Apical spine usually protrudes from shell surface as a short thorn.QTLattice shell moderately robust, with subcircular pores, and com-monly with few scattered thorns on the surface. Open base of inverted-conical thorax has no differentiated peristome except a less porous area terminated usually by an irregular number of short triangular teeth.
