Amphibian and reptile dataset across different land-use types in Guinea-Bissau, West Africa

Based on 126 sampling hours of both diurnal and nocturnal standardised surveys, in addition to opportunistic surveys, these datasets comprise the first overview for amphibians and reptiles in mainland Guinea-Bissau across two seasons and different habitat types. Each of the 968 standardised and 155 opportunistic occurrences corresponds to a genus or species and is accompanied by geographic coordinates, a timestamp and, for standardised data, the land-use type. The datasets fill the distribution gaps in Guinea-Bissau of at least three species, including the frog <i>Hildebrandtiaornata</i>, the skink <i>Trachylepiskeroanensis</i> and the snake <i>Dendroaspispolylepis</i> - and include the re-discovery of the lizard <i>Latastiaornata</i> in Guinea-Bissau. Before this work, the <i>L.ornata</i> was only known from the 1938 holotype in Bafatá (ca. 60 km away from the study area) and, in 2023, from Guinea-Conakry (ca. 700 km away from the type specimen location).
