Arrabal's Surinam Toad (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 96).

Arrabal's Pipa (Kok and Kalamandeen, 2008, Intr. Taxon. Amph. Kaieteur Natl. Park: 236).

Distribution

Guyana, western Suriname, eastern Venezuela, and northern (Pará), central (Amazonia and Mato Grosso), and western (Rondônia) Brazil as far east as the state of Tocantins.

Geographic Occurrence

Natural Resident: Brazil, Guyana, Suriname, Venezuela

Comment

Barrio-Amorós, 1999 "1998", Acta Biol. Venezuelica, 18: 59, commented on the Venezuelan distribution. Zimmerman and Rodrigues, 1990, in Gentry (ed.), Four Neotropical Rainforests: 426–454, provided the first central Brazilan Amazonia record for this species. Sousa and Bernarde, 2007, Herpetol. Rev., 38: 98, provided a record for Rondonia, Brazil. Kok and Kalamandeen, 2008, Intr. Taxon. Amph. Kaieteur Natl. Park: 236–237, provided an account. Señaris Vasquez, Lampo, Rojas-Runjaic, and Barrio-Amorós, 2014, Guía Ilust. Anf. Parque Nac. Canaima: 236–237, provided a photograph and a brief account for the Parque Nacional de Canaima, Venezuela. Araújo, Haddad, Silva, and Púgener, 2016, An. Acad. Brasil. Cienc., 88: 1875–1887, provided a larval staging table. See Barrio-Amorós, Rojas-Runjaic, and Señaris Vasquez, 2019, Amph. Rept. Conserv., 13 (1: e180): 109, for comments on range and literature, noting reidentifications and doubting the distinction of this species from Pipa aspera. Silva, Carvalho, Pereira Silva, Fadel, Dantas, Brandão, and Santana, 2020, Biota Neotrop., 20 (1: e20190838): 15, reported the species in Tocantins, Brazil, and discussed the known range in detail. Fouquet, Cornuault, Rodrigues, Werneck, Hrbek, Acosta-Galvis, Massemin, Kok, and Ernst, 2022, Mol. Phylogenet. Evol., 170 (107442): 1–14, suggested on the basis of molecular analysis that nominal Pipa arrabali is composed of at least 3 species, one of which (Guyana) is more closely related to Pipa aspera than to other populations of Pipa arrabali.
