Male Abisara geza.

Male is IDed by the rounded margin at HW vein 4, while female have a pointed 'tail'.
Both species varies in the dislocation at vein 4.

A. saturata. Tornal black spots pointed, teardrop shape.HW discal line usually not dislocated at vein 4.

Male ;FW with two parallel pale postdiscal bands not enhanced white & one submarginal white line.

1. Probably Pantoporia sandaka female.

You can see the abdomen is bulging & the FW foot of the postdiscal band is short.

Although the grey band is wide suggesting P. hordonia, the orange submarginal band is enhanced at the apex as in most P. sandaka.
It is no dofferent from this female.

More typical Male & female P. sandaka from Singapore ie with narrow grey band.

You need to shoot a male from the same place.



2. Female Potanthus serina.
Abdominal end with a black band (less clear in the female)
FW spot 5 smaller than spot 4; HW ground brown dusted ;band with a small spot 6 on inner edge.
FW spot 8 may be small.

Thank you Dr Seow!

So far all males taken in Singapore can only be identified as Pantoporia sandaka.

Hi Dr Seow,

I have been trying to figure out the key ID features for the pavana group Nacadubas, but with not many images available online of live specimens, some of them have been rather challenging, especially N.pendleburyi and N.solta. Would it be possible for you to do an overview of the key IDs? Thank you.

These are some features I have noted/read, splitting the group into 2, with and without metallic scales in the tornal spot.

With metallic scales:

1. N. pactolus
- FW post-discal band typically straight
- Submarginal spots quite rectangular
- HW submarginal spot 6 large, spots 4 & 5 flattened.

2. N. hermus
- FW post-discal band typically straight
- FW submarginal spots chevron shaped
- HW post-discal band in spaces 4 & 5 very close to HW submarginal band

3. N. pavana
- FW post-discal band typically straight, sometimes with dislocations
- Prominent white 'bar/band' running through submarginal spots
- Marginal spots bar-like

4. N. russelli
- Marginal spots oval/lozenge-shaped
- Outer margins of submarginal spots pointed

5. N. angusta (should be distinct enough)
- Broad and diffused whitish striae
- Strongly contrasting black submarginal and marginal spots
- HW submarginal spot 6 large and rounded

Without metallic scales:

1. N. sanaya
- FW post-discal band typically dislocated at vein 6
- HW post-discal band well separated from HW submarginal band

2. N. subperusia
- FW post-discal band gently curved but not markedly dislocated towards costa
- HW post-discal band in spaces 4 & 5 very close to submarginal band (almost touching)
- HW submarginal spots strongly concave and dark, contrasting greatly from ground colour

3. N. pendleburyi
- FW post-discal band gently curves towards costa
- HW post-discal band well separated from HW submarginal band

4. N. solta
- FW post-discal band straight
