Anomaloglossus dewynteri is a species of frog in the family Aromobatidae. It is endemic to French Guiana.
The adult male frog measures 19.4âÂÂ20.4 mm in snout-vent length.
Scientists used to believe this population to be part of A. degranvellei.
This frog lives in rocky streams. Scientists observed it on the Itoupé massif.
Scientists saw the frog in one protected place: Parc Amazonien de Guyane.
The males sit near streams and call to the female frogs. After the eggs hatch, the male frogs carry the tadpoles to streams.
The IUCN classifies this frog as critically endangered. Although they have not directly observed the fungus Batrachochytrium dendrobatidis on any of these frogs, but their population decline mirrors that of other amphibians affected by chytridiomycosis in French Guiana. This frog has not been shown to be subject to much habitat disturbance.
