DESCRIPTION

Shell small, rusty red, H to 16.6 mm, L to 18.0 mm, thin shelled, subovate, longer than high H/L 0.90, posterior margin quadrate, slightly inflated (T/L 0.28). Umbones low, slightly posterior of centre. Sculpture of numerous (c. 60), closely spaced, fine, rounded, radial ribs, that occasionally divide. Ribs crossed by low, fine, irregular, commarginal threads. Ribs obsolete on anterior and posterior dorsal areas. Posterior sulcus marked by lack of ribs. Lunule lanceolate, slightly asymmetric, RV extends into LV. Hinge plate narrow, RV with single, small cardinal tooth, a single small, elongate anterior lateral, and a small posterior lateral fold. LV with two very small cardinal teeth, anterior cardinal twice size of posterior cardinal, anterior lateral indistinct, posterior lateral absent. Ligament short, inset. Anterior adductor scar medium length, detached for 1/3 of length. Posterior scar ovate. Pallial line wide, continuous. Shell inside pallial line dull with radial striations; outside pallial line, glossy, shell margin crenulate, with ribs extending deeply into shell interior. Internal coloration rusty red.
