Sir, could you check this Nacaduba, please? Thought this was N. kurava euplea, the only 6 line one we have but the upperside wasnt transparent from any angle. Would this be N. beroe gythion?

This is rather difficult.
The upperside with the pale dusting suggest N. berenice.
The underside suggest N. kurava.
This need further checking.
Possibly hybrid between the two.
ID is based on the upperside in the male so this is most likely a form of N. berenice.
Nacaduba beroe male.
Dark striae within bands mostly obsolete.
Always without a spot above the midcell band, at the costa.
FW postdiscal band usually broken in the middle.
Upperside deeper violet blue.

Thank you, sir. I was thinking N. beroe gythion. N. berenice may not be found in east Nepal,and there seem to be pics of N. beroe on IFB with spot above midcell band. Matches with some example of N. berenice akaba which is N. beroe gythion now.
The absence of the costal spot above the mid-cell band is an almost certainty in the ID of N. beroe.
There are a number of errors in IFB.
N. berenice is a common species ranging from India to Australia.
Here are examples of the male N. beroe.
N. beroe gythion.

PS[I] . Nacaduba berenice akaba Type location Borneo. There is no change in the status of this. The Bornean ssp of N. beroe is neon the same as in Sumatra, Malaya & Singapore.
Correction.
The upperside is too dark to be N. berenice.
The only explanation is there are two butterflies.
The upperside is that of N. beroe.
The underside shot is that of N. kurava.
TL Seow: Cheers.
No, sir. It's very much a single individual. No doubt on that. Perhaps not all kurava individuals are transparent. Or perhaps it's a hybrid.

I left this thinking it's Erionota torus, but now they appear E. thrax to me. I feel so bad that I didn't take good shots.
Attachment 27331
Attachment 27332
Agreed. It is a male Erionota thrax.
The two can be quite confusing, in S.E. Asia where the difference is less marked.
It is advisable to ID the sex/gender first as this helps in the ID.
Male have the antennal club about 3/4 white.
Female havs the antennal club about 1/2 white.
From the 2nd pic it is a male.
Erionota thrax.

Yes the female Jamides alecto. The UnF white striae are all broad.

Thank you, sir. I need a serious confirmation on this one. Scobura isota isnt reported from Nepal before, and I found a bunch of these in east, near Sikkim in dry season of March. While I saw more than 10 individuals, I managed to photograph several and all were typical S. isota as per Evans '49. Question is, if this is enough or do I need genitalia, which isnt possible for me now.

S. isota & cephala have been much confused.
Scobura cephala.
FW spot 4 always present.
UnH with a large rectangular spot in space 1b, in continuation of the spot in space 2 (In Evans' time space 1b is called space 1c .)
Dsf with lighter brown shadings beyond the spots. In wsf always deeply shaded brown.

Scobura isota.

Dsf unH ground entirely yellow.
WsF UnH with brown shading as in S. cephala.

1. Probably Potanthus nesta.
Potanthus is particularly difficult.
Three species with the abdominal end yellow can be eliminated. ie P. pava, confucius, & ganda.
Three species in which the HW band's upermost spot (4 + 5) is strongly projected out & FW spots 4 & 5 are detached or nearly so are out ie P. pallida, P pseudomaesa, & trachala.
P. rectifasciatus have a very large spot 6 connecting the band to spot 7.
https://live.staticflickr.com/4585/3...39db4bb7_z.jpg
P. dara is pale yellowish with FW spots 4 & 5 detached & a prominent HW spot 6 above. ( Description corrected.)
Male & Female. Correction : These two may be forms of P. pallida with a prominent HW spot 6.
https://www.ifoundbutterflies.org/me...9fae298e-1.jpg

Dear sir,
Could you please check this Celaenorrhinus sp. for me? It looks very much like C. leucocera but has space 1b spot. C. pyrrha is another candidate but this individual lacks pale spots beyond sp 1b spots.

Post 179.
It has to be C. leucocera with a minor aberration.
BY following Evans' keys in two ways.
1. Assuming the sub=basal spot in space 1b is valid.
Key 1a, 1b, 1c, 3a(id), 5a(3b) 6a(5), 9a( 6b), 11 (9b) a dead end C. pero.
https://www.ifoundbutterflies.org/sp...norrhinus-pero
C. pyrrha is out Key 6b to 9. as the antenna is chequered & only the club white.
https://www.ifoundbutterflies.org/me...c174a712cc.jpg
2. Assuming the sub-basal spot is a minor aberration.
Key 1a to 12a(1c) to 15a (12c).
This include 3 species.. C patula, leucocera & putra.
It matches C. leucocera very well.
