Guibemantis flavobrunneus no known English name
Andasibe area, Alaotra-Mangoro region, MadagascarApril 24, 2023
no known English name (Guibemantis flavobrunneus)
These frogs look and behave a lot like Guibemantis pulcher, but I believe the yellow (rather than green) base color is enough to distinguish them. Another candidate is Guibemantis cf. albolineatus "Andasibe". Hopefully a Madagascar frog expert will clarify this on iNaturalist eventually.

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