americanus, Cataphractus Bloch [M. E.] & Schneider [J. G.] 1801:107, Pl. 28 [M. E. Blochii, Systema Ichthyologiae; ref. 471] South America. Lectotype: BMNH 1853.11.12.193. Type catalog: Ferraris 2007:167 [ref. 29155]. An unneeded new name for and objective synonym of Silurus cataphractus Linnaeus 1758 (to avoid Strickland tautonomy). See Cataphractus americanus Lacepède 1803. Lectotype selected by Sabaj Pérez 2014:119, 126 [ref. 33305]. •Synonym of Acanthodoras cataphractus (Linnaeus 1758) -- (Sabaj & Ferraris in Reis et al. 2003:458 [ref. 27061], Ferraris 2007:167 [ref. 29155], Sabaj Pérez 2014:119, 124 [ref. 33305]).

americanus, Cataphractus Lacepède [B. G. E.] 1803:124, 127 [Histoire naturelle des poissons (Lacepède) v. 5; ref. 4930] America, especially the Carolinas [U.S.A.] [in error]. Lectotype: BMNH 1853.11.12.193. Type catalog: Ferraris 2007:167 [ref. 29155]. An unneeded new name for and objective synonym of Silurus cataphractus Linnaeus 1758 (to avoid Strickland tautonomy).

polygramma, Doras Kner [R.] 1853:145 [10], Pl. (fig. 1) [Sitzungsberichte der Kaiserlichen Akademie der Wissenschaften.

Later treated in Kner 1855:126-127 as Doras cataphractus.
