The Leptodactylus bolivianus complex has recently been assessed and determined to be comprised of three species – L. bolivianus, L. guianensis, and L. insularum (Heyer & de Sá 2011). The aim of this study is to amplify data for L. insularum that were not included in the Heyer & de Sá (2011) publication. The earlier paper based distributional data only on specimens evaluated by Heyer. Later literature searches identified further information and a greater number of localities for Leptodactylus insularum resulting in a comprehensive summary and a more precise distribution for the species.

The purpose of this paper is to summarize information for the currently understood single species Leptodactylus insularum. Pertinent literature is reviewed and summarized for biology, life history, systematics, nomenclature, conservation, and distribution.
