Gymnopis Peters, 1874, Monatsber. Preuss. Akad. Wiss. Berlin, 1874: 616. Type species: Gymnopis multiplicata Peters, 1874, by monotypy.
Cryptopsophis Boulenger, 1883, Ann. Mag. Nat. Hist., Ser. 5, 12: 166. Type species: Cryptopsophis multiplicatus Boulenger, 1883, by monotypy. Synonymy by Parker, 1936, Trans. Linn. Soc. London, Ser. 2, 19: 444–446; Dunn, 1942, Bull. Mus. Comp. Zool., 91: 439-540; Savage and Wake, 1972, Copeia, 1972: 680-695.
Gymnophis — Barbour, 1924, Proc. Biol. Soc. Washington, 37: 125. Incorrect subsequent spelling.
Wet Forest Caecilians (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 24).
Guatemala to Panama.
Savage and Wake, 1972, Copeia, 1972: 680–695, revised this genus and considered its distribution. Wilkinson and Nussbaum, 2006, In Exbrayat (ed.), Reprod. Biol. Phylog. Gymnophiona: 49, 64-65, diagnosed the taxon and suggested that Dermophis and Gymnopis are closest relatives on the basis of morphological and reproductive similarity, but that the monophyly of either taxon remains undocumented. See comment under Dermophis. Köhler, 2011, Amph. Cent. Am.: 33–34, provided a brief summary of natural history, a key to the species of Central America, and range maps and photographs of the species. San Mauro, Gower, Müller, Loader, Zardoya, Nussbaum, and Wilkinson, 2014, Mol. Phylogenet. Evol., 73: 177–189, provided results that suggest that either Gymnophis is paraphyletic with respect to Dermophis, or that misidentifications exist in the phylogenetic literature (relevant specimens unavailable to be examined by these authors).
