ID needed (1 Nov 2021)

[Psyche]

Two recorded species in Singapore have never been identified .

This lis largely due to their great similarity with N. sanaya.
They are likely to have been misIDed all this while.

Nacaduba subperusia lysa.
HW submarginal & postdiscal spots in space 4 & 5 close together.
HW white striae fairly thick in the male.
Orange ring narrow , less bright.

Singapore probable examples.

Female.Note the orange ring is very dull. Correction: Female N. hermus . This has metallic blue scales on the black spot.

Nacaduba pendleburyi.
HW submarginal & postdiscal spots in space 4 & 5 well seperated.
HW orange ring narrow & dull.
Male upperside FW with very narrow black border widening at apex.

Singapore probable examples.
Male.Note separation of the spots mentioned & dull orange ring.
https://www.inaturalist.org/observations/78555522
This male shows the FW upperside apex black. In the male sanaya this would be blue since there is no widening of the black border.
This male is practically confirmed as male N. pendleburyi.

Female.

Typical examples of N. sanaya 2 males & 2 females, for comparison. HW inner white striae thinner, orange ring bright & well-defined.
