Aspredo Scopoli [J. A.] (ex Gronow) 1777:453 Masc. Silurus aspredo Linnaeus 1758. Appeared without species; first inclusion of species under name attributed to Scopoli not researched. Fowler (MS) lists the type as Silurus batrachus Linnaeus as designated by Eigenmann 1910:380 [ref. 1224] for Aspredo Bleeker. Mees 1987:183 [ref. 11510] indicates type is by subsequent designation of Fowler 1954:39 [our ref. 1465]. Type designated by Desmarest 1856:282 [ref. 17401] is Silurus callichthys Linnaeus 1758 -- see Whitley 1939:225 [ref. 25866] but Whitley has wrong date for Desmarest. Not Aspredo Swainson 1838. Gender uncertain, treated as masculine by current authors. •Valid as Aspredo Scopoli 1777 -- (Mees 1987:183 [ref. 11510], Burgess 1989:304 [ref. 12860], de Pinna 1998:318 [ref. 23847], Ferraris 2003:861 [ref. 26999], Friel in Reis et al. 2003:262 [ref. 27061], Ferraris 2007:58 [ref. 29155], Cardoso 2010:607 [ref. 30972], Ng 2010:271 [ref. 31110]). Current status: Valid as Aspredo Scopoli 1777. Aspredinidae: Aspredininae.

Aspredo Swainson [W.] 1838:332 Masc. Aspredo gronovii Swainson 1838. Type by monotypy. Objectively invalid; preoccupied by Aspredo Scopoli 1777. Gender uncertain, treated as masculine by current authors. •Synonym of Bunocephalichthys Bleeker 1858 -- (Mees 1988:89 [ref. 6401]). •Synonym of Bunocephalus Kner 1855 -- (Friel in Reis et al. 2003:262 [ref. 27061], Ferraris 2007:58 [ref. 29155]). 1°Homonym. Current status: Synonym of Bunocephalus Kner 1855. Aspredinidae: Aspredininae.

Bunocephalichthys Bleeker [P.] 1858:329 Masc. Platystacus verrucosus Bloch 1794. Type by subsequent designation. Type designated by Jordan 1919:279 [ref. 4904]. •Valid as Bunocephalichthys Bleeker 1858 (with type of Bunocephalus Kner 1855 wrongly as B. hypsiurus) -- (Mees 1988 [ref. 6401] and Mees 1997:225 [ref. 22859]). •Objective synonym of Bunocephalus Kner 1855 -- (Burgess & Finley 1996:167 [ref. 22901], Ferraris 1991:224 [ref. 19536], Friel in Reis et al. 2003:262 [ref. 27061]).

Bunocephalus Kner [R.] 1855:95 [6] Masc. Silurus verrucosus Walbaum 1792. Type by subsequent designation. On p. 6 of separate. Type designated by Bleeker 1862:19 and 1863:118; not by elimination of all but one species by Bleeker 1858:327-329 (see Ferraris 1991 [ref. 19536]). Type not Bunocephalus hypsiurus Kner 1855 as argued by Mees 1988:88 [ref. 6401] and 1997:225 [ref. 22859] and disputed by Ferraris 1991. A petition to the ICZN probably is needed if one wishes to validate Mees' interpretation. •Valid as Bunocephalus Kner 1855 -- (Mees 1988:89 [ref. 6401], Burgess 1989:303 [ref. 12860], Malabarba 1989:145 [ref. 14217], Ferraris 1991 [ref. 19536], de Pinna 1996:65 [ref. 24146], de Pinna 1998:318 [ref. 23847], Britski et al. 1999:111 [ref. 24147] Friel in Reis et al. 2003:262 [ref. 27061], Ferraris 2007:58 [ref. 29155], Ferraris 2007:58 [ref. 29155], Cardoso 2010:607 [ref. 30972], Ng 2010:271 [ref. 31110], Carvalho et al. 2015:499 [ref. 33972], Bertaco et al. 2016:415 [ref. 34561], Esguícero et al. 2020:105 [ref. 37313]).

Chamaigenes Eigenmann [C. H.] 1910:380 Masc. Aspredo filamentosus Valenciennes 1840. Type by original designation (also monotypic). Description appeared in Eigenmann 1912:120 [ref. 1227], but available from 1910 by indication of included available species. •Synonym of Aspredinichthys Bleeker 1858 -- (Mees 1987:188 [ref. 11510], Ferraris 2007:57 [ref. 29155]).

Cotylephorus Swainson [W.] 1838:354 Masc. Cotylephorus blochii Swainson 1838 (= Platystacus cotylephorus Bloch 1794).

Cotilephorus is an incorrect subsequent spelling. Cotylophorus Agassiz 1846:102 [ref. 64] is an unjustified emendation. •Objective synonym of Platystacus Bloch 1794, which Mees 1987:175 [ref. 11510] treats as a synonym of Aspredo Scopoli 1777. •Synonym of Platystacus Bloch 1794 -- (Friel in Reis et al. 2003:264 [ref. 27061], Ferraris 2007:61 [ref. 29155]).
