Figs 16 , 20 m–p

Description. Ground color infuscated, face brown, eyes black, basal triangular on mesonotum dark. Head as wide as pronotum, crown fore margin rounded apically, anteclypeus broad.

Male abdominal apodemes 2S nearly reached hind margin of sternite IV. Anal tube appendage clamp-shaped, caudal branch longer than cephalic branch.

Pygofer lobe with ventral appendage C-shaped from lateral view, upper branch long, curved ventrad, lower branch short and straight, pointed apically. Subgenital plate with small apical process, with about 4 macrosetae in oblique row near lateral margin, row of marginal setae from middle part to apex. Style with apex curved inward sharply, preapical lobe indistinct. Connective long, margin of central lobe straight. Aedeagal shaft straight, directed dorso-caudad, slim in lateral view and thick in caudal view, atrium large.

Measurement. Male length 3.50–3.60 mm.

Material examined. Holotype: ♂, CHINA, Zhejiang Prov., Mt. Wuyan, 07 viii 2007, coll. Xinmin Zhang. Paratypes: 1♂, same data as holotype; 1♂, CHINA, Hunan Prov., Mt. Heng , 11 viii 1985, coll. Yalin Zhang & Yonghui Chai. [ NWAFU].

Etymology. The new specific epithet is derived from Latin noun “ forcipis ” which means pincer, referring to the clamp-shaped anal tube appendage.

Diagnosis. The new species can be distinguished from the type species by the bifurcated anal tube appendage, the C-shaped pygofer ventral appendage and the much longer connective.
