Anomaloglossus
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.[2][4] It used to be placed in the family Dendrobatidae (together with other genera in the current Aromobatidae[1][5]), and is still placed in that family by some sources.[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). Dorsal skin is posteriorly granular. The toes are webbed, ranging from basal to extensive. The fingers have weakly expanded discs.[1] Many species show large intraspecific morphological variability and lack of morphological characters that would allow easy species identification.[4]
