Help with ID

[Nik. NDR.]

Hello all,
I recently picked up a group of 5 Apistogramma bitaeniata WC from Brazil. 2 of which were clearly not A. bitaeniata, any idea which species it could be. As mentioned they were labelled as WC from Brazil, and the A. bitaeniata they arrived with was the yellow form.
I plan on breeding them if they turn out to be a pair, hence i would like an identifiation on them

Many thanks, Nik.

It's a regani-complex species. Since the male seems to show no caudal pattern, there are not many (known) possibilities. The first one that comes to my mind is A. sp. Gelbwangen/Yellow-cheeks. However, for this to be the case, the male shows too much red markings on the lower head and lacks the typical yellow color on gill-covers and anterior lower body. Maybe some more pictures of the male in different moods (e.g. aggressive, displaying ...) would be helpful.
