Squatina Duméril [A. M. C.] 1805:102, 342 Fem. Squalus squatina Linnaeus 1758. Type by subsequent designation. Appeared without Latinized species. Subsequent addition al species not researched. Type generally regarded as S. squatina, implied by tautonymy. Apparently Duméril (as a vernacular name) and later authors applied the species name angelus, with S. angelus an unneeded substitute for S. squatina. Compagno 1984:138 [ref. 6474] indicates that the type is S. vulgaris Risso 1810 by subsequent monotypy. Also appeared as new (sensu Plinius) in Billberg 1833:52 [ref. 34146] as Sqvatina; see Kullander 2016:109 [ref. 34147]. Genus name misspelled Sqatina by Cuvier 1831:290 [ref. 30378]. •Valid as Squatina Duméril 1805 -- (Krefft 1973:49 [ref. 7166], Compagno 1984:138 [ref. 6474], Bass 1986:107 [ref. 5635], Cappetta 1987:68 [ref. 6348], Paxton et al. 1989:62 [ref. 12442], Shirai 1992 [ref. 19882], Gomon et al. 1994:151 [ref. 22532], Compagno 1999:475 [ref. 25589], Mecklenburg et al. 2002:89 [ref. 25968], Compagno 2003:415 [ref. 26984], Compagno et al. 2005:56 [ref. 29145], Hoese & Gates 2006:159 [ref. 28997], Walsh & Ebert 2007:35 [ref. 29245], Castro-Aguirre et al. 2007:1031 [ref. 29408], Last & White 2008:1 [ref. 29746], White 2008:97 [ref. 30617], Stelbrink et al. 2009:[3] 397 [ref. 41378], Kriwet et al. 2010:117 [ref. 30825], Lipej & Dulčić 2010:11 [ref. 36649], Castro 2011:163 [ref. 31457], Vaz & Carvalho 2013:5 [ref. 32825], Theiss & Ebert 2013:74 [ref. 33034], Faria et al. 2014:1 [ref. 33251], Parin et al. 2014:28 [ref. 33547], Dyldin 2015:58 [ref. 34524], Pietsch & Orr 2015:16 [ref. 34694], Del Moral-Flores et al. 2016:66 [ref. 34398], Estalles et al. 2016:1 [ref. 34759], Ehemann et al. 2018:24 [ref. 36194], Fricke et al. 2018:21 [ref. 35805], Vaz & Carvalho 2018:144 [ref. 35832], Cañedo-Apolaya et al. 2021:4 [ref. 38306], Ebert et al. 2021:36 [ref. 38234], Long et al. 2021:113 [ref. 38922], Weigmann et al. 2023:1 [ref. 40290]).
