paleatus, Callichthys Jenyns [L.] 1842:113 [The zoology of the voyage of H. M. S. Beagle; ref. 2344] Laguna del Potrero, Maldonado, Uruguay, 34°50'28"S, 55°08'43"W. Lectotype: BMNH 1917.7.14.18 [ex Cambridge Mus.]. Paralectotypes: BMNH 1917.7.14.19 and 19a [ex Cambridge Mus.] (2) South America. Type catalog: Ferraris 2007:122 [ref. 29155]. Lectotype selected by Nijssen & Isbrücker 1980:204 [ref. 6910]. But Knaack 2007:23 [ref. 29220] regarded BMNH 1917.1.14.18 as not the lectotype, finding the lectotype to be lost; he selected BMNH 1917.7.14.19 as the neotype (following Art. 75). Knaack 2008:15 [ref. 29618] retracted his neotype designation and supported the lectotype designation by Nijssen & Isbrücker. Callichthys punctatus Valenciennes 1834 is the senior synonym of C. paleatus Jenyns 1842, but C. paleatus is a nomen protectum when in Corydoras due to secondary homonymy of C. punctatus (see Grant 2018:26 [ref. 36057]).
