Intasuchus is an extinct genus of temnospondyl amphibian from the Middle Permian of Russia.

Intasuchus most likely belongs to the group Archegosauroidea, Permian relatives of the large, mostly Mesozoic temnospondyl clade Stereospondyli.

Prominent ridges run along the skull surface from the eye sockets to the nostril openings.

[1] The phylogenetic analysis of Schoch and Milner (2000) placed Intasuchus as a basal member of a group called Archegosauriformes.

Below is a cladogram from that analysis:[2][3] Sclerocephalus haeuseri Cheliderpeton vrayni Cheliderpeton latirostre Intasuchus silvicola Archegosaurus dyscriton Archegosaurus decheni Collidosuchus tchudinovi Platyoposaurus stuckenbergi Australerpeton cosgriffi Melosaurus uralensis Konzhukovia vetusta
