Inner costal spot above the mid cell band present.
Male.

Nacaduba kurava.
Male with weak dark striae & FW margin rather straight.
FW postdiscal band more often unbroken.
FW submarginal spots with rounded margins.

The female beroe is very similar & confused with the female of Ionolyce helicon.
In I. helicon HW submarginal spot 3 (above the black spot 2) is sharply pointed.
In the female of N. beroe this spot is rounded.

Female Caltoris malaya.

The spots here, subapical spots 6, & 7 and a larger spot 4 is seen typically in Caltoris.
There is also no indication of an upper cellspot present.

In Polytremis lubricans, there are three subapical spots usually & spot 4 is no bigger than the subapical spots.
Wear have cause a coarse overlay appearance.

See female from Yala.

Navaduba berenice.
The male on the left have the typical features, 1.Strong dark striae. 2. crooked FW postdiscal band .& 3. a costal spot above the midcell band.




2. https://www.butterflycircle.com/atta...6&d=1742125455
The markings are as for the cleander group ,as the HW submarginal & postdiscal band are well separated should the larger-sized cleander subgroup.
Two species in Singapore ,A. athada & silhetensis.

This should be A. athada.
HW spot 6 bridged the gap between spot 5 & the cellend bar.
https://www.gbif.org/occurrence/2847199362
https://www.gbif.org/tools/zoom/simp...56f61a96ee3b43

A. sihetensis is very large with widely separated markings & spot 7 sinuous & spot 6 free-hanging.

3. https://www.butterflycircle.com/atta...7&d=1742125479
The markings are as for the muta subgroup (amphimuta group)
Probably A. muta.
https://www.gbif.org/occurrence/2847202887
https://www.gbif.org/occurrence/2847201904

Two species in the same subgroup formerly recorded in Singapore are very difficult to separate .
https://www.gbif.org/occurrence/2847202884
https://www.gbif.org/occurrence/2847200390

A. antimuta can be rather similar but the spots are more angular, spot 7 is atop spot 6 usually and the green metalmark is flatter, with smaller black spots.
