Superomarginal figs granulose (Fig. 5g). Two fringes of marginal spines aligned horizontally. First row of spines of inferomarginal figs with three marginal spines, disposed in parallel to each other, two being of the same length and one shorter. Second row with four elongate and slightly flattened spines, three of which are subequal in length and one much shorter. Oral spines short, forming a bundle at the apex of the jaw (Fig. 5f).
