ID help needed

Hi Dr Seow, thanks for the id.
Yes, the skipper was taken in S'pore.

Hi Aaron,
A. reta was taken inside Mandai forest.

The three other Potanthus species in Singapore all have FW spots 4 & 5 of equal size & abdominal end almost wholly yellow in the male.(female may have a bit of dark dorsal shade.)

P. omaha males.

It might just be P. juno male.
Sometimes on the underside FW spot 8 is partially present, but on the upperside fully missing, as seen in this shot.

2. is female Erionota acroleuca.
Note the name is now correctly back to E. acroleuca instead of E. hiraca.

In female E. acroleuca the HW patch is much wider in the lower half.
One male & 2 females

Which Jamides?

Thanks U.

Post 10.

1. Euthalia monina male.
There are many more variations than what is shown in the reference books.

2. Pseudocoladenia dan.
The male can always be recognised by its horseshoe FW cellspot.

4. Nacaduba kurava male. FW termen straight; submarginal spots large with rounded inner margins ; HW submarginal spot 6 large typically quadrate.

Practically all Jamides can be recognised by the HW white striae forming a sharp spike near the inner margin (in a set position.)
eg. Jamides alecto male & bochus female.

Dr Seow,

Help needed for the below species.

Pyroneura latoia?
butt-id-15.jpg

Arhopala pseudomuta?

Thanks.

Post 13.
They are both correct.

1. The silverstreak on the FW characteristic.

2. The paler forms of Arhopala alitaeus are often confused with pseudomuta.

A. alitaeus : darker, more contrasted & often purple-washed.
HW postdiscal spot 6 is more broadly rounded; submarginal spots are almost separate lunules (half-moons).

A. pseudomuta ;Typically pale with poorly contrasted markings but some are darker causing confusion with A. alitaeus.
HW postdiscal spot 6 is more quadrate (squarish) & smaller ; submarginal spots are 'flatter' forming a running band.
