Tanaorhinus rafflesii

This and the next species are very similar, distinguished by Holloway (1982). T. viridiluteata Walker has a broad, uniform, reddish brown border to the male hindwing below, whereas in rafflesii this is narrower, distally bidentate, separated from the margin by a yellow zone. Females of both species approximate to the former state and cannot be distinguished on facies. The forewing underside is more heavily marked and suffused with brown and mauve in viridiluteata. In the male genitalia the harpe is shorter in rafflesii, apically acute rather than spatulate.

Geographical range. S. Burma, Sundaland.

Habitat preference. This and the next species have been recorded in forest localities from the lowlands to 2600m, but their dual identity was not appreciated when these collections or counts were made. Where voucher material is available, it would appear that rafflesii is the commoner particularly on lowland localities, and that viridiluteata is recorded more frequently in montane forest. The new montane species described by Yazaki (1995) are similar in appearance to. viridiluteata.
