Original description: The skeleton is composed of two segments. Internai skeletal structure consists of MB,A,D,L and AL. The junction of A and AL is on the shell. Connecting arches in this genus comprise only AL, without VL or LL. The first segment is distinguished from the second segment at the apical to lateral side by the furrows along AL, but at the ventral side the boundary between the two segments is not recognizable because VL and LL are absent. The first segment is hemispherical with a short apical rib. The second segment is widely expanded bell-shaped with three distinct dorsal and lateral ribs extending to distal feet. Remarks.—This genus is distinguished from Pseudodictyophimus, Ceratocyrtis and Lophophaena by the absence of V, VL and LL.
