Description

Shell small, similar to antipodum (Filhol), but differing in general outline and strength of concentric sculpture. Both anteriorly and posteriorly the dorsal margins slope downwards much more rapidly. In antipodum the posterior dorsal margin is much higher and inflated. The different dorsal outline gives triangulare a much more triangular shape. Sculpture of widely spaced concentric grooves, much coarser and less numerous than in antipodum. Hinge essentially similar to antipodum. In the right valve there is a large triangular cardinal anteriorly situated, with a long hooked, narrow lamella above and two narrow, divergent lamellae posteriorly, the inner much stronger. The left valve has a hooked cardinal anteriorly and an elongated posterior lamella. Length, 2,6 mm.; height, 2,3 mm.
