30 species (see text) Anomaloglossus is a genus of frogs in the family Aromobatidae.

[2][3][4] The genus is endemic to the Guiana Shield in northern South America.

[6] The name of the genus, from the Greek anomalos (=irregular, unusual) and glossa (=tongue), refers to the unusual tongue bearing the median lingual process, the only unambiguous phenotypic synapomorphy of this genus.

[1] Anomaloglossus are characterized by cryptic dorsal coloration (brown or gray).

[1] Many species show large intraspecific morphological variability and lack of morphological characters that would allow easy species identification.
