Difference between Vindula erota erotella and Vindula dejone chersonesia

[David Chan]

Dear Dr Seow,

I shot this Cruiser in Northern Thailand. Is it a Vindula erota erotella or Vindula dejone chersonesia and how do you differentiate them?

It is V. erota.

V. erota{Dark line on the FW tend to be lunulate(crescentic); at the upper part it is nearer the cellend at the upper 1/2 than at the lower 1/2

In V. dejone, the discal line is composed of mostly straight streaks, it is equal distance from the cellend at both upper & lower halves.
