Lycaenidae species collection

[horace2264]

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.
This is one of those individual variation that can cause a lot of confusion. It is a good thing that you bred the specimen otherwise we will not be aware of it
TL Seow

Great! In that case, I can regard the male as of N. subperusia as well.

Many thanks for the ID assistance.

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

Pic 1 Female I. helicon. Note forewing postdiscal band staggered in an arc. Hindwing slightly angular. Probably slightly deformed.
pic 2 Male Nacaduba beroe. Note somewhat broad forewing submarginal band with lower inner margin not indented by the veins; large submarginal spot in space 6 on the hindwing; wing base noticeably darkened.

Pic6. Nacaduba kurava male. Note broad band as in N beroe, but inner margin gently scallopped to gently stepped lower down. Large submarginal spot in space 6 on the hindwing. Wingbase not darkened. Female with larger spots ,deeply scallopped inner margin and hindwing large spot ovate. (see Ellen Tan's N. beroe)

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.

WoW!!

Many Thanks Seow!!!

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 !!

[Peacock Royal]

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.

No problem, Seow.

Khew has both male and female specimens of the Four-Line Blue I bred. Hence we can further confirm the ID with the upperside shots of them at a later date (when Khew has the time to process the shots).

[Psyche]

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.

[Yano]

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?
