(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.
