It has been quite a long time since my last post here - because I have not got something "interesting" to post.
Here are four species I have not encountered for a long time.

9. Likely to be the Nacaduba pavana singapura


10. Nacaduba berenice icena ?


11. Likely to be the Jamides elpis pseudelpis


12. Logania marmorata damis


13. Abisara geza niya

8 a, b, & c. Potanthus mingo.
P. mingo is probably not a rare species but easily confused with trachala or ganda.

Potanthus mingo ;more yellow ;
FW spot 4 & 5 with overlap to spot 3 (variably to spot 6 above), spot 2 & 3 wider (ie more rectangular) ,their outer margins not strongly concave;
HW upper spot (4 + 5) of band not strongly projected out; Abdominal end black banded.

Potanthus trachala. ; darker orange.
FW spot 4 & 5 without overlap to the spots above & below. spot 2 & 3 quadrate with strongly concave outer margins; UnF spots spiky.
HW upper spot (4 +5) strongly projected out; abdominal end black -banded.

Potanthus ;deeper orange;
FW spot 4 & 5 with partial overlap with spot 3, little with spot 6 ;spots with straight margins.
HW spot 4 + 5 slightly projected.Veins not or barely darkened. Abdominal end yellow.

1o Nacaduba berenice.
This male is unusual in having broader submarginal spots.
FW margin rounded; submarginal spots with irregular pointy margins.Dark striae always strong in the male.FW postdiscal band often dislocated or kinked in the middle.

N. kurava; male with rather straight FW margins; submarginal spots with rounded margin; postdiscal band intact typically straight.HW spot 6 blocky.
Dark striae weak in the male.

Dr Seow, do you think #9 is N. pendleburyi? I chanced upon this photo by Richard recently which i'm very certain is N. pendleburyi and it looks very similar to Federick's.

What do you think?

Federick no. 9 is Nacaduba hermus for two reasons.
1. HW postdiscal & submarginal spots in space 4 & 5 very close ,almost touching.
2. HW tornal black spot with metallic scales.


N. pendleburyi & sanaya shares the following features.
HW postdiscal band & submarginal spots in separated by at least 1/2 the width of the postdiscal band.

The males of the two are seperated thus.
N. pendleburyi FW border increases at apex.
N. sanaya FW border a thread throughout.

No separation for the female.

N. sanaya almost always have a dislocation of the FW postdiscal at vein 6 (sometimes 5).

C&P4 shows a N. pendleburyi with very narrow submarginals & HW spot 6 a chevron (or arrowhead); FW band not dislocated.

I have been unable to locate previous N. pendleburyi image.
N. pendleburyi do not have HW tornal black spot with metallic scales.

N. sanaya is very variable in the separation of the HW postdiscal & submarginals.

India have neither subperusia or pendleburyi.
The metallic scalings may be meagre in some forms esp. dsf. of N hermus.

Richard's shot is hard to say, for it could also be N. sanaya or hermus though the metallic scales are just a few.
The submarginals are narrow as in pendleburyi but the HW submarginal spot 6 is not a chevron (V-shape).

I would need to locate some correct shots of N. pendleburyi for comparison,

Thanks Dr Seow. I was misled by the wing shape. The forewings are streched forward so they appear more elongated.

Richard's shot is hard to say, for it could also be N. sanaya or hermus though the metallic scales are just a few.
The submarginals are narrow as in pendleburyi but the HW submarginal spot 6 is not a chevron (V-shape).

I didn't think this was sanaya because the post-discal on the forewing is curved and the distance between the subbasal and discal striae on the hindwing is too wide for sanaya. The striae are also thinner than in sanaya
