Abstract

We investigated diminutive day geckos (SVL < 40 mm) of the genus Cnemaspis (Cnemaspis kandiana Group) from mainland Sumatra and islands along its western margin (Nias, Siberut, Pagai, and Enggano). The assemblage includes several species based on morphological evidence, five of which we describe as new. The new species occur in the Sumatran provinces of Aceh, North Sumatra, and West Sumatra. Finally, we provide a new key and redescriptions for three previously recognized species: Cnemaspis dezwaani, Cnemaspis modiglianii, and Cnemaspis whittenorum, based on recently collected material, and clarify contradictory information concerning their original descriptions and their key under each species account.

The Gibba Toad-headed Turtle (Mesoclemmys gibba) is a wide-ranging South American species in the lowlands of the Orinoco and Amazon Basins. A relatively small-bodied species with carapace length rarely exceeding 35 cm, the nocturnal M. gibba inhabits rainforest streams, hardpan pools of shallow water in gallery forests, and Mauritia palm swamps. Diet consists primarily of small invertebrates and mollusks. Owing in part to their foul-smelling defensive musk, they are not used as food by local populations of people.
