Sixth somite broader than fifth, proximal margin slightly convex medially, anterolateral margin gently convex, anterior (distal) margin weakly concave. Telson transversely subtriangular. Anterior border of abdominal cavity densely covered with soft setae. Vulva (Fig. 6E, F) on sixth thoracic sternite subcircular in outline, with conspicuous subconical operculum directed mesially, basally demarcated by broad chitinous suture.
