Diagnoza Protoconch ornamented with adapical spiral row of tubercles and axial, very weakly prosocline (almost orthocline) riblets, extending from upper periphery to abapical suture. Distance between row of tubercles and axial riblets of protoconch short. Teleoconch starting with strong opisthocline axial ribs and pustules arranged into spiral threads. On the later teleoconch whorls, axial ribs vanishing and pustules becoming randomly distributed. Porównanie The protoconch is similar to T. calloviana but the teleoconch differs significantly in the continuous reduction of the axial ribs and the arrangement of the pustules.
