Cnesterodon hypselurus Lucinda & Garavello, 2001: 29 View in CoL , fig. 5 and 6. Type -locality: Brasil. Paraná. rio Cilada, bridge of road BR 151, rio Paranapanema drainage, Jaguariaíva.

Diagnosis. Cnesterodon hypselurus is diagnosed by the following autapomorphies: (1) presence of a longitudinal dark brown band along flank. (2) bony style of ray 3 of gonopodium of fully developed mature males curly-bracket shaped ( Lucinda & Garavello, 2001; fig. 6).

Furthermore, C. hypselurus is readily distinguished from C. omorgmatos and C. raddai by dark brown blotches along body sides (forming bars vs. circular or irregular, respectively). Cnesterodon hypselurus is distinguished from C. decemmaculatus , C. brevirostratus , and C. iguape by dark bars of body very elongate reaching dorsal and ventral profiles, covering more than four scales in a transverse row (vs. dark bars on sides of body, mostly confined to midline, covering less than three scales in a transverse row, never extending to dorsal and ventral profiles). The absence of small scales covering lateral and ventral region of body below pectoral fin and the pointed snout also differentiate C. hypselurus from C. brevirostratus . Cnesterodon hypselurus is distinguished from C. septentrionalis , C. omorgmatos , and C. decemmaculatus , by the number of epipleural ribs (10-12 vs. 6 in C. septentrionalis , 7 or 8 in C. omorgmatos and C. decemmaculatus ).

Distribution. Cnesterodon hypselurus is known from rio Cilada, rio Lambari and rio Guaricanga in upper rio Paranapanema basin, rio Paraná drainage ( Fig. 1 View Fig ).
