Anomaloglossus


Anomaloglossus is a genus of frogs in the family Aromobatidae. The genus is endemic to the Guiana Shield in northern South America. It used to be placed in the family Dendrobatidae, and is still placed in that family by some sources. The name of the genus, from the Greek anomalos and glossa, refers to the unusual tongue bearing the median lingual process, the only unambiguous phenotypic synapomorphy of this genus.

Description

Anomaloglossus are characterized by cryptic dorsal coloration. Dorsal skin is posteriorly granular. The toes are webbed, ranging from basal to extensive. The fingers have weakly expanded discs.

The tadpoles can be either exotrophic or endotrophic.
