I think it's a J. pura as it is the only one that has the incomplete bars in the discal area of the hindwing bt the other lines dn't look like the J. pura in C&P4.

Nacaduba berenice icena
The commonest of the 6-line Blue is also the most variable. In particular the forewing postdiscal band can be dislocated at all points, not seen in the other species. The forewing submarginal band is narrow; the upper three spots are somewhat pyramidal and the lower three narrow rectangles. The hindwing submarginal spots tend to be broad or distorted Vs. Females have marginal spots which bulged in the middle, while males have more level spots.
Note, all females except male at seepage and the Catopyrops.

poor pic, probably N.berenice.
Last pic probably just Jamides celeno.

Thanks for helping us to ID the butterflies! Really great to have you on board with us! :cheers: :cheers: :cheers:
Many thanks for confirming that the 4-Line Blue is indeed Nacaduba sanaya. :cheers:Quote:

Your comments on their ID will be very much appreciated. :)
You're welcome. I forgot to add two things which may have been confusing everyone in the past.Quote:

This is great, Seow. Now we can at least confirm and re-confirm some of the species that had stumped us.
Ant, can you consolidate the pics (cut and paste) and then put Seow's descriptions with the pics on this thread? That way, we can read the descriptions and see the pics together.
Horace, you got an interesting pair there. The female at the top is clear- cut N. subperusia. Note the very narrow space between the two adjacent bands. The male at the bottom is another matter. The lower space in space 4 is very wide while the upper space in space 5 is narrower than the postdiscal band to the inside while much wider than the submarginal band. At least in N. sanaya the width of the two spaces are equally wide, while the marginal spot in space 3 looks similar.Quote:

TL Seow
Great! In that case, I can regard the male as of N. subperusia as well. :gbounce:Quote:

A correction
The width of the space at space 5 is equal to the submarginal band not ' much wider@.

Many Thanks Seow!!!:cheers:
AN APOLOGY
Sorry guys ! This is where I need to take humble pie. After checking all the specimens I realised it is not correct for the male of N. subperusia to have the gap so wide. The operative words in the key is that the striae in space 4 & 5 NEARING TOUCHING which is not quite the case here even with the females. More over the postdiscal band is noticeably dislocated near the top end which is not so in N. subperussia.
All those which I have identified as N. subperusia are N. sanaya.
Once more , very sorry guys !!
TL Seow
Seow, thanks for the id of my shots.
Thanks for sharing your knowledge and expertise. Your descriptions of the species are very useful for us to progress to the next level of understanding and learning many of these under-studied lycaenids.
We are very fortunate and honoured to have you here.:cheers:
No problem, Seow. :)Quote:

Thankfully, Horace's breeding success means that the extent of variation of N. sanaya is better known. I thought that a new key is in order for N. sanaya to prevent future confusion, and also for N. subperusia in case someone manage to shoot one.
Nacaduba sanaya elioti
Forewing postdiscal band distinctly dislocated at vein 6.
Hindwing submarginal spots in space 4&5 low-domed, and usually the postdiscal band is a band's width from them, but sometimes fairly close. Submarginal spot in space 6 a llttle larger than the spot in space 5. Marginal spot in space 3 rounded.
Nacaduba subperusia lysa
Forewing postdiscal band not or hardly dislocated.
Hindwing submarginal spots in space 4&5 high-domed, the postdiscal band very close, and their white striae almost touch. Submarginal spot in space 6 large and about 2x that of the spot in space 5. Ocellus ringed with distinct orange.
TL Seow
Ciao for now. Off for hol - 2 wks.
The photos were shot yesterday in Singapore. They are of the same individual.
The hindwing orange markings extend to vein 4 and the white spot inside the submerginal black spot in space 3 is almost disappearing. There is a small additional submarginal orange marking along vein 5.
I guess it can still be the Metallic Caerulian but can it be something else?
Yano
Didn't realised there is a new posting.
The great difficulty is separating J. elpis & alecto.
This is a female so the upperside spots seen are no use for ID.
In J. alecto the pairs of white striae on the lower part of the forewing in space 1b & 2 are equally broad (or roughly so).
In J. elpis the inner pair are noticeably thinner than the outer 2.
Examples of J. alecto & elpis with extended orange had been shot before, but it is more extensive in J. alecto.
TL Seow:cheers:
PS. If the forewings are lowered, a 2nd ID option is:
In J. alecto, the outer of the pair of cellend striae (2nd pair from base in the middle) is as thick as the marginal striae in space 2 & 3 (above the tail).
In J. elpis the outer stria at the cellend is thinner than the marginal striae in space 2 & 3.
Note ID features not absolute, but useful
Dear Seow,
Many thanks for the ID and the comment that "Examples of J. alecto & elpis with extended orange had been shot before".
Today I went to the location again in a hope that I could find some more extended orange butterflies, but coulnd not find any.
