Leofa (Prasutagus) forcipatus Duan and Zhang sp. nov.

Figs 3A–H

Length. Male: 3.0– 3.1mm; Female: 4.1–4.3mm.

General coloration ochraceous. Vertex, with many brown spots.

Male genitalia. Pygofer with dorsal margin abruptly tapered caudally adjacent to base of anal tube, posterior margin bifurcate with small digitate upper branch; dorsal inner appendage very large, wrench-shaped with caudal margin of lower branch serrate. Style in dorsal view with apical apophysis curved laterally and tapered to acute apex, slightly expanded basally, lateral lobe well developed. Connective Y-shaped with stem short. Aedeagal shaft broad in lateral view, compressed with apex fan-shaped; with flange-like processes on each side subbasally. Processes between connective and aedeagus long, extending to near level of apex of aedeagus in lateral view.

Female genitalia. Hind margin of seventh sternite concave, with a median W-shaped lobe, median region dark pigmented.

Types. Holotype: ď, China, Yunnan Prov., Yongren, 1981-III-23, coll. Zhou Yao, Liu Mingtang & Zhou Jingruo (NWAFU). Paratypes: China, Yunnan Prov., 1Ψ, China, Yongren, 1981-III-21, coll. Zhou Yao, Liu Mingtang & Zhou Jingruo; 1ď, 1Ψ, County Yuanmou, Womaoxiang, Dashao Forestry Station, 2005-XI-27, coll. Li Qiao, Host: Dodonaea (NWAFU).

Remark. This species can be distinguished by the bifurcate apex of its pygofer, very large wrench-like inner appendage of the pygofer lobe and broad aedeagus in lateral view with a flange-like appendage on each side of the shaft subbasally against the ventral surface.

Etymology. The species takes its name from the Latin forceps for the pincer-like inner appendage of the pygofer.
