( Figs. 114–116 ) Description. Male. Body rather small for this genus. Vertex of head divided by conical tubercles ( Fig. 114 ). Legs elongate and slender; fore femur about 1.4 times longer than the pronotum, ventrally unarmed, internal knee lobe without a small spine, external genicular lobe with 1 elongate movable spur; fore tibiae beneath with 2 external spurs and 2 internal spurs. Mid femur with an elongate movable spur on the internal and external genicular lobe, ventrally unarmed; mid tibiae beneath with 1 external and 1 internal spur. Hind femur without spines ventrally; hind tibiae above at each side with 48–52 spines respectively, arranged in groups. Supra internal spur of hind tibiae distinctly exceeding ventral-apex of hind metatarsus. Hind metatarsus keeled ventrally. Male genitalia as Fig. 115 . Female. Apex of subgenital plate projecting ( Fig. 116 ). Ovipositor longer than half the length of hind femur. Coloration. Body yellowish brown, mottled with dark blotches.

(length in mm) Body ♂ 11.0, ♀ 8.0; pronotum ♂ 5.0, ♀ 5.0; fore femur ♂ 7.0, ♀ 6.0; hind femur ♂ 15.0, ♀ 14.5; ovipositor 11.0. Specimens studied. Holotype , 1♂ , Qiqi country, Gongshanxian , Yunnan , alt. 1900m , 2010-VI-28 ~ VII-3 , collected by Bi Wen-Xuan ; paratypes , 2♀♀ , same data as holotype. Distribution. China ( Yunnan ). Diagnosis. This species is rather similar to T . ( G .) dispar sp. nov. and T . ( G .) verus sp. nov. , it differs from the latter two species by the epiphallus of male genitalia that is provided with two long arms instead of nearly triangular and trapezoid, and by the apex of the female subgenital plate projecting instead of notched. Etymology. The specific epithet ‘ vicinia ’ is used to suggest similarity to T . ( G .) dispar .
