These two species can be difficult to separate on the undersides.

The differences were based on the correct images in C&P4 & Fleming & are not absolute.

A. amphinuta. C&P4 plate 40/11, plate 60/1 ,& Fleming L182.
A. major. C&P4 plate 40/14, plate 60/2 & Fleming L183. (as A catori not L187 which is actually A. norda as stated in C&P4.)

Here is the correct image of A. amphimuta male upperside & underside of same individual.
Note the postdiscal spot in space 1b is V-shaped, & the band is less dislocated at vein 4.
