Class: Amphibia > Order: Anura > Family: Leptodactylidae > Subfamily: Leptodactylinae > Genus: Leptodactylus > Species: Leptodactylus fuscus

Rana virginica Laurenti, 1768, Spec. Med. Exhib. Synops. Rept.: 31. Types: Frog illustrated by Seba, 1734, Locuplet. Rer. Nat. Thesaur. Descript. Icon. Exp. Univ. Phys. Hist., 1: Pl. 75, fig. 4, by original designation. Type locality: Not designated. Considered (as Rana virginica Merrem, a subsequent usage), a synonym of Cystignathus fuscus by Günther, 1859 "1858", Cat. Batr. Sal. Coll. Brit. Mus.: 28, and (under Cystignathus typhonius) by Duméril and Bibron, 1841, Erp. Gen., 8: 402. Junior homonym of Rana virginica Laurenti, 1768.

Rana fusca Schneider, 1799, Hist. Amph. Nat.: 130. Syntypes: "Museo Lev. Vincentii", "Museo Lampiano", presumed lost; MNHNP 680 designated neotype by Heyer, 1968, Copeia, 1968: 160–162. Lynch, 1971, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 53: 186-187, noted that some of the original syntypes (location?) are still extant and without study of these, Heyer's neotype designation should not be accepted. Type locality: Implied to be from Surinam; neotype from "Surinam".

Rana typhonia Daudin, 1802 "An. XI", Hist. Nat. Rain. Gren. Crap., Quarto: 55–56. Syntypes: MNHNP 680 (2 specimens), according to Guibé, 1950 "1948", Cat. Types Amph. Mus. Natl. Hist. Nat.: 30; MNHNP 680 designated lectotype (and neotype of Rana fusca Schneider, 1799) by Heyer, 1968, Copeia, 1968: 160–162. Type locality: "Amérique meridionale"; given as Surinam by Heyer, 1978, Sci. Bull. Nat. Hist. Mus. Los Angeles Co., 29: 50. Synonymy by Duméril and Bibron, 1841, Erp. Gen., 8: 402; Heyer, 1968, Copeia, 1968: 160–162. Secondary homonym of Rana typhonia Linnaeus, 1758.

Rana virginica Merrem, 1820, Tent. Syst. Amph.: 177. Types: Based on frog illustrated by Seba, 1734, Locuplet. Rer. Nat. Thesaur. Descript. Icon. Exp. Univ. Phys. Hist., 1: Pl. 75, fig. 4 (named as Rana virginica Laurenti, 1768, although not so stated by Merrem), as well as other uses by other authors including Rana typhonia Daudin. Inasmuch as Merrem did not mention Laurenti one could consider this a nomenclatural act, although more likely this is a subsequent usage (DRF).
