There is only one skipper marked like this, ochreous brown with yellow veins.
The eyes may be red brown ,the redness dependent on the lighting.
The antenna have a black club with a whitish dot at the tip, & a pale area below it.
The subapical spots have the lower one much larger.
FW cilia blackish, HW cilia yellowish.
There are a few features which do not match that of Xanthoneura.
The two subapical spots are spot 6 & 7. (if three then + spot 8)
There is a spot below spot 6 which is spot 4 .ie no spot in space 5.
This is typical in Caltoris. https://yutaka.it-n.jp/hes/93360001.html
Looking back at my past photo, I realise one of the skipper I didn't manage to ID, leaning towards Halpe or Pinthauria. Would like to hear your thoughts
Baoris spp.
Sharper, more swept FW, antenna pale area weak or obsolete; Abdomen obscurely banded.
May have a pale mark near HW cellend.
More often veins prominent or raised.
Two species recorded in Singapore. Current status uncertain.
In the past dark examples were considered B. oceia & lighter brown ones B. farri
This may not be correct. Also many intermediate in colour.
B. farri; more often fully spotted.
UnH silky brown?
UnH should not be much darker than the UnF.
In India where B. oceia is absent these are fully spotted B. farri males.
No fully spotted males are seen in Singapore yet.
Also many females have two subapical spots rather than three.
All males have the upper cellspot lunulate ie a small crescent, not rounded as in males from india.
There is a strong suggestion only B. oceia exist in Singapore.
However, both species can have varying number of spots.
Male Telicota linna.
UnH veins across band not dark-dusted in both sexes.
Telicota bambusae is very similar & easily confused with.
There is a single record from Singapore a century ago but this is now rated unlikely & a mis-ID.
Common in India 7 much of continental SE Asia.
Hostplants include Bamboos & sugar-cane & so could easily spread here. TELIBAM.png
Telicota bambusae bambusae.
Smaller species FW 15mm.
Band often rather broad.
Orange patch base of space 1b bright as the band.
UnF subapical spots 6, 7, & 8 mostly clear.
Some examples may have a weak black smudge at the lower end of spot 8 as in T. linna.
Female upf with two long cellend bars.
Telicota linna .Larger. FW 18-19mm.
The band appear correspondingly narrower.
Base of space 1b orange patch dull, darker.
UpF with the lower end of subapical spot 8 & sometimes also spot 6 marked with black.
Identification based on underside alone is difficult as the difference is not absolute.
This below with broad bands look correct as T. bambusae but it does have a tiny black spot at the lower end of spot 8. https://www.flickr.com/photos/maanay...n/photostream/
Although P. mathias & agna appear to be common in Singapore there is a lot of mixedup with these two species.
Pelopidas mathias.
Male UpF spot 2 & 3 quadrate or at least broad
A line thru the two cellspots cut the brand.
Ground colour grey-tinged ,often giving a dirty uneven shading, darkish around the spots, paler along the margins.. FW cilia darkish compared to the paler HW cilia. Added important clue. https://yutaka.it-n.jp/hes/93120001.html
Pelopidas agna.
Male UpF spots 2 & 3 narrow especially spot 2.
A line thru the 2 cellspots usually bypass the brand.
UnH uniform brown clear, with a greenish tinge (usually not seen in fieldshot). FW cilia as pale as HW cilia but edged blackish. Added important clue.
Many observations, but mostly poor quality singleshot views which make ID difficult.
Many IDs of P. agna but most are doubtful.
This shot is undoubted but the UnH view is poor. Note uniform brown UnH. https://www.inaturalist.org/observations/251275302
