Leptodactylus wagneri (Peters, 1862)

Class: Amphibia > Order: Anura > Family: Leptodactylidae > Subfamily: Leptodactylinae > Genus: Leptodactylus > Species: Leptodactylus wagneri

Plectromantis wagneri Peters, 1862, Monatsber. Preuss. Akad. Wiss. Berlin, 1862: 232. Type(s): ZSM 1080/0, lost, according to Heyer, 1970, Contrib. Sci. Nat. Hist. Mus. Los Angeles Co., 191: 19, and Glaw and Franzen, 2006, Spixiana, München, 29: 174; neotype designated by Heyer, 1970, Contrib. Sci. Nat. Hist. Mus. Los Angeles Co., 191: 19, as NHRM unnumbered (holotype of Eleutherodactylus leptodactyloides; NHRM 1945, according to W. R. Heyer, personal commun.). This neotype designation considered invalid by Heyer, 1994, Smithson. Contrib. Zool., 546: 78, who considered Leptodactylus leptodactyloides and Plectromantis wagneri to represent different species. QCAZ-A 26219 designated neotype by Carvalho, Fouquet, Lyra, Giaretta, Costa-Campos, Rodrigues, Haddad, and Ron, 2022, Syst. Biodiversity, 20 (1: 2089269): 16. Type locality: Published originally "an den Westseite der Anden in Ecuador" but data associated with lost type specimen was "Pastassathal" (= Pastaza Valley), Ecuador; by neotype designation of Heyer, 1970, Contrib. Sci. Nat. Hist. Mus. Los Angeles Co., 191: 39, the type locality became Pastaza, Ecuador, on the east side of the Andes. With the rejection of the neotype designation (see above) the type locality reverts to the original statement by Peters. The QCAZ neotype is from "outskirts of Puyo (1.443070°S, 77.996660°W; 954m elevation), in the province of Pastaza, central Ecuador".

Comment

In the Leptodactylus melanonotus group, Leptodactylus wagneri-Leptodactylus podicipinus complex. Duellman, 1978, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 65: 112–114, provided a brief account and characterization of the call and tadpole. Zimmerman, 1983, Herpetologica, 39: 235–246, and Zimmerman and Bogart, 1984, Acta Amazonica, 14: 473–520, reported on vocalization. See account by Heyer, 1994, Smithson. Contrib. Zool., 546: 104–105. Rodríguez and Duellman, 1994, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 22: 70, provided a brief account for the Iquitos region of northeastern Peru. De la Riva, Köhler, Lötters, and Reichle, 2000, Rev. Esp. Herpetol., 14: 41, noted that this species does not occur in Bolivia. 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. Fouquet, Gilles, Vences, Marty, Blanc, and Gemmell, 2007, PLoS One, 10 (e1109): 1–10, provided molecular evidence that this is a species complex. Bernarde, Machado, and Turci, 2011, Biota Neotrop., 11: 117–144, reported specimens from Reserva Extrativista Riozinho da Liberdade, Acre, Brazil, although this requires confirmation. In the Leptodactylus melanonotus species group of de Sá, Grant, Camargo, Heyer, Ponssa, and Stanley, 2014, S. Am. J. Herpetol., 9(Spec. Issue 1): 1–123, and who provided a summary of relevant literature (adult morphology, identification, and range) on p. 87–88. Zimmerman, 1983, Herpetologica, 39: 235–246, reported on advertisement call. Metcalf, Marsh, Torres Pacaya, Graham, and Gunnels, 2020, Herpetol. Notes, 13: 753–767, reported the species from the Santa Cruz Forest Reserve, Loreto, northeastern Peru. Carvalho, Fouquet, Lyra, Giaretta, Costa-Campos, Rodrigues, Haddad, and Ron, 2022, Syst. Biodiversity, 20 (1: 2089269): 1–31, reported on the systematics, phylogenetics, advertisement call, and geographic distribution and habitat. Gagliardi-Urrutia, García Dávila, Jaramillo-Martinez, Rojas-Padilla, Rios-Alva, Aguilar-Manihuari, Pérez-Peña, Castroviejo-Fisher, Simões, Estivals, Guillen Huaman, Castro Ruiz, Angulo Chávez, Mariac, Duponchelle, and Renno, 2022, Anf. Loreto: 154–155, provided a brief account, photograph, dot map, and genetic barcode for Loreto, Peru. Coloma and Duellman, 2025, Amph. Ecuador. Vol. 4: 98–100, provided an account, with photographs, which summarized identification, adult morphology, systematics, natural history, distribution (including a dot map for Ecuador), conservation, and (on pp. 389–390) vocalization.
