Anaxyrus speciosus (Girard, 1854)
Bufo speciosus Girard, 1854, Proc. Acad. Nat. Sci. Philadelphia, 7: 86. Syntypes: USNM 2608 (Ringgold Barracks = Rio Grande City, Starr County, Texas, USA), 2610 (Brownsville, Cameron County, Texas, USA), 2611 and 131559 (Pesquiería Grande, Nuevo León, Mexico) according to Cochran, 1961, Bull. U.S. Natl. Mus., 220: 37. Kellogg, 1932, Bull. U.S. Natl. Mus., 160: 46, mentions only three types and does not include 131559. Type locality: "valley of the Río Bravo (Rio Grand del Norte) and to be not uncommon in the province [state] of New Leon [Nuevo León, Mexico]". Restricted to "Brownsville, Cameron County", Texas, USA, by Smith and Taylor, 1950, Univ. Kansas Sci. Bull., 33: 361.
Bufo spectabilis — Peters, 1874 "1873", Monatsber. Preuss. Akad. Wiss. Berlin, 1873: 747. Incorrect subsequent spelling of Bufo speciosus Girard.
Bufo lentiginosus speciosus — Garman, 1884, Bull. Essex Inst., 16: 43, by implication.
Bufo speciosus — Garman, 1888 "1887", Bull. Essex Inst., 19: 136; Bogert, 1960, in Lanyon and Tavolga (eds.), Anim. Sound Commun.: 195, 273; provisional elevation.
Bufo compactilis speciosus — Cope, 1889, Bull. U.S. Natl. Mus., 34: 273; Smith, 1947, Herpetologica, 4: 8.
Bufo pliocompactilis Wilson, 1968, Contr. Mus. Paleontol. Univ. Michigan, 22: 95. Holotype: UMMP V55430, a near complete left frontoparietal, by original designation. Type locality: WaKeeney, Ogalalla Formation, Trego County, Kansas, USA. [Miocene (Clarendonian) fossil.] A likely synonym of "Bufo compactilis" (in the sense of being what is now called Anaxyrus speciosus) by Sanchíz, 1998, Handb. Palaeoherpetol., 4: 126.
Anaxyrus speciosus — Frost, Grant, Faivovich, Bain, Haas, Haddad, de Sá, Channing, Wilkinson, Donnellan, Raxworthy, Campbell, Blotto, Moler, Drewes, Nussbaum, Lynch, Green, and Wheeler, 2006, Bull. Am. Mus. Nat. Hist., 297: 363.
Bufo (Anaxyrus) speciosus — Fouquette and Dubois, 2014, Checklist N.A. Amph. Rept.: 308. See comment under Bufonidae regarding how this arrangement is part of a a system that requires widespread paraphyly.

Comment
In the Bufo cognatus group of Blair, 1972, Evol. Genus Bufo: 349. See comment under Bufo cognatus. Older literature confused this species with Anayxrus cognatus, Anayxrus mexicanus, and Anayxrus compactilis. Removed from the synonymy of Anayxrus compactilis (as Bufo) by Bogert, 1960, in Lanyon and Tavolga (eds.), Anim. Sound Commun.: 195, 273, where it had been placed (as Bufo spectabilis) by Peters, 1874 "1873", Monatsber. Preuss. Akad. Wiss. Berlin, 1873: 747 (although this had been disputed by Garman, 1888 "1887", Bull. Essex Inst., 19: 136). See Rogers, 1972, Copeia, 1972: 381–383, for discussion of morphological distinctiveness from other members of its species group. Cocroft and Ryan, 1995, Animal Behav., 49: 283–303, discussed advertisement call in an evolutionary context. Stebbins, 2003, Field Guide W. Rept. Amph., Ed. 3: 215–216, provided a brief account, figure, and map. Lemos-Espinal, 2007, Anf. Rept. Chihuahua Mexico: 41–42, provided an account (as Bufo speciosus) for Chihuahua, Mexico. Lemos-Espinal and Smith, 2007, Anf. Rept. Coahuila México: 38–39, provided an account (as Bufo speciosus) for Coahuila, Mexico. Oliver-López, Woolrich-Piña, and Lemos-Espinal, 2009, Fam. Bufonidae Mex.: 48–50, provided an account. Farr, Lazcano, and Lavín-Murcio, 2013, Herpetol. Rev., 44: 633, provided records for Tamaulipas, Mexico. Dayton and Painter, 2005, in Lannoo (ed.), Amph. Declines: 435–436, andDodd, 2013, Frogs U.S. and Canada, 1: 152–155, provided accounts that summarized relevant literature. Elliot, Gerhardt, and Davidson, 2009, Frogs and Toads of N. Am.: 146–147, provided an account, photos, and advertisement call. Altig and McDiarmid, 2015, Handb. Larval Amph. US and Canada: 184, provided an account of larval morphology and biology. Painter, Stuart, Giermakowski, and Pierce, 2017, Western Wildlife, 4: 35, commented on the status and county range in New Mexico, USA. Bassett, 2023, Reptiles & Amphibians, 30(e18486): 1–18, provided an updated county distribution map for Texas, USA.
