furcatus, Pimelodus Valenciennes [A.] (ex Lesueur) in Cuvier & Valenciennes 1840:136 [Histoire naturelle des poissons v. 15; ref. 1008] Wabash River, Illinois, U.S.A. Syntypes: MNHN A-8402 (1, dry) Mississippi, A-8834 (1, dry) Wabash R. Type catalog: Bertin & Estève 1950:23 [ref. 19575] and Gilbert 1998:214 [ref. 23395] but not as a replacement name. We tentatively regard this as an unneeded substitute (or an unjustified emendation) for Pimelodus caudafurcatus Lesueur 1819 contrary to other authors, because Valenciennes indicates (p. 158) that Lesueur appears to have described this species under the name Pim. caudafurcatus. If not regarded as a new name for caudafurcatus, to agree with current usage, then the primary syntype is MNHN A.9458. Authorship should be Valenciennes, citation of Lesueur after the species name perhaps further indicating a name change. If regarded as a replacement name, then it is a synonym of Ictalurus punctatus (Rafinesque 1818). •Valid as Ictalurus furcatus (Valenciennes 1840) -- (Lee et al. 1980:439 [ref. 22416], Robison & Buchanan 1988:292 [ref. 23393], Burgess 1989:35 [ref. 12860], Tomelleri & Eberle 1990:122 [ref. 24089], Page & Burr 1991:192 [ref. 18983], Boschung 1992:65 [ref. 23239], Espinosa Pérez et al. 1993:26 [ref. 22290], Etnier & Starnes 1993:305 [ref. 22809], Jenkins & Burkhead 1994:533 [ref. 21581], Warren et al. 1994:132 [ref. 25557], Knight & Hastings 1994:149 [ref. 25560], Stauffer et al. 1995:211 [ref. 23376], Cross & Collins 1995:147 [ref. 23394], Mettee et al. 1996:389 [ref. 25836], Greenfield & Thomerson 1997:78 [ref. 22947], Murdy et al. 1997:93 [ref. 23144], Gilbert 1998:214 [ref. 23395], Fuller et al. 1999:200 [ref. 25838], Lyons et al. 2000:66 [ref. 26594], Moyle 2002:218 [ref. 26449], Nelson et al. 2004:81 [ref. 27807], Miller & Robison 2004:230 [ref. 27931] with author as Lesueur, Boschung & Mayden 2004:334 [ref. 27995] with author as Lesueur, Miller et al. 2006:161 [ref. 28615], Scharpf 2006:15 [ref. 30386] with author as Lesueur, Ferraris 2007:207 [ref. 29155], Rodiles-Hernández et al. 2010:67 [ref. 31022], Minckley & Marsh 2009:220 [ref. 31114] with author Lesueur, Ruiz-Campos et al. 2009:38 [ref. 40808], Page & Burr 2011:343 [ref. 31215], Page et al. 2013:83 [ref. 32708], Robins et al. 2018:163 [ref. 35886], Lorenzoni et al. 2019:253 [ref. 37108], Bagley et al. 2023:316 [ref. 41241], Page et al. 2023:79 [ref. 40505], Pérez-Rodríguez et al. 2023:9 [ref. 40420], Fricke et al. 2024:197 [ref. 41622], Quintana 2024:5 [ref. 41186]).
