Systematics: This species is closely related in morphology to Trionymus vaginatus Matesova known only from the description and from the type series collected in Eastern Kazakhstan from the leaf axils of perennial herbs of the family Asteraceae.. Trionymus sengirkumensis differs by having only 2 (instead of 4 or 5) pairs of true cerarii, in a small, weakly sclerotized, or absolutely not developed plate of the last pair of cerarii, and in the presence of dorsal multilocular pores on the posterior abdominal segments. These dorsal pores are singular in the specimens from the series of the holotype but form transverse rows on several posterior abdominal tergites in the series of the paratypes.
Structure: Body oblong-oval, about 3 mm long, rose-red in living individuals. Antennae 7- or 8-seg mented. Legs normally developed, without translucent pores; claw without denticle; claw digitules with clavate apices.
General Remarks: Detailed description and illustration in Gavrilov-Zimin & Kurochkin, 2019a.
