ID help please

Just one lascar for now... judging by the rather thick grey lines, I'm guessing this should be P. hordonia. Is it a male or a female?

Correction: Pantoporia sandaka male




Thanks!

Male P. sandaka.

This is one of those which can be rather confusing.
The grey band is much constricted, beaded & mostly disappear above & below.
The foot of the postdiscal band which runs along the lower margin (dorsum) is large & long.
There is a hint of the white speculum on the HW by the white line below the FW.

In P. hordonia the the grey band is broad & continuous &, the foot of the postdiscal band in the male smaller & shorter.
Typical wsf ,P. hordonia hordonia.

Here's a Nacaduba from today... it is quite faded. Is it possible to ID this one?

ID as Nacaduba subperusia lysa

[atronox]

WOW Jon it looks like N. subperusia lysa, which would be a rediscovery. Notice the post-discal series on the hindwing is very straight and practically touching the submarginal series; the gap between is smaller than all the others in the pavana group. The submarginal striae, in stark contrast, are much more rounded than the striae immediately basad to them.

Where was this taken?

[Banded Yeoman]

This was taken in usr! The upperside was a dull purple if I remember correctly..

Concur it is N. subperusia lysa.

N. sanaya can sometimes cause confusion but the FW postdiscal band is always distinctly dislocated at vein 6.

The other similar one which normally is commoner is N. hermus swatipa.

N. hermus swatipa.
FW postdiscal band not or barely dislocated at vein 6.
Dark striae often weakly present.
HW tornal black spot almost always with some metallic blue scales.

USR seems to be home to a lot of surprises!

Thanks Aaron and Dr Seow for the ID input! It is very likely to me that all our original Nacaduba species are still extant, just that they may have been either ignored or mis-identified in the past. It doesn't help that most of our encounters with them are fleeting, flying-by sightings. I often see them fluttering high above the ground in the treetops.

Here are a few more Lycaenids...

In my view, the 6-line Nacaduba species can be more confusing to separate than the 4-line ones. I've attempted to identify them based on what I've read from previous posts. Dr Seow, Aaron, what do you think?


1) Nacaduba berenice male


2) N. beroe male


3) N. beroe male


4) Nacaduba beroe female


Arhopala. epimuta male
