Calumma tjiasmantoi
—
Ranomafana Nosed Chameleon
This species was split out from Calumma nasutum in 2020.
With the recent revision of this group of big-nosed chameleons, two species are known from Ranomafana: Calumma fallax and Calumma tjiasmantoi. They are quite similar, but one way to distinguish them is to count the scales on the upper lip (supralabials). On my full-resolution copy of this image I believe I can count 17 such scales, which would indicate that this individual is C. tjiasmantoi.
