Type: Smilerpeton aciedentatum Dawson.

The type species was originally referred to Hylonomus, but further study induced Dawson to refer it to a new genus. Dawson gives ([216]) the following characteristics of the genus:

"Form somewhat elongated, and limbs short. Mandibular and maxillary teeth wedge-shaped, with cutting edges. Palatal teeth numerous, some of them large. Abdominal scales oval. A single species is known, S. aciedentatum, from the Coal Measures at the South Joggins, Nova Scotia."
