Nacaduba kurava?

[horace2264]

Dr Seow, is this 6-Line Blue a Nacaduba kurava?

24085

[Psyche]

A difficult one . It is halfway between beroe & kurava.
Both have examples in which the submarginal spots may be broad or narrow.
It is ,much closer to kurava.
Note the kurava male also have the dark striae poor but not as obscure as in beroe.

For kurava, larger spots; FW band intact & straight (usually broken in beroe often in middle) FW costa spot above inner band (absent or vestigial in beroe).
N.kurava with poor dark striae.

For beroe :dark striae almost obsolete; wingbases slightly darker ( note brownish white striae)
