Okay, some in the right size range that I can't find pics of, A. anas (now called Parapteronotus hasemani), A. apurensis, A. ellesi, and A. eschmeyeri.
Yep, it's A. anas. I wasn't aware of the name change, thanks for that info! The funny thing is that I was I about to start trying to contact someone about revising it's genus, LOL.
