Medium-sized, roughly roundish pentagonal in ventral view. Epitheca dome-shaped; hypotheca asymmetrically bipedal, the left lobe being the largest. Cingulum deeply impressed, subcentral, descending, displaced distally about one girdle width, without lists. The cingulum has eleven sub-equal rec- tangular plates plus a transitional plate at the right end. Sulcus narrow, only slightly excavated, with six plates. Theca easily exuviated. Cell length 53-56 ^,.
