Diagnosis.
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.
