Abstract
The genus Ptyctolaemus (Peters, 1864) has a restricted distribution in northeast India, Indo-Burma and Indochina region. Ptyctolaemus currently includes six nominal species. Previous molecular studies suggested the presence of a genetically distinct lineage from northern Myanmar. I studied a historic series of Ptyctolaemus specimens collected from Myanmar housed at the Natural History Museum in London (n=29) and the California Academy of Sciences (n=17) in the USA. The specimens collected from Kachin State in northern Myanmar are morphologically distinct from the currently recognised species and are described here as a new species. The addition of another new species of Ptyctolaemus highlights the underestimated diversity of agamid lizards in the Indo-Burma biodiversity hotspot. An identification key to the species in the genus Ptyctolaemus is provided herein.
