Staurois parvus is a small representative of the genus. Previously this taxon has been included in S. tuberilinguis, but Matsui (2007) has argued that it is a species of its own, but related to S. tuberilinguis (recently confirmed by Arifin et al. 2011). The hallmarks of S. parvus are the short snout (compare to eye-diameter) and the small body size (males ca. 20–24 mm SVL, females 26–31 mm).

S. parvus has been reported from Brunei and adjacent Sarawak, as well as Sabah. As the other species in the genus, it uses foot-flagging for intraspecific communication.

Details of the reproductive behavior are only known from captive breeding. The tadpoles are similar to those of S. guttatus.
