Comment

In the Eleutherodactylus inoptatus group, according to Schwartz, 1965, Bull. Mus. Comp. Zool., 132: 479-508, who recognized four subspecies, now considered species (including Eleutherodactylus aporostegus, Eleutherodactylus bothroboans, Eleutherodactylus ruthae tychaethrous. Hedges and Thomas, 1987, Herpetologica, 43: 269–279, discussed the advertisement call. Powell, 1993, Herpetol. Rev., 24: 135–137, suggested that Eleutherodactylus ruthae aporostegus and Eleutherodactylus ruthae tychaethrous warranted binominal status. In the more exclusive Eleutherodactylus (Eleutherodactylus) auriculatus section, Eleutherodactylus ruthae group of Hedges, 1989, in Woods (ed.), Biogeograph. W. Indies: 329. In the Eleutherodactylus (Pelorius) ruthae group, according to Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 232. In the Eleutherodactylus (Pelorius) ruthae species series of Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 86, and of Padial, Grant, and Frost, 2014, Zootaxa, 3825: 131. See map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 377. Henderson and Powell, 2009, Nat. Hist. Rept. Amph. W. Indies: 76, summarized the natural history literature. Ríos-López, 2023, In Rios-Lopez and Heatwole (eds.), Conserv. Biogeograph. Amph. Caribb.: 218–262, discussed the systematic history and its exclusion from the list of Haitian species due to those populations being named as other species.
