Re: C. Affinis

[Matt Hirvonen <mdhirvon at facstaff_wisc.edu>]

Hmmm, the discussion of C. affinis has me puzzled.  I was under the 
impression that affinis was latin for "related" or "similar" and was 
applied to undescribed fishes to suggest which genus or species they were 
probably part of...  For example C.affinis would be interpreted as a 
cynolebias of undetermined lineage (which would hopefully have a location 
to differentiate it)  - another common example is A. species affinis 
Primagenium which I take to mean that this fish is not exactly like the 
type description of primagenium but is likely a close relative.

This discussion has special interest for me because in the last year I have 
aquired two species of wild caught cynolebias (astrolebias?) that were both 
labeled C. Affinis  but from 2 different locations -  Pueblo Ansina and 
Tres Cruces (Argentina or Uraguay?).  They are similar looking fish but not 
identical!   Can someone tell me positively if the affinis name is 
incorrectly applied to these species?  If it is wrong, should I drop the 
"affinis" and call them by their location only - i.e. C. Pueblo Ansina?  I 
will be in a position to show and distribute the offspring of these fish in 
the near future.  My biggest concern is how to list/label them, I would 
hate to pass on an incorrect name, and contribute to the nomenclature mess 
that currently exists.

PLEASE HELP
