Description. Male. Body rather large. Vertex of head divided into conical tubercles. Legs elongate and slender; fore femora about 1.5–1.6 times as long as the pronotum, beneath unarmed, internal genicular lobe with a small spine, external genicular lobe with 1 elongate movable spur; fore tibiae ventrally with 2 external and 1 internal spur(s). Mid femora with an elongate movable spur on the internal and genicular lobe, ventrally unarmed; mid tibiae ventrally with 1 external spur and 1 internal spur. Hind femora ventrally with 2–4 inter spines and without outer spines; hind tibiae above with 49–56 outer and inner spines respectively, arranged in groups. Super internal spur of hind tibia exceeding the dorso-apical spine of metatarsus ( Fig. 20 ). Hind metatarsus keeled ventrally. Epiphallus of male genitalia like a hat, median lobe of male genitalia with some small spines and with a rather large triangular spine ( Fig. 21 ).

Female. Subgenital plate with hind margin slightly concave and with spine-like projection at apex ( Fig. 22 ). Ovipositor shorter than the half of hind femora.

(T.) baiyunjianensis sp. nov., but differs from the latter in that: body size rather large (18.0–23.0 mm); epiphallus of male genitalia like a hat, median lobe of male genitalia with some small spines and with a rather large triangular spine in the middle part ( Fig. 21 ); female subgenital plate with hind margin slightly concave and apically projected ( Fig. 22 ).
