Highighted items on the list are where Cnesterodon pirai may be found.
Remarks The stream where the new species lives is narrow (2 m wide on its widest section) and shallow, with falls about 80 cm depth, and moderately slow current. It is a tributary of the Cuña-Pirú stream (above Salto Encantado, a fall with 40 m depth); the creek only has 700 m from its headwaters to the confluence with Cuñá-Pirú. The rocky stream bed, covered by detritus over 50% of its surface, presents small pools and glides. Cnesterodon pirai was especially found forming schools of juveniles and adults in pools (Ref. 82179).
