Cnesterodon omorgmatos Lucinda & Garavello, 2001: 126 . fig. 3 and 4. Type -locality: Brasil, Paraná, rio das Torres, rio Iguaçu basin, Pinhão.

Diagnosis. Cnesterodon omorgmatos is distinguished from its congeners, except C. decemmaculatus , by the number of epipleural ribs (7 or 8 vs. 6 in C. septentrionalis and 10-12 in remaining species). Cnesterodon omorgmatos differs from its congeners, but C. raddai by the presence of circular or irregular dark brown blotches along body sides. Cnesterodon omorgmatos is distinguished from C. raddai by the general size of adults (18.7-24.8 mm [adult males], 20.0- 30.5 mm [adult females] vs. 14.6-17.0 mm [adult males], 17.1-23.2 mm [adult females], respectively) and by its color pattern (six to nine dark brown circular to irregular blotches or vertical wide bars along body sides vs. two to four clearly rounded dark spots along body sides, respectively).

Distribution. Cnesterodon omorgmatos is known solely from the type-locality in the rio Iguaçu basin ( Fig. 1 ).
