1.https://www.inaturalist.org/observations/337927370

Chersonesia intermedia.

Two species have the 3rd band from base single, not doubled edged black.
The postdiscal band is undulate not straight.
28969
(Attachment drawing correction :Chersonesi intermedia not risa)
In C, rahria the FW apex is darkened cwith a curved fascia (actually composed of two spots)
https://yutaka.it-n.jp/cyr/730070001.html
Below pic 1.
Pic 2 is C. intermedia.
https://wingscales.com/Nymphalidae/Chersonesia-rahria-rahria


C. intermedia.
The FW apex lacks a dark area and have a single subapical spot.
https://yutaka.it-n.jp/cyr/730080001.html
https://wingscales.com/Nymphalidae/Chersonesia-intermedia-intermedia


2. https://www.inaturalist.org/observations/338071854
Chersonesia rahria.
Note FW apex.


3. https://www.inaturalist.org/observations/337931790
Too dark. Probably female Cephrenes acalle.

4. https://www.inaturalist.org/observations/338014285
Male Cephrenes acalle.

5. https://www.inaturalist.org/observations/338071884
Too dark.
Probably female Cephrenes acalle.

The female C. acalle is very variable, essentially like a darkened Telicota.

[Psyche]

6.https://www.inaturalist.org/observations/338014289
Potanthus probably male P. ganda.
Pic 2 shows yellow abdominal end + markings indicate either P. ganda or omaha.
UpH veins appear to be lightly dark.

True P. omaha is rahter dull, ochreous although fieldshots are rather confusing.
No prper underside shot.
P. ganda is more orange.



7.https://www.inaturalist.org/observations/338050266
Male Nacaduba beroe.
Costal spot above the midcell band is missing and the dark striae weak.
The two spot are irrelevant. They are the silvery streak seen in the black spot.



8. https://www.inaturalist.org/observations/338085748
Unknown but very likely J. celeno.

9 .https://www.inaturalist.org/observations/338003569
Unknown female. Very likely J. celeno.


10. https://www.inaturalist.org/observations/338021227
Male J. celeno.
Just enough of the UpF margin to show it is black.
In J pura it is practically a black line/thread.


11. https://www.inaturalist.org/observations/338050256
Unknown but likely to J. celeno from the very rounded FW.

13. https://www.inaturalist.org/observations/338071893

They are best left as P. athamas for the moment.
Tousaint's study have uncertainty regarding the sampling in P. Malaysia.
Only P. paulettae can be confirmed to occur in P. malaysia.

P. hebe always have the FW band wider than the HW band.
Two other features.
FW postdiscal spots are reduced and often deformed.
HW postdiscal spot in space 3 with a bar/crescent highlight.

14.https://www.inaturalist.org/observations/338021239
Uncertain.
Likely Tanaecia iapis/cocytina.
THe two species can be very difficult in fieldshots.

T. flora have the HW blue band strongly tapers upwards.
The UnH marginal zone is paler.
https://www.gbif.org/occurrence/2242800920
https://www.gbif.org/occurrence/2242799810
https://www.gbif.org/occurrence/2847205019
https://www.gbif.org/occurrence/2847205016


T. iapis/cocytina have the HW blue band starting to widen up at the costa.
The UnH marginal zone is not paler.
https://www.gbif.org/occurrence/1898830171
https://www.gbif.org/occurrence/1990600014
https://www.gbif.org/occurrence/2847206842
https://www.gbif.org/occurrence/2847204949
https://www.gbif.org/occurrence/5761594024

Although the individual shows a aligned blue border and tapere HW band, the HW blue taper is not abrupt as in typical T. flora.
More importantly the UnH marginal zone is not paler.

The genitalia of the t5wo species are very similar.
https://yutaka.it-n.jp/lim2/721070010.html
Note below the males from N. Si Thammarat and Narathiwat are likely misIDed T. iapis/cocytina.

Pantoporia paraka.
Two features.
1. Both FWc submarginal bands are orange.
2. The costal zone ahve irregular spots.
https://wingscales.com/Nymphalidae/Pantoporia-paraka-paraka



16. https://www.inaturalist.org/observations/338085747
Neptis clinia.
Note the basal white spot in space 3 on the HW.



17. https://www.inaturalist.org/observations/338171416
Pelopidas mathias.
FW spot 2 & 3 in the correct perspective are quadrate in shape.
See image 3 & 4.
https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhZ0r_3l__7RDlGef00RM-yXV0rJoptLLDDU6OWc5meFIc_8M_EbdrB3gdBA9cJ9MFo-0KsGvlW8rH9WCRcNfR0wJ-tVJWTr-lulCyJ6lItie0WT5w8CQm7FN6pNj5nD10nkmTGA70VeqEE/s1600/SBS_adult_male_upperside_01.jpg

In male Pelopidas agna these spots are typically narrow.

18.https://www.inaturalist.org/observations/338090049
Halpe ormenes.
H. ormenes consistently have the HW band broad at the lower end.
The outer margin is frizzy with shallow incisions and the band is usually white but may be yellowish.
