Correction.

Post 14. no. 5.
Probably Caltoris bromus female.
The antenna do not match that of Polytremis lubricans.
Male P. lubricans in the same posture for comparison.

Female Caltoris bromus often have a spot in HW space 2 & 3 ,sometimes one in space 2.
Caltoris bromus Taiwan male & female.

There appear to be a single hyaline spot in HW space 2. seen only in C. bromus female here.

Baoris lack the ochreous overscaling & the antenna is mostly black.

Hi Dr. Seow,

Would like to add on a couple more skippers for ID.

1) Caltoris sp.? but I do not see pale area on the antennae.

2) Antennae largely black, could this be Baoris sp.?

Three Caltoris in Singaporehave noticeable pale areas on the antenna.

Female.

Male.

3. Caltoris bromus.
Female.

Two species have the antenna largely blackish.

4. Caltoris malaya
male.

5. Caltoris philippina
male.

1. The FW is raised high enough to indicate no upper cellspot & so by deduction no cellspot at all.
The individual is rather worn & faded.
The lack of cellspot inicate Caltoris malaya.


3 Caltoris malaya female.
The 2nd pic shows the upperside with no FW cellspot.
The female is typically mote ochreous ie yellower.


Post 14 no 5 looks very much like C. malaya & is probably so.
The HW spot in space 2 may be just an artifact, & not a real spot marking.




2. Baoris probably Baoris farri.

Baoris have a longer swept FW with a sinuous margin.
The antenna appear largely black in side view.
The abdomen is obscurely banded.

It is simply assumed the darker one is B. oceia & the lighter brown one B. farri.


Supposedly B. oceia male & female.

Supposedly B. farri male.

This female from Vietnam is correct as B. oceia does occur in Vietnam.
