Acanthococcus prope onukii (Kuwana, 1902)  Figs 1eView Figure 1, 2View Figure 2

Material.

K 1513, Thailand, Chiang Mai, slope of Doi Suthep Mt. near the University, on leaves of bamboo, 8.XI.2019, I.A. 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. 2View Figure 2).

Comments.

Only two species of the large genus Acanthococcus  Signoret, 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 Anophococcus  Balachowsky, 1954 is considered here as a synonym of Acanthococcus  (synonymized by Danzig 1980: 205)].
