Description:
Cetopsis fimbriata can be distinguished from
all of its congeners by the combination of the presence
of an eye, the conical teeth on the vomer and dentary,
the rounded posterior nares which is distinctly separated
from the contralateral nares by a distance greater
than the width of the posterior nares, the presence
of a dark, distal, margin along the anal fin, the
dark distal margin of the pectoral fin, the absence
of a dark humeral spot, the absence of a posteriorly-rounded,
variably-developed, bilobed patch of dark pigmentation
at the base of the caudal fin, and the presence of
46 to 48 total vertebrae, 25 to 28 total anal-fin
rays, and 20 to 22 branched anal-fin rays.
