The herpetofauna of the Bijagós archipelago, Guinea-Bissau (West Africa) and a first country-wide checklist

摘要

An annotated checklist of amphibians and reptiles from the Bijagós archipelago (Guinea-Bissau) with com- ments on the species' distribution, systematics and natural history traits is presented here for the first time. During two field surveys 13 anurans and 17 reptile species were recorded from the archipelago of which several species represent either first records for the islands, i.e., Silurana tropicalis, Hemisus g. guineensis, Leptopelis viridis, Hemidactylus an- gulatus, Chamaeleo gracilis, Trachylepis perrotetii, Philothamnus heterodermus, Toxicodryas blandingii, Naja melanoleuca and Thelotornis kirtlandii or first country records, i.e., Amietophrynus maculatus, Ptychadena pumilio, P. bibroni, Phrynobatrachus calcaratus, P. francisci, Leptopelis bufonides, Hyperolius occidentalis, H. nitidulus, H. spatzi, Kassina senegalensis and Thrasops occidentalis. Species diversity reflects savanna and forest elements and a complete herpetofaunal checklist of the country is provided.
