Glaw and Vences also list another not-yet-described species that they call Mantidactylus sp. aff. betsileanus "slow calls" that also lives at Ranomafana and is indistinguishable in the field but for some glands on the bottom of the hind legs of the males. Since I didn't turn the frog over to check its femoral glands, I'll never know which one I saw, assuming it's not some completely different species.
Here is a list of all the reptiles and frogs I saw on this trip to Madagascar.
