Skipper ID request

[Zicky]

Hi Doctor Seow,

I would like to enquire some ID of skippers, looks like im out of touch with their ID, require some practice.

Inat link - https://www.inaturalist.org/observations/265659884
I put this as Polytremis lubricans, (and initially Baoris) but the forewing seem to be missing one of the spots on the usual parts. Would like to ask for your opinion of what do you think it is. How would you split Polytremis from pelopidas similarly? And Caltoris and Baoris if theres any obvious way to tell them apart

For the others:
Caltoris cormasa?

AS to the difference.

Polytremis.
HW always without a cellspot.
Also without spot 7.
HW spot 4 is usually oblongAntennal shaft not fully black, actually checkered.
FW cellspot two ,sometimes conjoined.

Pelopidas.
HW almost always with a cellspot, very rarely it may be absent.
Spots whitish, HW spot 7 often present

Baoris.
Male with sharper FW & an incurved lower margin.
Ground colour uniform on both wings.
FW with reduced spots in the male & upper cellspot often a streak or crescent.
HW may have a vague pale shading at cellend.
In focus HW veins are prominently raised.
Abdomen more noticeably banded.

Paler forms .There is uncertainty whether these constitute B. farri.

C cahira.
Female taken by Federick long ago.
https://4.bp.blogspot.com/-7l1dr3n_g...ris+bromus.jpg

https://farm9.staticflickr.com/8170/...48f3ce8b_z.jpg
The chocolate HW varies in intensity.
This observation looks very much like it should be C. cahira.

3. https://www.inaturalist.org/observations/261319844

They are both Baoris likely B. oceia.

7. https://www.inaturalist.org/observations/249307477
Uncertain.
The colouration suggest it might be a female C. philippina.


8.https://www.inaturalist.org/observations/240503292
Male Polytremis lubricans.
The colour, antennae, & series of fine spots on the HW indicate this species.



9.https://www.inaturalist.org/observations/245937307
Pelopidas probably P. agna female.
There is a cellspot right on the main fold line running through the cell.
There is also a spot 7.
Both are not found in B. cinnara.
The largely light underside suggest P. agna.
(a worn P. mathias would appear quite dark/greyish.)


10. https://www.inaturalist.org/observations/240503301
Malec Telicota colon.
The FW spots are typical.


11. https://www.inaturalist.org/observations/239946407
Female T. besta.
The markings are as for T. linna or besta, but the HW veins across the band are clearly darkened.

TL Seow: Cheers.

Hi Doctor Seow,

I was browsing through Taenaris horsfieldii in C&P5 and decide to take a look online. All online records i found of photographs are found in Borneo, though C&P5 mentions its found in johore primary rainforest. Do you happen to know of any records of specimen collected in Johor? I find this to be interesting as I like this genus a lot, and know Taenaris horsfieldii is the only representative of its genus in Malaysia. Johor has been going through quite some development, so i was curious to know if there might be anywhere specific to take a look in the future as a consideration
