Here's a Nacaduba from today... it is quite faded. Is it possible to ID this one?
ID as Nacaduba subperusia lysa

WOW Jon it looks like N. subperusia lysa, which would be a rediscovery. Notice the post-discal series on the hindwing is very straight and practically touching the submarginal series; the gap between is smaller than all the others in the pavana group. The submarginal striae, in stark contrast, are much more rounded than the striae immediately basad to them.
Where was this taken?
Aaron Soh
This was taken in usr! The upperside was a dull purple if I remember correctly..

Thanks Aaron and Dr Seow for the ID input! It is very likely to me that all our original Nacaduba species are still extant, just that they may have been either ignored or mis-identified in the past. It doesn't help that most of our encounters with them are fleeting, flying-by sightings. I often see them fluttering high above the ground in the treetops.

Here are a few more Lycaenids...
In my view, the 6-line Nacaduba species can be more confusing to separate than the 4-line ones. I've attempted to identify them based on what I've read from previous posts. Dr Seow, Aaron, what do you think?
1) Nacaduba berenice male
2) N. beroe male
3) N. beroe male
4) Nacaduba beroe female
Arhopala. epimuta male

Post 10.
1.Male Nacaduba berenice.
2, & 3. males N. beroe
4. Female N. beroe.
5. Arhopala epimuta.
The 6line Blues need to be identified by the sex first.
Male ;FW apex blunt,termen fairly straight; abdominal end truncated & brush like.; palpi short (not reliable)
Female ;FW apex pointed follow by a convex termen. abdominal pointed without a brush. Palpi longer but confusing in photos.
Male 6Line Blues.
A. Dark striae strong .
A1, N berenice; FW postdiscal typically broken in the middle ;submarginals irregular.
A2, N. calauria ;FW postdiscal almost always straight & unbroken; FW submarginal spots 4 & 5 sharp pointed.
B. Dark striae weak/moderate to obsolete.FW termen always rather straight.
B1. N. beroe : FW innermost (costal spot 12)absent; postdiscal band broken in the middle ;lower 3 submarginal rectangular; wingbase darkish.
B2; N kurava ;FW costal spot 12 always present; postdiscal usually fairly straight , not broken; submarginal often broad with rounded margins; wingbase not dark.
Female 6Line Blues.
All females have strong dark striae.
Female .N. beroe 'FW costal spot 12 absent or vestigial. FW postdiscal broken (variable) in the middle.
Female N. kurava;FW costal spot 12 present; FW postdiscal usually straight; submarginals large with rounded margins.
Female calauria. FW costal spot 12 present; postdiscal straight & unbroken; submarginal spots 4 & 6 sharp-pointed.
Female N berenice; FW costal spot 12 present; postdiscal usually partially broken in the middle; submarginals irregular; spot 4 & 6 not sharper than the others.
eg N. calauria male on the left, female on the right.

Quite right all.

Concur it is N. subperusia lysa.
N. sanaya can sometimes cause confusion but the FW postdiscal band is always distinctly dislocated at vein 6.

The other similar one which normally is commoner is N. hermus swatipa.
N. hermus swatipa.
FW postdiscal band not or barely dislocated at vein 6.
Dark striae often weakly present.
HW tornal black spot almost always with some metallic blue scales.
