Abstract:
A new species of large Cyrtodactylus is described from lowland rainforest on Batanta Island in the Raja Ampat Archipel ago, Papua Barat Province, Indonesian New Guinea. The new species can be distinguished from all other Melanesian
Cyrtodactylus by the combination of large size (over 110mm SVL), very robust build, presence of enlarged ventral tuber cles below the lateral fold and around the angle of the lower jaw only, and dorsal colouration consisting of three to four
irregular dark greyish-brown blotches. It is the second species of Cyrtodactylus known with certainty only from the Raja
Ampat Islands. The morphology of the new species places it within the C. loriae group and suggests that it is closely
related to Cyrtodactylus irianjayaensis
