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.

The distributions of amphibians, birds and mammals have underpinned global and local conservation priorities, and have been fundamental to our understanding of the determinants of global biodiversity. In contrast, the global distributions of reptiles, representing a third of terrestrial vertebrate diversity, have been unavailable. This prevented the incorporation of reptiles into conservation planning and biased our understanding of the underlying processes governing global vertebrate biodiversity. Here, we present and analyse the global distribution of 10,064 reptile species (99% of extant terrestrial species). We show that richness patterns of the other three tetrapod classes are good spatial surrogates for species richness of all reptiles combined and of snakes, but characterize diversity patterns of lizards and turtles poorly. Hotspots of total and endemic lizard richness overlap very little with those of other taxa. Moreover, existing protected areas, sites of biodiversity significance and global conservation schemes represent birds and mammals better than reptiles. We show that additional conservation actions are needed to effectively protect reptiles, particularly lizards and turtles. Adding reptile knowledge to a global complementarity conservation priority scheme identifies many locations that consequently become important. Notably, investing resources in some of the world's arid, grassland and savannah habitats might be necessary to represent all terrestrial vertebrates efficiently.
