Diagnosis Test is dome-shaped, 16 to 20 mm in diameter and nearly 11 to 11.5 mm in height, flattened below and subconical adapicaly. Nine or ten primary tubercles in each interambulacrum column, arranged in regular series throughout. The peristome is very large and circular in outline, approximately 63-72.5 % of the test diameter, and has moderately sharp notches. The greatest ambulacrum width is 20% of the test diameter. Ambulacral plates are compound, trigeminate adapically and adorally, but quadrigeminate at the ambitus. Pore pairs are uniserial and two pores are separated from each other by a raised interporal knob. The periperoct is triangular in shape and is 2 to 2.7 mm in diameter, corresponding to 12.5- 14.5% of the test diameter. Apical disc dicyclic, thick and forming a raised platform. The genital plates pentagonal, together form a five-pointed star, and the gonopores are at the outer points. Three of the genital plates are represented as having a tubercle on the inner edge adjacent to the periproct. Ocular plates are smaller and projecting. Tubercles imperforate and non-crenulate. Interambulacral plates a little wider than tall, with a large primary tubercle on each. Peristome is rounded in outline and very slightly sunken. [details]
