[SL Liew]

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.


3. https://www.inaturalist.org/observations/234678070
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
Female Quedara.
eg.
https://yutaka.it-n.jp/hes/91875001.html

Hyarotis stubbsi have a white dot on the antenn & a spot 3 near the 'step' on the outer border of white band.
Female with subapical spots.

6.https://www.inaturalist.org/observations/233627478
Halpe wantona or pelethronix.
See fieldshot of male from Kanchanaburi at page bottom.
https://yutaka.it-n.jp/hes/91410001.html

H. sikkima have more uniform HW ground.

7.https://www.inaturalist.org/observations/233627464
Halpe elana.
https://yutaka.it-n.jp/hes/91280001.html


8.https://www.inaturalist.org/observations/62016820

Zenonoida discreta.
FW spots whiter .
HW cilia whitish.

Z. eltola
FW spots & HW fringes yellow.

9. https://www.inaturalist.org/observations/257119824
Anrhene licates.
UnF with a large cellspot.
UnH without a dark spot.
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
UnH spot 4 & 5 suggest it is Polytremis lubricans.
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.
Interneural dark spots thick with rounded outer margins.

Halpe species are terribly difficult.

H. arcuata (& H fishigina)
UnH discal area not paler & interneural spots narrow & mostly separate.

H. sikkima
Similar to H. arcuata. Antenna with white spot & orange tip.

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).
