KNODUS Eigenmann, 1911 View in CoL

KM Ferreira

Knodus Eigenmann, 1911b:216 . Type species: Knodus meridae Eigenmann, 1911 . Type by monotypy. Gender: Masculine. Additional comments: Also appeared as new genus in Eigenmann, 1918b:114 with type given as Bryconamericus breviceps Eigenmann (date of publication and type species was later clarified by Eigenmann, Myers, 1929:526).

Bryconadenos Weitzman, Menezes, Evers, Burns, 2005:334 View in CoL . Type species: Bryconadenos tanaothoros Weitzman, Menezes, Evers, Burns, 2005 View in CoL . Type by original designation. Gender: Masculine. Additional comments: Considered a synonym of Knodus Eigenmann, 1911 View in CoL by Thomaz et al., 2015:20, considered a valid genus considered sister-taxon of Phallobrycon View in CoL within the tribe Diapomini by Ferreira et al., 2021.

He also mentioned that Eigenmann, 1914:7 had previously suggested that B. beta could be a synonym of B. alpha .
