3. I presume this is taken in Singapore.
This is a difficult one It appears to be a new species.
A male with the abdominal end strongly black-banded. FW spot 5 smaller than spot 4.

It is not P. mingo which have FW spots 4 & 5 of about equal size.

It is not P. juno which have FW spot 8 (topmost) missing or vestigial.

It is not P. trachala which have FW spots 4 & 5 (of equal size) without overlapping the spots above & below; they are connected by the spikes.

It is not P. serina which is lightly dark-shaded, & more orangey.

It looks very similar to this P. palnia which underside generally look greenish grey.
Range: India to SE Asia down to Sumatra, but not recorded from peninsular Malaysia.

Nice catch on the A. reta. Where was that found? It's very rare in Singapore

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.)

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.

A female P. juno showing the fully absent FW spot 8 on the underside.

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
