Cofana nii Yang, Meng & Li , sp. nov.

( Figs 7 , 25–30, 32 )

Type material. Holotype ♂, CHINA: Guangxi, Longzhou, Shuikou, 5–6 May 2009, coll. Ni Junqiang. Paratypes: 5 ♂ 1♀, same data as holotype; 2♀, Yunnan, Ruili, 15–18 July 2013, coll. Yang Weicheng, Wang Yingjian and Sun Haiyan; 1 ♂, Yunnan, Ruili, 14–15 August 2013, coll. Yang Weicheng and Wang Yingjian.

Length: ♂ 8.5–9.4 mm, ♀ 9.6–10.2 mm.

Coloration ( Fig. 7 ). Head and thorax dorsum yellow-green (♂) or yellow-brown (♀). Crown with median apical black spot and two same sized round spots each near lateral frontal sutures that extending to ocelli, disk of crown with central rhombic medium black spot, apical portion of crown with small and short brown stripes, eyes black-brown, ocelli yellow-brown bordered with black-brown. Face with two broad black-brown longitudinal stripes on the central of frontoclypeus, yellow-green oblique stripes over area of muscle impressions; clypellus with triangular black-brown spot on basal half. Pronotum and scutellum with three longitudinal brown stripes over disk of pronotum extending onto scutellum, the median one from anterior margin of pronotum to apex of scutellum, the lateral ones beginning from the median of pronotum ending the basal angles of scutellum, lateral pronotal margin narrowly bordered with brown. Forewing pale, basal half of anterior margin yellow, veins fuscous. Thoracic pleura, venter, and legs yellowish-brown, pretarsi black-brown. Abdomen orange.

External features. External characters much as in C. lata Young. Median length of crown 5/9 of interocular width; ocelli equidistant from adjacent anterior eye angle and median line.

Male genitalia. Pygofer ( Fig. 25 ) broad and long, well produced with posterior margin angularly convex; surface with macrosetae on posterior portion and short microsetae on half ventral portion. Subgenital plates ( Fig. 26 ) small, triangular, with uniseriate macrosetae and short microsetae along outer margin. In lateral view, aedeagus ( Fig. 28 ) with almost equal width from base to apex, basal half smooth, apical 2/5 portion rugged transversely, apex curved dorsally and forming nipple-shaped process, dorsal apodeme longer than shaft; in ventral view, aedeagus ( Fig. 27 ) shaft with apical 2/5 depressed laterally and rugose. Connective ( Fig. 29 ) Y-shaped, stem short. Style ( Fig. 30 ) stout, apex smoothly curved laterally and acutely pointed, with three microsetae subapically. Female 7th sternite ( Fig. 32 ), in ventral view, posterior margin broadly convex and undulate apically.

Etymology. The new species is named for the collector of the holotype.

Remarks. This new species is similar to C. lata Young, 1979 , but it differs from the latter in that the head and thorax dorsum are yellow-green ( Fig. 7 ); the aedeagal shaft is slender with almost equal width from base to apex in lateral view, the basal half is smooth, the apical 2/5 portion is depressed laterally and transversely rugose, and the apex is nipple-shaped ( Figs 27, 28 ).
