The blind snake lizard Dibamus dalaiensis ( family Dibamidae) was described from the Phnom Samkos Wildlife Sanctuary in the Cardamom Mountains of Cambodia by Neang Thy and colleagues. It is significant because it represents a new family, genus and species record for Cambodia and it raise the number of species in the family Diabamus to 23, eight of these species (34%) have been described in the 21st century.
Marcelo Sturaro and Teresa Avila-Pires described two new species of dwarf day geckos of the genus Gonotodes (family Spaheordactylidae); one from eastern Amazonia, in the states of Pará and Amapá in Brazil (Gonatodes nascimentoi), and another from central Colombia, east of the Andes (Gonatodes riveroi), both are species of the Gonatodes concinnatus complex.The describtion of these geckos raise the number of species in the genus Gonatodes to 26, nine (33%) of which have been described in the 21st century.
Skinks make up the largest family of lizards, with more than 1450 known species. Aurelien Miralles and colleagues have described Madascincus arenicola, a new skink from the sand dunes of northern Madagascar. But, also of interest their molecular analysis found two related species (M. polleni and M. intermedius) genetically distinct, but morphologically indistinguishable. Madascincus now contains 11 species, 2 of which were described in the 21st century.
Djoko Iskandar and colleagues have described Cyrtodactylus batik a new species collected from Mount Tompotika, in the Balantak Mountains of Central Sulawesi, Indonesia. This large Cyrtodactylus (up to 115 mm in body length), forms a lineage with C. wallacei and C. jellesmae that appears to be endemic to Sulawesi. This raises the number of Cyrtodactylus geckos to 139, 59 (42%) of which have been described in the 21st century.
The message here - squamates are much more diverse than previously thought.
