Deltocephalus uncinatus sp. nov.

( Fig. 4 ; Plate I: E; Plate V: C; Plate VI: C)

Length. Male: 3.3–3.5mm; female: 3.6–4.0mm.

Ochraceous. Vertex with sinuate dark brown band on antero-lateral margin and orange or brown longitudinal band each side of midline extending to scutellum ( Fig. 4 A; Plate I: E); frontoclypeus with fuscous arcs. Pronotum stramineous with two orange or brown longitudinal bands on each side in addition to those continuing from vertex; scutellum stramineous ( Fig. 4 A; Plate I: E). Leg marked with brown. Forewing with cells embrowned, veins paler (Plate I: E).

Forewing macropterous, inner anteapical cell open basally. Sternal apodemes at base of abdomen long with rounded apices ( Fig. 4D ).

Male genitalia. Subgenital plate broadly triangular ( Fig. 4 C); style preapical lobe short, apophysis digitate, slightly laterally curved ( Fig. 4 E); aedeagal shaft short and robust, distinctly broad basally, strongly curved dorsally at apical 0.33, apex directed cephalad and strongly notched ( Figs 4 G, 4H).

Female genitalia. Hind margin of seventh sternum as in Plate V: C and Plate VI: C.

Material examined. Holotype: ɗ, China, Zhejiang Prov., Wuyanling, 680m, 30 July 2005, coll. Duan Yani. Paratypes: China, Zhejiang Prov.: 1ɗ, 1Ψ, Mt. Gutianshan, 17, 18 August 2003, coll. Dai Wu; 3ΨΨ, Wuyanling, 400m, 1 August 2005, coll. Duan Yani, at light; 1Ψ, Wuyanling, 1000m, 1 August 2005, coll. Duan Yani; Hunan Prov.: 1Ψ, Zhangjiajie, 25 July 2002, coll. Sun Qinxia; Guangxi Prov.: 1Ψ, Fangcheng, Naliang, 9 December 2001, coll. He Zhiqiang; Hainan Prov.: 1Ψ, Liangyuan, 30 May 1983, coll. Zhang Yalin; 1Ψ, Mt. Diaoluoshan, 4 June 1983, coll. Zhang Yalin, at light; 1Ψ, Country Baisha, Yinggeling, 23 May 2007, coll. Duan Yani. All NWAFU.

Remarks. This species is closely related to vulgaris , but differs in the broadly triangular subgenital plate ( Fig. 4 C) and in having the apex of the aedeagus directed cephalad ( Figs 4 G, 4H).

Etymology. This name is based on the hooked apex of the aedeagus.
