Description:
Valve linear, strongly gibbous in the middle portion; poles slightly swollen and rounded. Axial area small and linear. Central area wide, generally rounded, and often with a thickening of the valve beneath the central area (see Round et al., 1990 for SEM illustrations of this feature).
