Description. Field Characters. Adult female cover white, oyster-shell shaped; shed skins marginal, yellow to brown. Male not examined by author.

Slide-mounted Characters. Adult female with 2 or 3 pairs of well developed lobes, third lobes reduced or represented by series of low points.

Gland spine formula usually 1–2–2, with about 18 gland spines near each body margin from segments 5 to 7. Macroducts on pygidium about same size without duct between medial lobes, with 14–18 macroducts on each side of body on segments 5 to 7; submedial ducts on segments 2 to 4, with 39 to 41 ducts each; submarginal ducts on segments 2 to 4, with 38 to 40 ducts each. Perivulvar pores in 5 groups, about 53 pores. Perispiracular pores usually with 3 loculi, anterior spiracles each with 4–11 pores, posterior spiracles each with 1–5 pores.
