Hesperiidae ID Request - Singapore

[loomins_zoomins]

Dear Dr Seow,

Requesting ID for these 2 Skippers.

1. Caltoris cormasa male? I do not see the pale area on the antennae but I'm quite sure of this ID.

2. Caltoris or Baoris sp. I originally thought this was a Baoris sp. but upon closer inspection I do see the pale area on the antennae so I'm not too sure now.

Thank you so much in advance!

Both are Baoris presumably B. oceia males.

The pale area on the antenna is very small mainly on the underside , & is not visible in most individuals.
The male seem always to have reduced spotting in Singapore.

It is extremely rare for a Caltoris like C. cormasa to have reduced spotting.

Baoris male & female.
Male with pale area on antenna, female with a pale patch on the HW cellend (diagnostic).

TL Seow: CHeers.
PS. Baoris & Caltoris are very difficult & some misIDs are inevitable.

Caltoris cormasa should show a contrast of the paler FW against the deeper HW; often 3 subapicals , noticeable pale area on the antenna.
Worn examples.

Caltoris malaya have uniform rusty brown FW & HW; no cellspot; pale area on antenna weak.Female is yellower.
Males.

Baoris have a uniform greyer brown ,ground, male with more swept FW ;often a pale area on HW cellend ; much reduced spotting in the male.
Example with a pale area on HW cellend.

Ohhh I see, thank you Dr Seow!

Dear Dr Seow,

Requesting ID and clarification regarding Potanthus omaha vs Potanthus mingo. If I'm not wrong, P.omaha's abdominal end is usually yellow with a basal black line sometimes for males and dark shading dorsally sometimes for females while in P.mingo, the abdominal end is distinctly dark shaded. Other than that, both species have similar features such as FW spots 4 and 5 having varying levels of overlap with other spots and a generally small size to me. I also understand that in P.omaha there can be individuals with very dark shading which makes it more confusing for me because I'm not sure if the shading will apply to the abdominal end.

1. Potanthus omaha? Abdominal end shaded basally and maybe dorsally?

2. Potanthus omaha due to abdominal end features and darkened veins.

3. I'm not too sure with this one due to the shaded abdominal end. Could it be P.mingo?

4. Potanthus mingo? This one stood out the most to me due to the shading and also that it's the smallest Potanthus I've ever shot.

5. Not related to the question but just wanted to confirm if this is P.omaha, not used to seeing pristine ones!

Post 22.
The difficulty is identifying the female which all have varying degree of dark shading on the abdominal end.
Note P. omaha is the only species which is stated to have dark-dusted veins especially on both sides of the HW.

1. P. omaha male .Abdominal end is yellow.

2. P. omaha male. similar to 1.

3 Probably P. mingo female.
Note abdominal end is broadly shaded black.
FW veins not so distinct; vein dividing spot 4 & 5 hardly dark-dusted.

4. P. omaha female.
Abdominal end more evenly dark-shaded but not as black as 3.

5. P. omaha male. Lightly marked but all veins equal.


P. omaha;
Abdominal end yellow in male, dark-shaded in female.
Veins distinctly dark on HW both sides.
Upperside FW veins strongly black.
Male

Female.

P.ganda
Abdominal end yellow ; Veins not dark-dusted FW & HW both sides .
The typical forms are obvious but there seem many intermediates, ie crosses with P. omaha.
Upperside HW band veins not visible.
Female abdominal end only lightly dark.
Males.

Females. Note abdominal end less dark than others.

P. mingo

Thank you Dr Seow! Hope to find more Potanthus soon!

Dear Dr Seow,

Requesting some ID clarifications for some of JX and I's past and current shots!

1. Potanthus omaha typical male because the abdominal-end's black band isn't that extensive compared to typical P.mingo? Veins also dark-dusted.

2. Potanthus omaha female? Not too sure about this one, would P.omaha have way darker HW upper-side veins than this?

3. Potanthus sp. is this a possible P.mingo? Old shot.

4. Potanthus ganda? The veins look very faint in comparison to the rest of the wings' dark shading so I'm not too sure.

5. Pelopidas agna? Uniform brown.
