Wyushinamia bifurcata Zhang and Duan sp. nov.

Figs. 9–16

Vertex light yellow with six small dark brown marks on anterior margin, and brown longitudinal band midway between midline and eye extending to posterior margin of pronotum; eyes dark, ocelli light yellow; clypeus with fuscous arcs. Pronotum light yellow with six brown longitudinal stripes including the two middle ones from vertex. Scutellum stramineous. Legs marked with brown. Forewings stramineous or brown, cells bordered with brown, veins paler.

Vertex convex, nearly as long as next to eye, ocellus separated from eye by less than ocellus’ diameter; apex of clypellus tapered. Pronotum nearly as long as vertex. Scutellum slightly shorter than vertex. Forewing macropterous, outer anteapical cell more than 1/2 central anteapical cell, central anteapical cell constricted, inner anteapical cell open basally, veins conspicuous, discal cell near costal area and with a cross vein.

Male genitalia: Pygofer constricted distally. Subgenital plate with lateral margin concave. Valve with anterior margin arched, posterior margin triangularly produced medially. Aedeagal shaft slender, longer than twice length of connective, apex bifurcate with a toothlike protrusion at inside of each branch, aedeagal shaft sinuate in lateral aspect, gonopore apical on ventral surface.

Measurement Male Length (including tegmen): 4.1mm.

Material examined

Holotype ♂, China: Fujian Prov., Mt. Wuyishan, Xianfengling , 21 July 2003, coll. Duan Yani ( NWAFU) . Paratypes: 2 ♂, 1 ♀, China, Fujian Prov., Mt. Wuyishan, Pikeng , 20 July 2006, coll. Yang Meixia.

Remarks

Externally this species resembles some species of Deltocephalus but differs in having more elongate male pygofer and subgenital plates, and the aedeagal shaft apex bifurcate with a toothlike protuberance at inside of each branch.

Etymology The species name is based on the apically bifurcate aedeagal shaft.
