Setae av, and pVi of tarsus 11 normal, not stout and clawlike; setae av, of tarsus IV acutely spinifonn; some ventral setae of femur IV, genu IV, tibia IV, and tarsus IV enlarged somewhat but not spiniform; usual leg setae present and normal. Venter. Anterior margin- of sternal shield slightly convex; posterior margin extremely con- cave (invaginated to level of first pair of pores); anterolateral and posterolateral projections long and narrow; setae st. 2 slightly closer to st. 3 than to St. 1. Genital shield slightly expanded posterior to genital setae and rounded pos- teriorly; line formed by end of genital flap ribs slightly arched; setae Jvl on soft integument but often touching margin of genital shield. Anal shield pyrifomi with paranal setae at level of middle of anal field. Soft integument of venter bears 20 to 22 pairs of medium-sized (length 15-17 /an) opisthogastric setae. Peritreme of unifonn width except slightK' wider posteriorly; extends to level of middle of coxa 1 or slightly beyond. Dorsum. Greatest width of dorsal shield at level of setae Zl or SI; lateral sides straight to slightly concave and gradually converging an-.
