Lysapsus limellum Cope, 1862, Proc. Acad. Nat. Sci. Philadelphia, 14: 155. Holotype: "Mus. Smithsonian [USNM] (No. 5495)"; now lost according to Duellman, 1977, Das Tierreich, 95: 197. Type locality: "Paraguay. Taken on _____ river". Corrected to Río Curumba, Paraguay [= Corumbá, on Rio Paraguai, Mato Grosso do Sul, Brazil] by Cope, 1862, Proc. Acad. Nat. Sci. Philadelphia, 14: 351.

Hyla quadrilineata Steindachner, 1864, Verh. Zool. Bot. Ges. Wien, 14: 262. Nomen nudum. Coined as a synonym of Lysapsus limellum and attributed to Natterer.

Podonectes palmatus Steindachner, 1864, Verh. Zool. Bot. Ges. Wien, 14: 262. Nomen nudum provided originally as a synonym of Pseudis minuta and attributed to Fitzinger. (Savage and Carvalho, 1953, Zoologica, New York, 38: 194, placed Podonectes palmatus in the synonymy of Lysapsus limellum based on examination of Steindachner's illustrations, specimens of Lysapsus limellum Cope, which must be considered to be types.)

Tadpole morphology described by Kehr and Basso, 1990, Copeia, 1990: 573–575. See comment by De la Riva, Köhler, Lötters, and Reichle, 2000, Rev. Esp. Herpetol., 14: 51-52, who discussed taxonomic confusion in Bolivia and the likelihood of this nominal species being a composite. Achaval and Olmos, 2003, Anf. Rept. Uruguay, ed. 2: 36, provided a brief account and photograph for the Uruguay population. Brusquetti and Lavilla, 2006, Cuad. Herpetol., 20: 10, briefly discussed the range in Paraguay. Vera Candioti, 2007, Zootaxa, 1600: 1–175, reported on detailed larval morphology. França and Venâncio, 2010, Biotemas, 23: 71–84, provided a record for the municipality of Boca do Acre, Amazonas, with a brief discussion of the range; presumably these specimens have been reidentified. Santana, Queiroz, Wanderley, São Pedro, Leite, and Garda, 2013, Amphibia-Reptilia, 34: 201–215, reported on tadpole morphology and advertisement call. Weiler, Núñez, Airaldi, Lavilla, Peris, and Baldo, 2013, Anf. Paraguay: 69, provided a brief account, image, and dot map for Paraguay. Affonso, Cafofo, Delariva, Karling, and Lourenço-de-Moraes, 2014, Check List, 10: 878–882, provided a record for the state of Paraná, Brazil. See account by Maneyro, Langone, and Carreira, 2019, in Maneyro, Langone, and Carreira (eds.), Libro Rojo Anf. Rept. Uruguay: 59–63, for Uruguay. Laufer, Gobel, Kacevas, Lado, Cortizas, Carabio, Arrieta, Prigioni, Borteiro, and Kolenc, 2021, Amph. Rept. Conserv., 15 (2: e290): 228–237, provided new records for Uruguay and discussed conservation status.
