Doubtful IDs from Nepal

[Psyche]

Post 28.

1. Polytremis discreta (also placed in a new genus Zenonoida.)
HW tornal cilia white.


2. Celaenorrhinus putra.

I have only just beginning to understand the complexities of C. leucocera & putra which was so confusing in the past.

C. leucocera; Range India to SE Asia mainland.
FW dorsum (lower margin) > (greater than ) termen (outer margin).
FW termen convex ,apex more rounded.
Discal band generally extend beyond the radius (upper arm of the FW cell).
HW cilia broadly whitish, chequered.

Form with the FW discal band barely extending beyond the radius.

C. putra ;Range Sundaland ,SE Asia to NE India, Assam, Sikkim , Nepal.
FW produced, FW dorsum = termen.
FW termen straighter & in the male noticeably sharper.
FW discal band rarely extend beyond the radius.
HW cila narrowly whitish, less prominent.

The early entomologist amassed drawersful of specimens, yet no record of C. putra was given to South India.
Nor does the checklist for Bangladesh include this species.
Yet many shots from S. India are atributed to C. putra based on the appearance of the discal band.

Separating the species in set specimens was not so difficult as seen in the links below.

All sightings of C. putra in S. India are likely erroneous.
Genitalia shown are doubtful. They depict the left clasp of two different specimens, showing only the outside of the clasps.Correction: Images correctly shows the right clasp & inside.
Genitalia need to show the right clasp with the detail of the inside ,which may have additional features.
Evans made no mention of genitalia difference between the two species.
