Description
Original diagnosis after Kirkland, Eaton & Brinkman, 2013 [20268]: Species of Pseudomyledaphus in which vertical sides of crown form sharp angle with both top and base of crown (Figs. 9.17, 9.18); oral surface of crown including transverse crest weakly developed. The oral surfaces of crowns are invariably deeply worn. Symphysial teeth highly distinctive with subcubic crowns overlying significantly more slender roots.
