Rapala dieneces or R. suffusa?

[DaveChiangMai]

I find great difficulty to separate females of these two species. Is there any reliable feature?

These two species are very confusing even in the south where intermediate forms are seen .(Probably of hybrid origins).

R. dieneces :Generally brownish ;FW band mostly straight; orange crown more prominent.

R. dieneces in the north ,Thaialnd ,India.
