Montri Sumontha

et al.

ABSTRACT:

Protobothrops kelomohy sp. nov. is described
from dry evergreen forest in Chiang Mai Province, northern Thailand,
based on morphology and a molecular phylogeny. It differs from congeners
by a combination of characters…

The new discovery and other
recent findings suggest that further herpetological research is required
in the montane forest of northern Thailand and adjacent Myanmar and
Laos. Data on the natural history of the new species and an updated key
to the species of Protobothrops are provided. This is the second species of Lance-headed Pit Viper recorded from Thailand after P. mucrosquamatus.
