Common Names 
SynonymCyrtodactylus zugi OLIVER, TJATURADI, MUMPUNI, KREY & RICHARDS 2008
Cyrtodactylus zugi — TALLOWIN et al. 2018 
DistributionIndonesia (New Guinea: Raja Ampat Archipelago, Papua Barat Province)

Type locality: Yakut Camp, Batanta Island, Raja Ampat Archipelago, Papua Barat Province, Indonesia (00°53.749’S, 130°38.498’E; elevation ~ 10 m).  
TypesHolotype: MZB lace 5574, adult female with entire original tail, detached at base during
collection, collected on large tree trunk in lowland rainforest. 
DiagnosisDiagnosis: Cyrtodactulus zugi sp. nov. can be distinguished from all other Melanesian Cyrtodactylus by the combination of large size (SVL up to 159 mm), robust build (HW/SVL 0.21–0.22), precloacal groove absent, subcaudal scales less than twice width of lateral and dorsal caudal scales, relatively small rounded tubercles along the lateral fold, a series of enlarged ventral tubercles present below the lateral fold, enlarged tubercles on ventral surface of head confined to the region around the angle of the lower jaw, moderate number of enlarged precloacal and femoral scales (>28) arranged in straight or almost straight series, and dorsal colouration consisting of 3–4 very dark greyish-brown indistinct dorsal blotchess between the head and tail.
CommentDistribution: C. zugi is the second species of Cyrtodactylus known with certainty only from the Raja Ampat Islands.

Similar species: The morphology of the new species places it within the C. loriae group and suggests that it is closely related to Cyrtodactylus irianjayaensis. 
EtymologyNamed in honour of George Zug from the Smithsonian Institution in recognition of his vast contributions to our knowledge of the systematics and ecology of the herpetofauna of Melanesia and Asia. For biographical details see Mitchell 2018 and Zug in Schneider & Trueb 2021).
