You are too generous with your praises.
I appreciate the fact you brought the Halpe this time.
I suddenly realised on going thru the species that the dozen of confusing species in the Indochinese region can be ignore.
Two species mentioned in Evans H. kusala & flava both have UnH central band, yellow in flava & yellowish white in kusala are unlikely to occur in India. http://yutaka.it-n.jp/hes/91390001.html http://yutaka.it-n.jp/hes/91360001.html Correction: Both H. kusala & flava occur in NE India. (included in checklist).
The degree of overlap between FW spot 2 & 3 in H. molta is quite variable.
That in H. aucma should be little or almost none.
The UnH interneural black spots are fairly well-define with the sharper margins visible.
So it is probably H. molta.
The white cilia is more or less the same in all three species.
You may want to see pix of H. filda, molta & aucma.
Images poor.
