Diagnosis
ReferenceDiagnosis
S. F. Mitchell 2013A genus of Youngicaprininae with a straight to arcuate curved to spiral-shaped Right Valve and a gentle prosogyrally coiled left valve; the ligament is internal and crescent-shaped in the right valve, and represented by a pit in the left valve; there is no external ligamental groove. The right valve inner shell, including the central tooth,is filled with pallial canals, except the sockets for the teeth and the body cavity which are filled with tabulae. The anterior tooth is larger than the posterior tooth, both teeth are solid, or contain a few rudimentary irregular pallial canals in the Left Valve. The posterior myophore of the left valve is tooth-like and solid; it fits into a socket in the right valve. The anterior myophore of the left valve is composed of four to ten compact ribs separated by furrows filled with lines of pallial canals; it fits into a cavity and embayment in the right valve.
