Diagnosis Small temnopleuroid echinoid with wheelshaped test, flattened above and below. Apical disc always much larger than the peristome and forming up to 82% of the test diameter in the largest (adult) specimens. The first 4-6 couples of pores adorally not well separated by a wall and confluent on the inner surface of the plates. Interambulacral plates wide and low adapically, becoming narrower and taller adorally, always with a single primary tubercle. Angular pits deep, with steep edges; they are lacking adapically. Small sutural pits occur at each triple junction, also in the ambulacra. Primary tubercles surrounded by a slightly depressed areole. Low horizontal ridges at the adapical edge of both ambulacral and interambulacral plates. All tubercles finely, but distinctly, crenulate. Auricles not joined above. Buccal notches almost absent. No morphological trace of dimorphism.
