The indentation of the narrowing between the half- cells is semicircular, quite wide, obtuse, and U-shaped in the inner part.semi-cell with a strongly convex top equipped with 6 two-spiny interconnected papillae on the sides and 1 papilla on each side lying at the base of the outstretched arm, with 2 short spines. The indentation of the narrowing between the half- cells is semicircular, with almost parallel sides in the inner part, U-shaped. The lateral edges of each arm with additional paired spines and one pair lying at the base of the arm. The ends of the arms have two spikes.half-cells with a moderately convex top, triangular in outline, with a slight concave in the middle of the side, indentations between the top, the lateral and top surfaces of the half-cells, with 6 two spiny papillae not connected in a circular wreath. Opposite each side of the half- cell there are two bispinous papillae. The arms are weakly extended with 3 pairs of short spines, two of which are located laterally, 1 pair under the top of the semi-cell arm. The ends of the arms are rounded with two spikes.OccurrenceWestern Europe, and New Zealand. Sri LancaOnly in UkraineOnly in Ukraine
