[Herpetology • 2003] Larutia seribuatensis & L. puehensis • Two New Southeast Asian Skinks of the Genus Larutia and Intrageneric Phylogenetic Relationships

Abstract
Two  new species  of  Larutia are described, one  from Pulau Tulai, located  38  km off the southeast coast of Pahang, West Malaysia, in the Seribuat Archipelago and another from Gunung Berumput in the Pueh Mountains of Sarawak, East Malaysia. The Pulau Tulai species differs from all others in having a pair of light yellow dorsolateral stripes, light yellow markings on the head, small maximum snout-vent length (115 mm), and characteristics of nuchal banding. The Gunung Berumput species differs from all others in having radiating nuchal markings. Both  represent new  island records (Pulau Tulai and Borneo) and, based  on morphology, are members of different monophyletic species groups within Larutia
