Description
Original diagnosis after Sambou, Hautier, Sarr, Tabuce, Lihoreau, Thiam, Lebrun, Martin, Cappetta & Adnet, 2020 [28632]: The new species distinguishes from the unique typespecies of genus by having teeth with higher transversal keel thatlooks as more protruding, undulated and often marked by three rounded pseudo cusplets in lingual view. Two of these cusplets arelocated at the margin while the third one, the highest, is situated inthe cusp axis. Compared to the type species, ornamentation of theenameloid of the lingual and labial faces is more finely developed,especially under the transversal keel with an alveolar networkshape.
