It is hard to say based on the photos. A. sp. Zwilling/Twin (= A. cf. payaminonis Peru, A. sp. Hi-fin Nijsseni 2) has extended lappets on the hard dorsal fin spines. They are similar in appearence to those on A. macmasteri. Your fish don't seem to show this. The markings on the head seem similar to Zwiling, but without better photos it is impossible to say for certain.

Thanks much Mike; i see and i also have big doubts about whether this wildcaught fish is Ap. sp. Zwilling or not.
