Remarks
- Systematics: This species possesses rather unusual features for Trionymus in its extenal appearance, and this was the reason for placing it in Dysmicoccus. In the genus Trionymus, this species name is a major homonym of Trionymus mongolicus Danzig, 1980, which was replaced in Danzig & Gavrilov-Zimin, 2015, with a new name - Trionymus kerzhneri.
- Structure: Female body broadly oval, strongly convex, up to 4 mm long. Antennae 6-setmented. Legs well developed; hind coxae with translucent pores; claw digitules shortened with pointed apex. Anal apparatus complete. Both pairs of ostioles well developed. Circulus small, oval. Multilocular pores forming transverse rows on abdominal sternites. Trilocular pores numerous, evenly scattered on the entire body surface. (Danzig & Gavrilov-Zimin, 2015)
- General Remarks: Good description and illustration of the adult female given by Danzig (1969) and by Tang & Li (1988). Good description of the adult female Tang (1992).
