Staurois tuberilinguis

Staurois tuberilinguis is a species in the true frog family (Ranidae). It is wwidespread on Borneo.

Its snout-vent length is 27–31 mm in males and 33–38 mm in females. It has a markedly slender head with a pointed snout and a rather short fourth finger, distinguishing it from its relatives. Its vomer lacks teeth, and it has a lingual papilla. The eggs are unpigmented.

Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and rivers. It is becoming rare due to habitat loss.

A smaller relative, only known from the Crocker Range in Sabah (Malaysia), was described as Staurois parvus. Later, it was considered a junior synonym of S. tuberilinguis, but more recently it was confirmed to be distinct according to morphological and DNA sequence data.
