Within the Nycteroleteridae, it is considered most closely related to Emeroleter. However, its legs were shorter than those of Emeroleter and its skull was flatter.{{Cite web|url=http://palaeos.com/vertebrates/anapsida/nycteroleteridae.html|title=Palaeos Vertebrates Anapsida: Nycteroleteridae|website=palaeos.com|access-date=2018-02-16}} Nycteroleter was insectivorous, and may have been nocturnal. It was a small animal, less than a metre long.
