Dorsal surface unarmed and barely setose, moderately convex from side to side, slightly convex on gastric region, without depression. Lateral margins divergent posteriorly to point one-third from posterior end, with 6 spines; first anterolateral, moderately large, directed anteriorly, terminating in tip of lateral orbital spine, second to sixth smaller, nearly equidistant from one another, second somewhat posterior to midpoint between, and, somewhat dorsal to level of, first and third, last spine situated at proximal third of lateral margin. Rostrum directed slightly ventrally, broad triangular (1.2–[1.4] × broader than long), with interior angle of 36–[40]°, ending in sharp tip; dorsal surface concave; lateral margin smooth and slightly concave; length 0.4 × that of remaining carapace, breadth 0.7–[0.8] × length of posterior carapace margin. Lateral orbital spine subequal to, situated at same level as, anterolateral spine of carapace, directed anterolaterally. Pterygostomian flap anteriorly angular, produced to distinct spine, smooth on surface, posterior portion half as high as anterior portion, when measured between linea anomurica and ridge along ventral margin.
