We report on a collection of reptiles made in southern Benin, mostly in the vicinity of Lama Forest, a relict rain forest surrounded by savannah habitats within the the so-called Dahomey gap. 48 species (3 chelonian, 20 saurian and 25 ophidian species were encountered) are listed with the respective voucher material and commented in respect to taxonomic or ecological information. Five lizard species (Agama sylvanus, Hemidactylus ansorgei, H. lamaensis n. sp., Holaspis guentheri, Varanus ornatus) and two snake species (Natriciteres variegata, Amblyodipsas unicolur) are new for the fauna of Benin, the second Hemidactylus species being even new to science. Some other species are reported from Benin for only the second time. This commented list of species collected from southern Benin is followed by a general country-wide checklist, which is based on literature data and also some unpublished records from northern Benin, among them the remarkable rediscovery of Agama gracilimembris, 9 decades after its original description from this country
