Macrotrichia deltata View in CoL sp. n.

(Figs. 1, 3, 5, 7–17)

Description. Male. Body length (incl. forewing) 19–20 mm, head width (incl. eyes) 6–6.2 mm, pronotum width 9–10 mm. Body virescent, lateral margins of vertex and pronotum dark brown (Fig. 1). Eyes dark brown; ocelli red (Fig. 1). Tegmina with costal margin red; an infuscate spot on disc (Fig. 5).

Male 8th sternite with posterior margin concaved (Fig. 13). Pygofer side in lateral aspect tapering posteriorly, with a process blunt, curved ventrally (Fig. 11). Style with a triangular subapical process directed somewhat posteriorly, apex acuminate (Fig. 15). Aedeagus with a pair of elongate dorsal apodeme processes, curved dorsally; shaft slightly longer than apodeme process, tapering apically, slight curved dorsally in lateral view (Figs. 15–17); gonopore apical ventrally (Fig. 17).

Female. Body length (incl. forewing) 28 mm, head width (incl. eyes) 8 mm, pronotum width 14 mm. Other characteristics of female same as male.

Type material. Holotype: male, CHINA, Hainan Prov., Mt. Wuzhishan, 640m, 17 May 2007, Yani Duan; Paratypes: 3 males, same data as holotype; 1 male, CHINA, Hainan Prov., Mt. Jianfengling, 5 June 2007, Yani Duan, light trapped; 1 female, CHINA, Hainan Prov.: Mt. Diaoluoshan, 28 May 2008, Qiulei Men.

Etymology. The species name refers to the shape of the subapical process of style.

Remarks. This new species is superficially similar to M. hamata sp. n., but can be distinguished from the latter by: (1) pygofer caudal process blunt; (2) subapical process of style directed posteriorly; (3) aedeagal shaft long and curved dorsally, narrowing to sharp apex. The new species is also similar to M. flavomarginata (Kuoh & Cai) n. comb., but can be distinguished from the latter by: (1) aedeagus with paired processes arising dorsally; (2) subapical process of style along inner margin unforked.
