Gavrilov-Zimin.  New data. 2n = 16; 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 (Fig. 2).  Comments. Only two species of the large genus  AcanthococcusSignoret, 1875 have been previously studied cytogenetically, i.e. European  A. agropyri(Borchsenius, 1949) and  A. insignis(Newstead, 1891), both with 2n = 16 ( Gavrilov 2004, 2007). [Nota bene! The studied specimens differ from a common  Acanthococcus onukii(=  Anophococcus onukii) in the conical setae with blunt apices. The generic name  AnophococcusBalachowsky, 1954 is considered here as a synonym of  Acanthococcus(synonymized by Danzig 1980: 205)].
