Holotype ZPAL Ga.9/59 from the Valanginian (Early Cretaceous) of Wąwał in lateral and apical view; black arrow indicate demarcation between protoconch 1 andprotoconch 2.

Diagnoza

Conical teleoconch ornamented with broad axial ribs (about 17–18 per whorl) and one spiral keel situated on abapical part of whorl. Whorls strongly angulated. Base demarcated by angulation of whorl. Surface of teleoconch covered by fine, densely packed lirae. Protoconch 2 ornamented by oblique or spiral threads. Protoconch 1 ornamented by 6–7 spiral threads.

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
