In anterior view, carapace rounded triangular (Fig. 2K). Left valve slightly overlapping right valve along anterior and posterior margins. Anterior and posterior margin rounded in lateral view. Marginal infold broad along anterior margin and narrow in posterior area (Fig. 2C, D). Anterior vestibulum occupying most of area in marginal infold, containing five and six marginal pore canals in left and right valve, respectively (Fig. 3). In both valves a thick, irregular ridge runs diagonally upward across the anterior infold, and three short buttress-like ridges or wrinkles run anteriorly from the upper part of this ridge for additional strength. Adductor muscle scar pattern consisting of row of four elongate closely spaced scars and three frontal scars (Figs 2O; 3). Carapace surface with faint granular texture visible at high magnification, resulting from close-packed, tiny tubercules (Fig. 4A). Sieve type normal pores with recessed sieve plates and thick rims on carapace surface (Fig. 4). Pore systems with one bristle. Hingement adont type (Fig. 2M, N). Color translucent white; living individuals have brown granular patterns.
