Porównanie

Differs from other species of Buvignieria in having the widest teleoconch and a spiral keel at the abapical portion of the whorl. The pattern of ornamention of protoconch 2 is similar to that of  an B. piserai and the paratype of B. calloviana. The pattern of protoconch 1 and 2 ornamentation is similar to that of many Recent and Tertiary Alvaniinae
