Powell, 1993, Herpetol. Rev., 24: 135–137, suggested that Eleutherodactylus ruthae tychaethrous warranted binominal status. In the Eleutherodactylus (Pelorius) ruthae species series of Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 86 (who formalized recognition of this taxon as a species), and of Padial, Grant, and Frost, 2014, Zootaxa, 3825: 131. Henderson and Powell, 2009, Nat. Hist. Rept. Amph. W. Indies: 80, summarized the natural history literature.
