Remarks
- Systematics: Subfamily: Pseudococcinae (Choi & Lee, 2022) Williams (2004a) considered the genus Kermicus to be closely related to genus Chaetococcus Maskell, 1898. Based on the morphologies of the adult female and first-instar nymph describedin the literature, Wu, et al., 2020 suggest that the genera Idiococcus Takahashi & Kanda and Porisaccus Hendricks & Kosztarab are more closely related to Kermicus than is Chaetococcus, since I. maanshanensis, P. jiuhuaensis and K. wroughtoni share with the following features: (1) adult female lacking tubular ducts and possessing a bag-like or sac structure densely covered with duct-like pores in the position of each hind leg; (2) first-instar nymphs all having the same trilocular pore structure (Tang, 1984; Hendricks and Kosztarab, 1999; Wu, 2005). In contrast, the adult female of Ch. bambusae has a plate-like structure in the position of each hind leg instead of a bag-like structure, and the first-instar nymph has a different trilocular pore structure from that found in K. wroughtoni (Yang & Kosztarab,
1967).
- Structure: Body of adult female rotund, hemispherical, becoming heavily sclerotized with maturity. Anal lobes absent. Antennae plate-like. Eyes absent. Clypeolabral shield of mouthparts with long internal anterior extension. Legs absent; positions of hind legs each indicated by sac-like area containing numerous duct-like pores. (Wu, et al., 2020)
- General Remarks: Definition and characters by Newstead (1897), Tang (1992), Hendricks & Kosztarab (1999) and by Williams (2004a).
