Comment

Barrio-Amorós, 1999 "1998", Acta Biol. Venezuelica, 18: 58, expected this species to be found in the Maracaibo Basin of Venezuela. Infante-Rivero, Rojas-Runjaic, and Barrio-Amorós, 2006, Herpetol. Rev., 37: 102–103, subsequently provided a voucher for the Maracaibo Lake drainage. Köhler, 2011, Amph. Cent. Am.: 289, provided a brief summary of natural history and provided a range map and photograph for this species (as Nelsonophryne aterrima). Flores, Peña, and Rivas, 2017, Herpetol. Rev., 48: 118–119, provided a range extension to Cerro Hoya National Park, Mariato District, Veraguas, Panama, and discussed the range. See Barrio-Amorós, Rojas-Runjaic, and Señaris, 2019, Amph. Rept. Conserv., 13 (1: e180): 103, for comments on range and literature. See Jowers, Othman, Borzée, Rivas-Fuenmayor, Sánchez-Ramírez, Auguste, Downie, Read, and Murphy, 2021, Organisms Divers. Evol., 21: 189–206, for discussion of molecular phylogenetics and identification of this species and a provisional range map. Kovacs and Nordseth, 2021, Herpetol. Rev., 52: 342, provided records from Pedasi and Tonosi Districts, Azuero Peninsula, Panama. Vargas and Barrio-Amorós, 2023, Reptiles & Amphibians, 30: 1–2, reported (photo voucher only) the species from Mango de Laurel, Corredores, Puntarenas, Costa Rica (08°27′17.93″N 82°54′37.58″W, 19 m elevation). In the Elachistocleis surinamensis group of Novaes-e-Fagundes, Lyra, Loredam, Carvalho, Haddad, Rodrigues, Baldo, Barrasso, Loebmann, Ávila, Brusquetti, Prudente, Wheeler, Orrico, and Peloso, 2023, Zool.
