@DaLilFishie I was wondering why I hadn't heard that name before - apparently because its a provisional species not currently accepted by any taxonomy authorities. Also there are quite a few photos of latezonatus with yellower tails online, mostly younger individuals. I do note on seeing this photo again I indeed errored on the ID, the center band is not wide enough, among a couple other things. Duly noted and I'll have to keep the potential milii in mind.
@Great Argus oh, is it not accepted? I thought it was, but a quick google confirms it is not accepted. In that case, it would be accepted as A. clarkii.
