A new species of small, insular, forest floor skink, Sphenomorphus perhentianensis sp. nov., is described from Pulau Perhentian Besar of the Perhentian Archipelago, Peninsular Malaysia. This species is differentiated from all other 36 Sundaland species of Sphenomorphus based on a unique collection of morphological and colour pattern characteristics. These unique characteristics include a snout-vent length of 30.0 mm, 29 midbody scale rows, smooth as opposed to striated dorsal scales, 65 paravertebrals, 61 ventrals, 4 supraoculars, parietals contacting the posterior-most supraocular, 1 medially projecting superciliary scale, 2 loreals, 6 supralabials and infralabials, 10 lamellae beneath the fourth toe, smooth subdigital lamellae, enlarged preanal scales, no body bands, a dark brown, diffuse, dorsolateral stripe extending to just past the axilla, a cream coloured dorsolateral stripe on the nape and anterior-most portion of the body, and no cream coloured postorbital stripe. The discovery of a second endemic reptile in the Perhentian Archipelago underscores the unrealized biodiversity of its herpetofauna. Additional works will describe two additional species from the Perhentian Archipelago.
A survey was carried out at Gunung Panti Forest Reserve, Johor from 3-7 August 2006, 2-5 June 2008, and 28-31 July 2008 to inventory the herpetofauna therein. An updated checklist for the area which incorporates findings from previous studies is provided. In total, 37 species of frogs, 1 turtle, 27 lizards, and 11 snakes have been recorded from Gunung Panti Forest Reserve, Johor.
A herpetological survey was conducted at Pulau Besar, Melaka from 10 to 12 June 2008, resulting in the discovery of five species of amphibians, nine species of lizards (including one new species of the gekkonid Cyrtodactylus) and one snake species. This report constitutes the first checklist of the herpetofauna of Pulau Besar and the Water Islands Archipelago.
