Remarks

• Systematics: Slide-mounted adult female with: enlarged setae conical, sides slightly concave, apices acute or slightly rounded, marginal setae slightly larger than other dorsal setae, large setae along body margin, setae abundant over surface; anal lobes heavily sclerotized with teeth on mesal margin; microtubular ducts moderate in length, 2 sclerotized areas, orifice bifurcate (Paik, 1978; Miller, personal observation, 1999).
• Structure: Female sac is strongly convex. Its color is a white to gray. Adult female reddish brown and turns red when boiled in KOH (Kuwana, 1902).
• Biology: Bisexual reproduction with a Lecanoid heterochromatinization in male embryos. Eggs are laid in dense wax ovisac at the stage of anatrepsis, i.e. incomplete ovoviviparity is characteristic of the species. Female reproductive system consists of a spermatheca attached at the junction of the oviducts and accessory glands attached at the base of a common oviduct (Gavrilov-Zimin, 2020
