Mantidactylus albofrenatus
—
Eastern Madagascar Frog

This distinctive little frog is closely related to Mantidactylus opiparis, but lives further north. It's also remarkably similar to the not-as-closely-related Mantella betsileo, and lives in the same area.
Here is a list of all the reptiles and frogs I saw on this trip to Madagascar.
