Abstract 
The montane agamid lizard Japalura austeniana (Annandale, 1908), is rare and is distributed across parts of the eastern Himalayas of India and China. Support from molecular and morphological data provides evidence for the existence of a species complex in the populations referred to that binomen, and we here describe a morphologically cryptic allied new species. Evidence from molecular data suggests the presence of additional undescribed species across the distribution of that species complex. Elevation might be the restricting factor for gene flow explaining most of the diversification of that montane species complex across the Himalayas.

Japalura mictophola sp. nov. 

Diagnosis. A large-sized Japalura, reaching SVL of 92.9 mm with heterogeneous dorsum scalation and an exposed tympanum. Body laterally compressed and ventral scales subequal. Four large supra-tympanic scales and the males bear a distinct vertebral crest. Supra-tympanic scales are not in contact with orbital scales and are separated by two medium-sized smooth scales.

Etymology. The specific epithet is a combination of two words, the Greek word miktós μικτός’ meaning mixed, and the word phola (=scales) referring to the mixed (heterogeneousscales on the dorsum of the species.
