Pipa arrabali Izecksohn, 1976

Holotype: EI 5311 (destroyed by fungus, Peixoto and Gomes 2007).

Type locality: “Vila Amazônia, Município de Parintins, Estado do Amazonas, Brasil.”

Distribution: Venezuela, Guyana, Suriname, and Brazil. In Venezuela, known only from a few localities in eastern Bolívar State.

Remarks: Specimens referred previously as Pipa aspera by La Marca (1992) are in fact P. arrabali ( Trueb and Cannatella 1986) . Both species very similar, differing only by narrow or wide separation of the nostrils sensu Trueb and Cannatella (1986). Both taxa are mostly sympatric, so validity of P. arrabali is doubtful, it could be a junior synonym of P. aspera despite the morphological support offered by Trueb and Masserin (2001).
