Re: C. Affinis

["Dan Katz" <dansk1 at home_com>]

Cynolebias affinis was given the species name " affinis" because it looked
so much like Cynolebias nigripinnis.  Prior to its' description, it was
designated as "Cynolebias aff. nigripinnis".
Its' proper name ( as of today, at least) is Austrolebias affinis.
