Staurois tuberilinguis (from Greek stauros = pole, cross, Latin tuber = bulb, and Latin lingua = tongue) is a species of the genus Staurois from the family of real frogs . In English it is called Green-spotted rock frog , i.e. green -spotted stone frog .
For a long time Staurois parvus and Staurois tuberilinguis were considered one species. It was not until 2007 that Starois parvus was spun off from Staurois tuberilinguis because the two species differ mainly in size but also phylogenetically.
features
It is smaller than Staurois natator and its skin is rougher. He also has rows of warts on his back . The body length is up to 25 mm in males and 35 mm in females. According to Matsui, males have a head-to-trunk length of 27 to 31 and females between 33 and 38 mm. They have a slender head with a pointed snout . The fourth finger is remarkably short, which distinguishes it from other Staurois species. The ploughshare does not have teeth. Papillae of the tongue are present. The eggs are colorless.
distribution
The species is endemic to Borneo . So far it has been found at altitudes of 150 to 1800 meters, but very rarely below 500. Larger numbers are often found in rocky streams. According to the Red List, the species is close to being endangered (NT, Near Threatened). It is relatively widespread, but its occurrence is tied to undisturbed forests along large rivers. Their entire range is therefore estimated to be no more than 2000 km². The size and quality of their habitat will presumably decrease due to the deforestation of the rainforest.
Habitat
Staurois tuberilinguis lives in both flat and mountainous rainforests and inland wetlands . Mostly on the banks of clear, fast flowing, rocky streams . Like other Staurois species, they often sit on rocks and stones, preferably in rapids. The eggs are also deposited in fast-flowing waters. It was also found in piles of leaves at quiet stream spots.
