ID Needed for Potanthus sp

[Lohhc1]

Hi Dr Seow, need your help to ID this skipper. Is it potanthus omaha omaha?

It looks good to be a P. ganda male.

In P. ganda the veins are not or only lightly dark dusted ; likewise on the upperside HW; also more orange.
Because P. omaha is variable some confusion is expected.
Ideally an upperside HW showing the undarken veins is helpful.

Typical P. omaha males & pair.
Note the veins are evenly dark including those on the FW;abdominal tip always without a dark band.

P. ganda male, Federick Ulu Sumbawang Aug. 2013 .Note veins not darkdusted on both wings; abdominal tip may be dark banded.
Correction: This likely a P. omaha variant.

The next two are correct as P. ganda.

The other species also have the veins not darken especially when fresh.

P.serina male ;large ;sharp FW; FW spot 5 smaller than spot 4. HW band with small upper inner extension; clean look.Abdominal tip always with black band.

The next three species have heavy dark spots on the underside.

P.trachala male. FW spots 4 & 5 with no overlap but linked by spikes to the other ;HW spot 4/5 (upper part of band) project from the lower two spots' outer margins more than in other species.

P. confucius male, Federick, Tampines Eco Park Dec. 2014.
Similar to P. trachala but wide overlap of FW spots 4 & 5 above & below; HW spot 4/5 less projecting.

P. mingo male , Brian ;HW band notched by dark spots creating a zigzag appearance.

P. ganda is not rare but very easily confused with P. omaha.

TL Seow:Cheers.

Thank you Dr Seow for the detailed explanation.

[Psyche]

After much searching & comparing this male is likely just a P. omaha variant.

There are too much dark dustings of the veins compared to all typical examples of P. ganda.

TL Seow : Cheers.
