Remarks
- Systematics: This species has been mis-identified as Balanococcus banbusum by Kwon, Danzig & Park (2003a). Danzig & Gavrilov-Zimin (2015) reviewed the mixed type material of Balanocccus kwoni and determined that the females from Italy (holotype ad some paratypes) did not differ from the types of Trionymus hamberdi, whereas females from Korea were conspecific with Trionymus orientalis (Danzig & Ivanova, 1976) (= ).
- Structure: Female body elongate, up to 4 mm long, pink in life. Antennae 7-8 segmented. Legs thin; hind coxae with translucent pores. Anal apparatus complete. Both pairs of ostioles present. Circulus small, from oval to almost quadrate. (Danzig & Gavrilov-Zimin, 2015)
- Biology: Lives in leaf sheaths of grasses. Junior synonym, Balanococcus kwoni described as living exclusively on bamboo. (Williams and Malumphy, 2012)
- General Remarks: Good description and illustration of the adult female given by Ter-Grigorian (1973), Danzig (1985) (as T. subradicum Danzig) and by Danzig (1997a). Good description of the adult female given by Borchsenius (1949) and by Tang (1992). Good description and illustration of the adult female of junior synonym, Trionymus orestes, given by Williams (1962). Description and illustration of adult female of junior synonym, Balanococcus kwoni, by Pellizzari & Danzig (2007).
