Remarks

• Systematics: Danzig & Gavrilov-Zimin (2015) transferred Neotrionymus borchsenii to Trionymus because it has "numerous trilocular pores on both body sides and small number of dorsal multilocular pores" and "a tendency to irregular distributin of triloculars on body surface."
• Structure: Adult female body oval, up to 3 mm long. Antennae 7-segmented. Hind coxae enlarged, with numerous microtubular ducts which are also present on the metathorax near hind coxae. Anal apparatus simplified, with reduced number of pores and spinulae and 6 setae, similar in length to diameter of anal ring. (Danzig & Gavrilov-Zimin, 2015)
