Arhopala evansi.

Arhopala cleander group.

Attachment 28529

Subgroup cleander. Very large. 2X that of the alea subgroup.
Wide spacing between the postdiscal spots & the submarginal spots/band on the HW.
eg. A. athada.
https://blogger.googleusercontent.co..._adult_m_3.jpg
.
Subgroup alea
Medium HW postdiscal & submarginal spots coming very close at certain points.

Arhopala evansi.
Underside ground with a slatey pink glaze ,striae whiter giving a sharp contrast.
FW postdiscal band widen slightly below spot 4 (not visible here.)
Upperside blue bright , just less than sublustris.

#3. https://www.inaturalist.org/observations/215741236

Euploea sylvester harrisii.

Only one species here in which the male have a double brands on the FW.
Only two species here in which the male flashes briliant blue on the wing, ie. E. sylvester & mulciber.

https://www.inaturalist.org/observations/31386844


Euploea algea may looks similar but the blue is dark & it largely appears a blue-black on the fW.
The HW submarginal spots are much more elongate.

#4. https://www.reddit.com/media?url=htt...da9e6d49d6b6a8

Euploea mulciber.

The FW apex is bluntly produced & the underside have only small spots.
In particular, there is always a white streak in the HW discal area. (Just visible here in pic 1.)
https://www.butterflycircle.com/chec...2030-12-06.jpg

#5. https://www.inaturalist.org/observations/215661003

Tanaecia cocytus aoyamai.
Probably better as Cynitia cocytus aoyamai.

According to the Yukata website aoyamai is the subspecies in Kedah & Langkawi.
https://yutaka.it-n.jp/lim2/721030030.html

Male FWs strongly falcate.
Blue border largely greyish.
Brown area with large diffuse darker & lighter spots.

#6.https://www.inaturalist.org/observations/215639735
#7.https://www.inaturalist.org/observations/215639734

Uncertain.
Probably one species here.
The general appearance suggest Eurema lacteola, but the inclination of the black border in FW space 2 & 3 even on the upperside seem variable & inconsistent.
Most of the uppersides suggest E. andersonii.



#8. https://www.inaturalist.org/observations/215626571

Borbo cinnara.
HW with the usual spots 2, 3, & 6. Extra spots may be present in spaces 4 & 5. No HW cellspot.
FW subapical spots in an arc. Antennal clubs thick.

#9. https://www.inaturalist.org/observations/214487628
Your Neptis shots all seem off focus making the bands diffuse & broad.

Neptis leucoporos.


Three species are very similar.
Attachment 28530

Neptis leucoporos cresina.
FW spot 3 reaching the submarginal spot. spot in space 1b always small.
Abdomen with a white band in line with the discal band.
HW discal band not reaching the costal margin.
Underside grey.

https://www.butterflycircle.com/chec...erick%20Ho.jpg
https://blogger.googleusercontent.co..._Sunny_01c.jpg


Neptis nata.
FW spot 3 well inside the submarginal band.
Spot in space 1b relatively large.
Abdomen without a white band.
HW discal white band reaching the costa (UnH view.)
https://yutaka.it-n.jp/lim1/720190020.html
https://thaibutterflies.com/Butterflies/neptis-nata/
N. nata is actually the clear sailor.
https://www.ifoundbutterflies.org/si...ac56a1-2_0.jpg


Neptis sedata.Very rare.
Ground black.
FW spot 3 near submarginal spots .
Abdomen without a white band.
HW discal band reach costa..( view UnH)
https://yutaka.it-n.jp/lim1/720130001.html
https://thaibutterflies.com/Butterflies/neptis-sedata/


Two other spp. N. clinia & cliniodes are more brownish & sullied.
https://www.ifoundbutterflies.org/si...13aaf858-1.jpg
Uncertain N. clinioides .HW band eXpands upwards reaching costa.

TL Seow; Cheers.

Again, thanks so much Dr. Seow. Learning so much from your informative identifications even with illustrations.

Cheers from Penang, SL Liew

This is the very rare Neptis sedata. Correction:Probably just N. leucoporos.
The markings are practically similar to Neptis leucoporos but the ground colour is darker, black.
The abdomen lacks the white band seen in N. leucoporos, it being replaced by a greenish shiny patch.

Neptis sedata
https://thaibutterflies.com/Butterflies/neptis-sedata/


Neptis leucoporos for comparison.

TL Seow: Cheers.
PS. There is an observation from Singapore which is N. leucoporos but the abdominal band is white in a side view & green in a top view.
https://www.inaturalist.org/observations/216732688

This need an underside view.
In N. sedata the HW discal band reaches the costa ,but in N. leucoporos it does not.

Noted your additional information of Neptis leucopors vs Neptis sedata. Thanks!
