It is known that there are two different species related to
A. Diplotaenia, one is A. Diplotaenia from Rio Negro, Brasil (A128)
another one is A. cf. Diplotaenia Orinoco (from Venezuela) (A129);
I could feel that there are some differences from the publications
BUT i really could not tell precisely. May some friends help point out
the specific points of difference in terms of the fish's appearance for
identification purpose? Thanks much.
