Mantidactylus sp unidentified species
The 2nd edition of Glaw and Vences placed these frogs in Mantidactylus grandidieri. Due to genetic differences, the 3rd edition places these frogs in a closely related undescribed species instead, referred to as Mantidactylus sp. aff. grandidieri "North". And then in 2020, a study on this group of frogs determined that Mantidactylus grandidieri does in fact live in this area, but so does a closely related and very similar-looking new species called Mantidactylus radaka. I am hoping to find out more about how to distinguish them.

These are relatively large, nocturnal frogs usually found in the water.

Here is a list of all the reptiles and frogs I saw on this 2007 trip to Madagascar.
