Abstract

AZPELICUETA, María de las Mercedes  and  BRITSKI, Heraldo A.. Iheringichthys syi (Siluriformes: Pimelodidae), a new pimelodid species from upper Paraná basin, Brazil. Neotrop. ichthyol. [online]. 2012, vol.10, n.1, pp.45-52. ISSN 1679-6225.  https://doi.org/10.1590/S1679-62252012000100004.

We describe a new species of pimelodid catfish of the genus Iheringichthys from the upper Paraná basin, Brazil. Iheringichthys syi n. sp. is distinguished by the comparatively fine serration along the anterior margin of the pectoral-fin spine, an adpressed dorsal-fin remote from the adipose-fin origin, a large eye (23.2-31.2% of head length), narrow interorbital (16.2-23.0% of head length), long snout (42.0-51.0% of head length), long postorbital length (30.6-34.0% of head length), low adipose fin (4.8-7.8% of standard length), eye diameter 97.0-140.0% of interorbital length, and body with numerous, small dots irregularly scattered on flanks, especially marked on anterior half of flank.

Keywords : Catfishes; Neotropical region; South-East South America.
