Evolution in karst massifs: Cryptic diversity among bent-toed geckos along the Truong Son Range with descriptions of three new species and one new country record from Laos Luu, Vinh Quang Bonkowski, Michael Nguyen, Truong Quang Le, Minh Duc Schneider, Nicole Ngo, Hanh Thi Ziegler, Thomas Zootaxa 2016 4107 2 101 140 [151,596,1091,1117] Reptilia Gekkonidae Cyrtodactylus Animalia Squamata 31 132 Chordata species phongnhakebangensis   Distribution.The group is mainly distributed in the karst forest mountains of Khammouane Province in central Laos,  C. calamei,  C. hinnamnoensis, and  C. sommerladiare restricted to Hin Nam No NPA in the southeastern Khammouane Province. C.  jarujiniand  C. teynieiare recorded from Bolikhamxay Province, while  C. pageliis only known to occur in Vientiane Province.   Remarks.The  Cyrtodactylus phongnhakebangensisgroup is very complex. Different morphological traits of the species of this group (e.g., body size, shape and number of dorsal bands, and number of precloacal and femoral pores, see Tables 7& 13) were supported by other morphological and phylogenetic analyses (see Figs. 1–5). All species of the group are adapted to karst forested formations.
