Apantesis ID pointers - not sure that wing shape will help either - this example is same moth as previous

Species Apantesis vittata - Banded Tiger Moth - Hodges#8170
Harnessed Tiger Moth (A. phalerata) forewing is virtually identical to A. vittata but hindwing is usually more yellowish than reddish, with little or no black edging.

Remarks
There is no 100% consistent diagnostic characteristic in wing maculation or spots/no spots on the patagia (the "collar"), to reliably distinguish nais/carlotta/phalerata/vittata. The only full-proof method is dissection and examination of genitalia (the exception is in male phalerata, in which the valve is easily distinguished by its longer, up-curved apex. So one could brush the scales away from the last sternite and see it without dissection. The nais/carlotta/vittata group have rather blunt and rounded apices of the valve.)

However, within this group, using the sum of typical (although not necessarily diagnostic) characteristics, can allow for a reasonably probable species ID.
