Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
This species is distinguished from C. ortegai by the finer granulation homogeneously distributed in the cephalic shield (vs. thicker and irregularly distributed in the cephalic shield, especially in the sphenotic, pterotic and parieto-supraoccipital); snout pointed anteriorly (vs. truncated anteriorly); distance between the anterior nostrils 5.1-5.9% SL (vs. 6.3-7.6% SL); distance between the posterior nostrils 5.2-6.2% SL (vs. 6.4-7.5% SL, rarely less than 6.4); caudal-fin lobes are relatively long, pointed posteriorly (vs. relatively short, rounded posteriorly (Ref. 119759).
Cross section: oval.
