Male Potanthus ganda .
1. The abdominal end is yellow (only 3 species in Singapore have this, namely P. omaha, ganda, & confucius.)
2. The HW band's veins are not dark-dusted.
3. FW band is crossed by light tawny veins & dark veins also run to costa from the cell.
Males P. ganda.

Female P. ganda .Note HW veins not visible.

Male P. omaha have veins blacken above.

Male P. confucius yellow with the band continuous & veins barely darken.

Male Potanthus trachala.

FW spots 4 & 5 not overlapping the subapical spost above or spot 3 below.
HW upper spot of band strongly projected out.
Abdominal end black-banded.

3. This gets difficult as the 4 views are identical.
https://www.inaturalist.org/observations/173422464
Potanthus ganda pair. Correction: Possibly P. omaha with the veins off focus.
Abdominal end yellow.
Male at top; FW veins only lightly brown. Upperside costa with two dark veins.
Upperside vein dividing subapical spot 7 & 8 incomplete. (All veins separating subapical spots 6, 7, & 8 are completely black in P. omaha.}
The male have some overlap of spot 5 & 6 but this is seen insome examples of all P. omaha, ganda, & mongo.
Female with faintly dark veins, spot 5 small.

Compare upperside P. omaha male. Veins dividing the subapical spots are completely black.

The male P. confucius have the costal yellow patch complete, hardly crossed by dark veins.
Ssp. dushta.

Ssp. angustatus.

Example of P. omaha in w3hich FW spot 5 overlaps spot 6.

Also P. mingo

Of the few female P. confucius I have seen all have a large HW spot 6.
Similarly the Taiwanese ssp angustatus female also seem to have a large HW spot 6.
H.K. female.

Finally this shot is too dark to see the details properly.

You can make out the veins on the FW are weak & blur, not defining the spots eg spots 4 & 5 well.
There is good overlap of thev FW spots, HW spot 6 is large.
This is a male & close to 1st male from Nan. Note not all males have large HW spot 6. Note male from Lampang is unlikely to be a male P. confucius.

All male P. omahahere have no HW spot 6.

Dear Dr Seow,

I have brightened that image Zick has brought up! Hope it helps. I personally believe it is P.omaha.

2. While I have found a few Potanthus shots of mine that have a large HW spot 6, the FW spots 4 and 5 aren't broadly overlapping with the adjacent spots as seen here but I'm not too sure.

Will be looking out for more photos once I'm done with class! Thank you so much in advance!

I agreed both should be Potanthus omaha as the HW veins are fairly dark dusted.

The 1st pic is exceptional for the wide overlap of the FW spots & the very large HW spot 6.

Still I would like to introduce a species very similar to P. confucius, a bit larger.
There is a possibility this could find its way to Singapore.


Potanthus pava. FW 15mm.
Abdominal end yellow with basal black line/narrow band.
FW band continuous as in P. confucius Overlap may varies.Male may have the base of space 2 yellow shaded (as in T. colon or besta)
HW with a prominent spot 5 in both sexes usually large espceially on the underside.
Underside bands edged in black streaks, not spots.

Female.

Hostplant Bamboo, Imperata (Lallang).

Distribution : India to Taiwan, Philippine & Sulawesi, in open secondary forest.
In P. Malaysia rare but known from Perak as far back as 1956.


Note the 1st male have the general appearance of P. pava male but the black edgings of the band seem missing.
