Hi Dr Seow,

Seeking your help to ID the following species.


1. Could this be Pantoporia hordonia?

FW inner grey line seems to be wider than the orange line although its quite faded?

Also, could I trouble you to explain where the speculum is? I have trouble visualizing it on the butterfly.

2. Posting on behalf of a friend. Is this Baoris sp.?

3. A very worn out individual. Seems to have cell spot so could it be Caltoris cormasa? The pale antenna region does not seem to be large though.

1 Female Pantoporia hordonia.

The two species are often much confused throughout their range.
In Singapore the two species are more similar possibly because of some crossing.


Pantoporia hordonia.
Grey submarginal band wider than the orange band, which may be broken or much rduced,
The male have a small grey speculum on the HW base which is fully hidden at rest.
Typical male P. Malaysia.

Note small HW grey speculum in set specimen.

Males Singapore.

Pantoporia sandaka.
FW submarginal orange band wider than grey band ,typically intact , unbroken.
Grey band often constrcted into beads.
Male FW postdiscal band's foot extension along the lower margin always large.
HW with a larger white speculum around the base which often shows as a white highlight below the FW.
SSp davidsoni showing the white speculum.

Typical male P. Malaysia.

The female can be rather confusingly similar to the female P. hordonia.
Females Singapore.

Probable female P. sandaka. ( Google zoom 300X ,& the grey band can be seen to be much narrower than the black spacing.

2 Baoris ,probably B. farri female.

Antannae blackish, FW two oblong cellspots.
Caltoris always have rounded cellspot particularly the upper one.
FW underside pale area as in female Baoris.
See female from Chiang Mai.

3. Probably female Caltoris cormasa.
Very worn specimen, usual red tone hardly noticeable, except upperside FW.
Spot markings as in C. cormasa.
Pale area on antenna may darken with age.
3rd picture is suggestive of C. cormasa.

Other two possibilities C. bromus & cahira seem unlikely.

Thanks Dr Seow!

I'm also seeking your opinion on the following Rapala.

Could this be Rapala damona? Searching through the web and other online platforms does seem to show that R. damona has a larger filling at space 1b compared to R. suffusa.

Thank you!

[Psyche]

Yes. This is a Rapala damona male.

The large speckled patch is particularly significant in Sundaland..Sumatra, Malaya, Java & Borneo.
These examples are from the Andaman islands north of Sumatra.
https://www.ifoundbutterflies.org/rapala-damona.
You can also check Otsuka 's specimens in the Borneo Lycaenids.
You can download it here.
http://www17.plala.or.jp/jamides/Bor.../borneo-e.html


The examples from continental Asia have a smaller speckled patch about 60 - 70 % coverage.
http://yutaka.it-n.jp/lyc4i/84000001.html


Do not simply accept images from website.
Try to cross check if you can.
Many errors occur.

Rapala damona is one.
This example from northern Thailand is Rapala dieneces, not R. damona.
The HW 's upper third is largely black.

TL Seow: Cheers

PS. Helpful features.
If the HW speckled patch is small & the postdiscal line/band is angled sharply it is always R. suffusa.
Female.
https://www.inaturalist.org/observations/124393458

The postdiscal band is rounded above the speckled patch is rounded in R. damona & dieneces.
R. damona female.

R. dieneces female.
