The genus is based on holotype MB.R.1290, a partial mandible with teeth (the symphyseal region, where the two lower jaws meet and fuse into one element). The top of the back of the symphysis is very concave.
This species is characterized by its holotype MB.R.1290, which includes a partial jawbone with teeth (specifically, the area where the lower jaws merge to form a single unit). The upper surface of the rear of this joint exhibits a notable depression.
