Bottom: (left) Nuchal bands of Larutia seribuatensis ZRC 2.5088 and (right) L. trifasciata BM 3853. First nuchal band of L. seribuatensis makes contact with the posterior edge of the eye.
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.
