See comment under Elachistocleis which explains context of retaining this nominal taxon as distinct from Relictivomer pearsei, even though when recognizing Elachistocleis surinamensis, Kenny regarded it as a senior synonym of Relictivomer pearsei. See Rivero, Langone, and Prigioni, 1986, Comun. Zool. Mus. Hist. Nat. Montevideo, 11: 6-7. Barrio-Amorós, 1999 "1998", Acta Biol. Venezuelica, 18: 57, commented on the Venezuelan distribution. Lavilla, Vaira, and Ferrari, 2003, Amphibia-Reptilia, 24: 279, regarded this nominal form to cover a complex of species. Murphy, 1997, Amph. Rept. Trinidad Tobago: 93-95, provided an account for Trinidad. See account for Surinam population by Ouboter and Jairam, 2012, Amph. Suriname: 278-279, who noted that all previous records of nominal Elachistocleis ovalis from Surinam are referrable to this species. See Barrio-Amorós, Rojas-Runjaic, and Señaris, 2019, Amph. Rept. Conserv., 13 (1: e180): 103, for comments on range and literature.
