sparse scobination over the distal third.

Taxonomic note

Bornean specimens attributed by comparison with the types to clavigeraToxopeus and, more tentatively, to linteola Toxopeus by Collenette in BMNH proved on dissection (slides 2132 and 2134 respectively) to have genitalia as in camurisquama.

Geographical range

Singapore, Peninsular Malaysia, Sumatra (Schintlmeister, 1994), Borneo.

Habitat preference

This is one of the commoner lowland forest species but is also frequent in lower montane forest at about 1000m. During the Mulu survey, it was taken mainly on the G. Mulu transect and was absent from kerangas and forest on limestone.
