[sabafish]

Hi Dr Seow,

Appreciate if you could help me look through the following photos and shed light on some of the species.

Thank you!

1) Initially thought it was Paralaxita damajanti but after seeing abit of the upperside of HW, I am not sure if it is Paralaxita orphna female instead?

2785827859

2) Pyroneura helena?

27860

3) Ypthima fasciata?

27861

4)Koruthaialos rubecula?

27863

5) Koruthaialos rubecula?

27865

6)Idmon obliquans?

27864

7)Nacaduba sp.; unfortunately no upperside shot but just a little peak at the colour on the FW.

2786627867

8) Allotinus sp.; unfortunately no upperside shot too.

27868

9) Allotinus sp.

2. Pyroneura natuna.

Pyroneura natuna & helena are very similar & some authors do not separate the two.

P. helena FW space 5 with a hyaline spot at the end of the opalescent streak.
HW veins yellow.
This would be somethimg like in P. latoia.
https://thaibutterflies.com/Butterflies/pyroneura-latoia/

P. natuna' FW without a hyaline spot in space 5.
HW veins orange-yellow.

http://nlliew66butterflies.blogspot.com/2015/02/pyroneura-natuna-fruhstorfer.html

Additional notes.
P. helena range Sumatra, Malaya & Borneo.
P. natuna Borneo (including Natuna) Malaya & S. Thailand.

Under Eliot these would be Pyroneura natuna, not P. helena.
Note records from Thailand state either as P. helena natuna or just P. natuna.
