Remarks

• Systematics: Danzig and Gavrilov-Zimin, 2015, determined that there were no discrete differences between Trionymus parvaster and T. kobotokensis and consequently, synonymized these two species.
• Structure: Female body elongate oval, up to 3.5 mm long. Antennae 6-7 segmented. Lets and antennae n some females thickened; hind coxae with translucent pores. Anal apparatus complete. Both pairs of ostioles well developed. Circulus small, oval. Multilocular pores few, present around vulva only. (Danzig & Gavrilov-Zimin, 2015)
• Biology: Occurring on the roots and in the leaf axils of the host plant.
• General Remarks: Good description and illustration of the adult female given by Kanda (1959a). Good description of the adult female given by Kawai (1980) and by Tang (1992). Good description and illustration of the adult female of junior synonym, T. parvaster, given by Danzig (1971; 1980b) and Tang (1992).
