ID requests - Peninsular Malaysa from RY - Feb 3, 2025

Hi Dr. Seow,
RY (aka dilophobia in iNat) a teenage butterfly enthusiast based in KL has requested my help to forward these observations to you for identification. I understand these single view photos may be difficult or not possible to confirm species id. Thank you for any id feedback wherever possible. Appreciate it.

1. https://www.inaturalist.org/observations/234678102
Probably P. athamas.

The single sample of P. paulletae was taken from Cameron highlands .
It should have two subapical spots ,& longer tail.
https://upload.wikimedia.org/wikiped..._and_Range.jpg

Eliot opined that the lowland population of athamas consist of two species.,athamas from the mainland & uraeus of Sundaland.

It is unfortunate the two samples of athamas for molecular analysis were taken from southern China & extrapolated to include the whole of SE Asia.

P. athamas have the longer taila and one, rarely two subapical spot.
The taxon uraeus as ssp of attalus have very short tail & one subapical spot.
https://species.wikimedia.org/wiki/P...asMUpUnAC1.jpg


2. https://www.inaturalist.org/observations/234678062
This is very worn with the tail torn.
The strongly notched (concave) HW spot 6 meant either eulmophus or horsfieldi.

Allotinus sarrastes.
HW spot 6 in line with the rest of spot 2 - 5.
FW postdiscal series of spot with a mid break.
Submarginal spots have white edges, pcture quality poor.


4. https://www.inaturalist.org/observations/234678090
The ochreius brown colour & reduced spot suggest C. sirius.
C. malaya is a deeper rusty brown in the male.

5.https://www.inaturalist.org/observations/257119821

https://blogger.googleusercontent.co...C_0438-001.JPG



10.https://www.inaturalist.org/observations/242284621
The long FW & plain colour suggest Pithauria straminaepennis.
https://www.ifoundbutterflies.org/si...99959a-1_1.jpg


11.https://www.inaturalist.org/observations/233627474

https://www.ifoundbutterflies.org/si...fc7391e1-1.jpg

12.https://www.inaturalist.org/observations/260157412

Probably Halpe pelethronix.
UnH with heighten pale doscal zone & darker veins.

Halpe species are terribly difficult.

H. arcuata (& H fishigina)

https://thaibutterflies.com/Butterfl...lpe-arcuata-2/
https://wingscales.com/Hesperiidae/Halpe-fushigina


H. sikkima

https://yutaka.it-n.jp/npict15c/91300001_n002.jpg
https://yutaka.it-n.jp/npict15c/91300001_n001.jpg


Halpe pelethronix.
UnH with a heightened paler discal zone.
interneural spots mostly broad with rounded outer margins.(educated guess).
https://thaibutterflies.com/Butterfl...e-pheletronix/

Halpe wantona.
UnH similar.
Interneural spots narrower with pointed outer margins.(educated guess).
https://thaibutterflies.com/Butterflies/halpe-wantona/

13. https://www.inaturalist.org/observations/257119817

Probable Caltoris cormasa.
FW with subapical spots so not ossible to be Hyaritis.
General three subapical spots & reddish tone suggest C. cormasa.



14. https://www.inaturalist.org/observations/260157415
Probably Zographetus rama female.

Markings similar to Z. ogygia. Antenna with droad white patch.
https://blogger.googleusercontent.co...-HoraceTan.jpg

Salanoemia fuscicornis have strong markings.
https://encrypted-tbn0.gstatic.com/i...sMHauXqzXIWw&s

Isma protoclea has smaller white on antenna & different UnH spot arrangement.
https://yutaka.it-n.jp/npict15c/91890010_n001.jpg
https://res.cloudinary.com/ppc1/imag...wzeojxfmx6.jpg

Harotis iadera have a tiny white dot on antenna * unH spots very vague.
https://thaibutterflies.com/Butterfl...arotis-iadera/

15.https://www.inaturalist.org/observations/233627461
Borbo cinnara.
UpF spot 2 with concave margin ;spot in space 1b always present.
FW subapical spots in an arc. Thicker antennal club.
UnH typically with three spts 2, 3, & 6.
https://yutaka.it-n.jp/hes/93060001.html
https://wingscales.com/Hesperiidae/Borbo-cinnara

Caltoris does not have HW spot 6.




16.https://www.inaturalist.org/observations/233627467
Yasoda pitane.

Yasoda pitane laruta.
UnH with white scalings forming a diffuse weak submarginal band. If visible diagnostic.
https://www.gbif.org/tools/zoom/simp...7150b2fc004a08
https://www.gbif.org/occurrence/2847199517

https://www.gbif.org/tools/zoom/simp...87f417c72e28ec
https://www.gbif.org/occurrence/2847201736


Yasoda pita dohertyi.
UnH lacks any trace of white submarginal scalings.
https://wingscales.com/Lycaenidae/Yasoda-pita-dohertyi

17.https://www.inaturalist.org/observations/176567275

Pyroneura niasana.
A line thru FW subapical spots 6 & 7 is directed to the termen (outer margin(.
Unh vein 8 scaled orange on both sides.
UnH dark ground about twice as wide as orange veins.
Female.
https://wingscales.com/Hesperiidae/P...iasana-burmana

P. perakana is very similar with FW spots 6 & 7 directed to termen.
But UnH orange veins are nearly as wide as the dark ground spacrs.
Male.
https://thaibutterflies.com/Butterfl...eura-perakana/


In P. natuna & helena the alignment of FW spots 6 & 7 is parallel to the termen & runs down to the lower margin.

18. https://www.inaturalist.org/observations/249756945

Halpe hauxwelli.
FW with two cellspot which may be conjoined.
UnH pale buff with a series of postdiscal interneural spots & marginal spots.
https://wingscales.com/Hesperiidae/Halpe-hauxwelli



19.https://www.inaturalist.org/observations/234837398

The markings are as for Halpe wantona/pelethronix.
Since the UnH postdiscal interneural spots are sharp-pointed, it is probably correct as H. wantona.



20. https://www.inaturalist.org/observations/199180321

Matapa aria.
FW & HW cilia of the same pale buff tone.
Outer margins strongly edged in black.
