Range extension of the rare agamid, Pseudocalotes austeniana (Annandale, 1908) (Reptilia, Sauria, Draconinae) in the East Himalaya, with comments on its ontogenetic shift

Despite its recognition since the early 1900s, the agamid lizard Pseudocalotes austeniana remains known based on 3 vouchered specimens only from the East Himalaya, and little is known about its general biology. During herpetological surveys of Tibet, China, we collected 3 specimens of P. austeniana from Medog County, southeastern Tibet, including the first juvenile specimen ever vouchered. We provide a detailed description based on new material of this enigmatic species, report on a range extension of 400 km northeastward from its type locality, its ontogenetic shift, and clutch size.
