The genus Cordylancistrus ZBK was described by Isbrücker (1980) with C. torbesensis (Schultz, 1944) as the type and only species. Isbrücker (1980: 48) stated that: “ Cordylancistrus ZBK seems related to the genus Lasiancistrus , from which it can easily be distinguished by its exceptionally wide head”. Pérez and Provenzano (1996) described C. perijae ZBK , indicated some external characters that define the genus Cordylancistrus ZBK and postulated a close relationship between Cordylancistrus ZBK and the genus Chaetostoma ZBK . They also presented a biogeographic hypothesis on the distribution of C. torbesensis and C. perijae ZBK . Isbrücker (2001) included in the genus Cordylancistrus ZBK the species: C. daguae , C. perijae ZBK , C. platycephalus , C. platyrhynchus and C. torbesensis , without comment. Fisch-Muller (2003) listed the same five species of Cordylancistrus ZBK . Armbruster (2004) indicates that species of the genera Chaetostoma ZBK , Leptoancistrus ZBK , Dolichancistrus ZBK and Cordylancistrus ZBK together form a monophyletic group, but that Cordylancistrus ZBK is apparently not monophyletic and pointed out that only one basic difference (naked snout) was found between the species of Chaetostoma ZBK and the species assigned to Leptoancistrus ZBK , Dolichancistrus ZBK and Cordylancistrus ZBK . He transferred Cordylancistrus platyrhynchus to the genus Chaetostoma ZBK and presented a new diagnosis for Chaetostoma ZBK while maintaining the rest of the genera. Apparently, the recognition of genera and the assignment of species to a genus are controversial. Transitory, we agree with Isbrücker (2001) and Fisch-Muller (2003) and accept five species in the genus Cordylancistrus ZBK .
