DESCRIPTION

Cortical shell includes Pseudoaulophacid structure composed of meshwork of equilateral, triangular pore frames with rounded nodes at vertices. Four spines about similar in length, wide at the base and tapering distally, with sharp ends. Spines coplanar and tetracarinate with very wide grooves adjacent to very narrow ridges.

REMARKS

This genus differs from Udalia (in Carter et al. 1998: 59) by having tetracarinate instead of tricarinate spines.
