You "A. juruensis" is definitely not A. juruensis. It is either A. cacatuoides or A. sp. Black-chin/Scwarzkinn. I can't say for certain because the diagnostic features either don't show or are out of focus on your fish. If your fish has has a spot on the caudal peduncle that is completely separate from the lateral band, and a wide black margin below the lower lip and a relatively broad black stripe running down the throat, then it's Black-chin. Otherwise it's A. cacatuoides.
I agree with Patrick1, it's probably A. paucisquamis. Although the dark abdominal markings aren't visible, the dorsal fin seems lower than that of A. mendezi.
