Carapace transversely subovate, width 1.41 times length; dorsal surfaces smooth, covered with short pubescence on surface, with longer plumose setae on lateral and frontal margins, regions demarcated, Hshaped gastric and cardiac grooves deep, distinct, surface adjacent appears crenulated in adult; anterolateral margin strongly convex, lined with small granules, appears entire except for low granulated tooth at junction with posterolateral margin; posterolateral margins subparallel, margin and surface with small rounded granules, median part with patch of raised granules resembling low lobe ( Figs. 1 View FIGURE 1 A, B, 7A). Frontal margin deflexed downwards, barely visible from dorsal view; bilobed with distinct median cleft, margin of each lobe distinctly convex ( Figs. 1 View FIGURE 1 B, C, 7B).
