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.

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.

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

The markings are as for the muta subgroup (amphimuta group)
Probably A. muta.

Two species in the same subgroup formerly recorded in Singapore are very difficult to separate .

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.

On the HW inner margin one of the white stria forms a sharp spike indicating a Jamides.
The FW postdiscak band is dislocated at every vein.

Nacaduba hermus male.
The four line blues can be rather difficult to ID.

N. pactolus can be IDed by the combinations.
HW tornal black spot always with metallic scales.
white striae often broad or diffuse,dark striae absent.
HW submarginal spots 'flat' with level inner margins, topped by a large squarish spot 6.

https://www.butterflycircle.com/chec...0-%20Sunny.jpg

Species with the dark strae obsolete or nearly so.
N. sanaya, subperusia, & pendleburyi.

Species with strongly developed dark striae, tornal spot always with metallic scales.
N. pavana, russelli.

Species with heavy white striae and metallic scales on the tornal black spot.
B. pactolus, angusta.


Nacaduba hermus is uniquely halfway between those with strong and those with no dark striae.
Dark straie are patchy , partial or disintegrating.
The metallic scales on the tornal black spot may be weak or strong.
FW postdiscal band usually not dislocated at vein 5.
HW postdiscal band close to the submarginal spots which may be rounded.
