Asymmetrasca hypercurvata, Liu and Zhang, sp. nov.

(Figs 30–37, 98–100)

Type specimens. China: holotype ♂, Fujian Prov.: Huanggang, Mt. Wuyi, 16.viii. 2008, 780 m, coll. Xia Gao & Xiaoting Li; paratypes: 1♂, same data as holotype; 2♂♂, Zhejiang Prov.: Qingliangfeng, Lin’an, 6.viii.2008, 1100 m, coll. Daozheng Qin. All in NWAFU.

Length: ♂ 3.0 mm–3.1 mm.

General color of body yellow-greenish (Fig. 100). Crown yellowish, with dark green markings on each side of coronal suture obvious (Fig. 98). Eyes black. Pronotum broad, with irregular patches of cream-yellowish on anterior margin. Lateral parts of scutellum with cream-yellowish triangular spots. Forewing and hind wing semitransparent. Abdomen yellow. Legs pale yellow to pale green (Fig. 99).

Ventral abdominal apodemes subparallel-sided, reaching midlength of segment 5 (Fig. 32). Male pygofer in lateral view slightly narrowing caudad, ornamented with 7–9 stout setae on each side of pygofer lobe (Fig. 30); pygofer appendage slightly arched dorsocaudad, not exceeding caudal margin of lobe in lateral view. Anal tube process well developed, rugose apically (Fig. 31). Subgenital plate in lateral view curved gradually caudodorsad apically, tapering to rounded apex; with numerous macrosetae and fine setae somewhat irregularly scattered; setae group A with 3 stout setae, group B with 16–22 short microsetae, group C with three rows of macrosetae, group D arranged in single row through most of length, irregular at base and apex (Fig. 37). Paramere long, subapically curved, dentifer with 5 teeth, 4–6 setae present subapically (Fig. 36). Connective broad, with posterior margin deeply emarginate medially (Fig. 35). Aedeagus with preatrium long, straight; dorsal apodeme obsolete; shaft irregularly sinuate and slender, slightly tapered, without dorsal denticuli; apical process long, slightly curved, apex expanded and distinctly bifid (Figs 33–34).

Etymology. The specific epithet was formed by combining the Greek prefix " hyper -" meaning "above" with the Latin " curvus ", meaning curve and refers to the overlap of the aedeagal appendage with the shaft in lateral view.

Diagnosis. This species is similar to A. decedens Paoli, 1932, but differs from the latter in having the aedeagus with a longer process that overlaps the shaft in lateral view and has the apex bifid.
