Ranomafana Nosed Chameleon (Calumma tjiasmantoi)
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.

It wouldn't be Ranomafana without some Ranomafana Nosed Chameleons now, would it?

Here is a list of all the reptiles and frogs I saw on this 2023 trip to Madagascar.

I think these are all Calumma tjiasmantoi, but I wouldn't be shocked to discover that some of them are Calumma fallax instead.
