(Figs 28–35, 50–51)

Type material. Holotype: 1♂, P. R. China, Mt. Gaoligong, Yunnan Province, 6 August 2013, coll. Zhihua Fan; paratypes: 3♀, same data as holotype (all IEGU).

Length: ♂ 4.68mm, ♀3.94–4.70mm

Crown yellowish orange, female with black patch posteriorly between eyes (Fig. 50). Eyes black (Fig. 50). Face yellowish, anteclypeus black apically (Fig. 51). Pronotum orange, with blackish posteromedial patch (Fig. 50). Scutellum yellowish, apex slightly black, scutoscutellar sulcus brownish (Fig. 50). Forewing brown, hind wing hyaline (Fig. 50). Legs yellowish (Fig. 51).

Male ventral abdominal apodemes reaching middle of segment 4 (Fig. 28). Male pygofer strongly narrowed anteriorly, anterior margin unsmooth, dorsal margin pigmented (Fig. 30). Subgenital plates extended beyond pygofer in lateral view, completely fused with only slight median emargination distally, bearing 8 macrosetae in one row and ca. 50 microsetae in 3 or 4 rows (Fig. 29). Paramere elongate, apex strongly bent, with thin preapical process extended basad, apophysis attenuated preapically (Fig. 31). Aedeagal shaft short, broad, ovoid, strongly compressed, basal process nearly symmetrical with three pairs of branches, middle branches extended dorsad and crossing basal branches in lateral view, middle length expanded in lateral view (Figs 32, 33). Anal tube process curved in lateral view (Fig. 35). Connective with paired apical and basal lobes, apex broader than base, apical margin concave (Fig. 34).

Etymology. The name of the new species refers to the medially inflated basal aedeagal process.

Remarks. The new species differs distinctly from others in the genus in the shape of the paramere apex (Fig. 31) and aedeagal process with three pairs of branches (Figs 32, 33).
