A new species ofCurimata(Characiformes, Curimatidae) from Paraná system, in resistencia, Argentine

Systematics of the Neotropical characiform genus Cyphocharax Fowler (Pisces:Ostariophysi)

“…The only apparent differences in these samples involves scale counts and relative snout length. The higher counts of scales along the lateral line presented by Azpelicueta and Braga (1988) for C. gnaca reflect the fact that they included all the "scales in lateral line from supracleithrum to the end of body." Vari (1987 and herein) included in the counts of lateral line scales only those scales from the supracleithrum to the hypural joint and presented pored scales beyond that point as a separate count.…”

“…REMARKS.-The description of Curimata spilota (Van, 1987), based on specimens from the Rio Uruguay system in Brazil, was followed soon thereafter by Azpelicueta and Braga's (1988) description of C. gnaca based on nine specimens collected near Resistencia, Argentina. The increased number of dorsal-fin rays in the two forms is unique to these nominal forms in the Curimatidae.…”

“…-Morphometrics and meristics of (A) holotype of Curimala spilota (MZUSP 37133); (B) all examined specimens of Cyphockarax spilotus originating in Rio Uruguay system from which counts and measurements were taken; (C) all examined specimens of C. spilotus originating in Argentina from which counts and measurements were taken; and (D) holotype and paratypes of Curimala gnaca (specimens not examined, data taken from original description byAzpelicueta and Braga (1988)). Standard length is expressed in mm; measurements 1 to 10 are proportions of standard length; 11 to 14 are proportions of head length.…”

“…Standard length is expressed in mm; measurements 1 to 10 are proportions of standard length; 11 to 14 are proportions of head length. Counts of lateral-line scales byVari (1987) and herein taken using different methods than those used byAzpelicueta and Braga (1988) for C. gnaca (see discussion in "Remarks" in species account for Cyphocharax spilotus). See also comments in that section relative to transverse scale counts and relative length of snout.…”
