Description edit
This animal is mostly known from fossilized molars. Those were low-crowned (brachydont) and bunolophodont. The upper molars had a highly developed crochet unlike other genera of Henricosborniidae. The third molar either doesn't have a metastyle or it is weakly developed. For the lower molars, the hypoconulid is less separated from the hypoconid. The entoconid of the third molar was highly developed as an independent cuspid.[2]
