gvaza, Labrus Linnaeus [C.] 1758:285 [Systema Naturae, Ed. X v. 1; ref. 2787] "Pelago" [Cumana, Caribbean coast of Venezuela]. No types known. Spelled guaza by authors; "u" mistypset "v" in original; spelling guaza regarded as in prevailing usage. Based on a specimen from Venezuela mentioned in a letter by Pehr Löfling (1729-1756), one of the 'Linnaeus apostles'. Subsequently confused by authors with a Mediterranean serranid, which is now classified as Epinephelus marginatus (Lowe 1834). •Valid as Epinephelus guaza (Linnaeus 1758) -- (Tortonese 1973:359 [ref. 7192], Tortonese in Whitehead et al. 1986:785 [ref. 13676], Daget & Smith 1986:302 [ref. 6204], Smith 1990:700 [ref. 18227], Bauchot in Lévêque et al. 1992:666 [ref. 21590], Evseenko 1996:727 [ref. 24666] as quaza). •In genus Mycteroperca, as güaza, regarded as a nomen dubium with discussion of locality -- (Heemstra 1991:38, 41 [ref. 19323], Randall & Heemstra 1991:198 [ref. 19601] as gvasa, Heemstra & Randall 1993:188 [ref. 21042], Smith-Vaniz et al. 1999:207 [ref. 25013], Carneiro et al. 2019:243 [ref. 37250]). •Possibly the same as Mycteroperca cidi Cervigón 1966, Mycteroperca interstitialis (Poey 1860), or Mycteroperca phenax Jordan & Swain 1884 -- (Heemstra & Randall 1993:188, 264, 266 [ref. 21042]). •Nomen dubium in Mycteroperca -- (Smith Vaniz et al. 1999:207 [ref. 25013]). •Synonym of Epinephelus marginatus (Lowe 1834) -- (Bilecenoğlu et al. 2002:79 [ref. 26753] as guaza). •Regarded as of uncertain status in Mycteroperca. •Questionably in synonymy of Epinephelus marginatus (Lowe 1834) -- (Parenti & Randall 2020:74 [ref. 37354]).
