Legs elongate and slender; fore femora about 1.4 times as long as the pronotum, beneath unarmed, internal knee lobe with a small spine, genicular lobe with 1 elongate movable spur; fore tibiae beneath with 2 external and 2 internal spurs. Mid femora with an elongate movable spur on the internal and genicular lobe, beneath unarmed; mid tibiae beneath with 2 external and 1 internal spur(s). Hind femora beneath with 2 inter spines and without outer spines; hind tibiae above with 64–69 outer and inter spines respectively, arrange in groups, inner subapical spur of hind tibiae slightly longer than hind metatarsus. Hind metatarsus keeled beneath and with an apical spine above. Male epiproct shorter than paraproct ( Fig. 18 View FIGURES 18 – 20 ). Dorsolateral lobes of male genitalia sclerotized and epiphallus trapezoidal ( Fig. 19 View FIGURES 18 – 20 ).

Diagnosis. This species is closely related to Pseudotachycines ovalilobatus (Gorochov, 2010)   comb. nov., but differences from the latter in that: hind tibiae armed with 64–69 spines each side above and subgenital plate of female subquadrate.
