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).
