Abstract A new species of the endemic scincid lizard genus Lankascincus from the Rakwana hills of Sri Lanka, is described. The new species is distinguished from its congeners by possessing the following combination of characters: maximum SVL less than 35.0 mm, prefrontals in broad contact, seven supralabials, last supralabial scale split, 24 mid-body scale rows, 46–48 paravertebrals, 49–51 ventrals, 13–16 lamellae on fourth toe, and a conspicuous dark brown band from snout to mid-tail, gradually fading posteriad. The number of palpebral scales around eye is used as a meristic character in the genus Lankascincus for the first time.

Abstract We examined the syntype series of Eutropis rudis (6 specimens) collected from Sumatra and Borneo, currently deposited at the Natural History Museum, London. We observed that the type series is composed of two species. In order to stabilize application of the name, we designate a lectotype for E. rudis from Sumatra. Mabuya lewisi, described based on a specimen from Borneo, is resurrected as a valid species of Eutropis and redescribed. Based on morphology and geographic distribution, we describe a new species of this complex from Great Nicobar Island with two specimens deposited at the Zoological Survey of India (ZSI), Kolkata.

Abstract The Modigliani’s nose-horned lizard, Harpesaurus modiglianii Vinciguerra, 1933, is one of the rarest lizards in the world, known only from its single type specimen collected in 1891, from North Sumatra, Indonesia. During explorations of the forests surrounding Lake Toba and its caldera, we discovered a population of H. modiglianii at an elevation of 1,675 m a.s.l., and provide the first data on its habitat. We here re-describe the species based on an examination of its type and new material, and provide an English translation of the complete original description which was originally written in Italian.

Abstract We reassessed the systematic position of the ranid frog Hylorana (=Hylarana) nicobariensis that, owing to its uncertain phylogenetic position and lack of clear morphological characterisation, has lately been allocated to various Asian and African frog genera such as Rana, Sylvirana, Hylarana, Amnirana, and most recently to Indosylvirana. Based on an integrative approach of both phylogenetic and morphological affinities, we describe a new genus to accommodate Hylorana (=Hylarana) nicobariensis and redescribe the species based on new topotypic material from the Nicobar Islands.
