Macrotrichia hamata sp. n.

(Figs. 2, 4, 6, 18–23)

Description. Male. Body length (incl. forewing) 20 mm, head width 6–6.4 mm (incl. eyes), pronotum width 11.5– 12 mm. Body ochraceous, lateral margins of vertex and pronotum umber (Fig. 2). Eyes umber; ocelli red (Fig. 2). Tegmina with costal margin sanguineous; an infuscate spot on disc (Fig. 6).

Male 8th sternite slightly broad, with caudal margin concaved (Fig. 20). Pygofer side tapering posteriorly in lateral aspect, apex with a slender process, curved ventrally (Fig. 18). Style with a small subapical process directed anteriorly, apex acuminate (Fig. 21). Aedeagus with a pair of dorsal basal processes strong and slightly short, apex curved dorsally; shaft straight, slightly shorter than apodeme process, base protruding ventrally, apex abruptly tapering dorsally in lateral view and rounded in ventral view (Figs. 21–23); gonopore ventroapical (Fig. 23).

Type material. Holotype: male, CHINA, Yunnan Prov., Yunxian, 1100m, 12 July 1980, Ming Zhang. Paratype: 1 male, CHINA, Yunnan Prov.: Cangyuan, 675m, 8 June 1980, Yaoyun Yin.

FIGURES 11–17. Macrotrichia deltata sp. n. 11, pygofer, subgenital plate and anal tube, lateral view; 12, subgenital plate, ventral view; 13, male 8th sternite, ventral view; 14, apex of female abdomen, ventral view; 15, aedeagus, styles and connective, dorsal view; 16, aedeagus, lateral view; 17, aedeagus, ventral view.

Etymology. The species name refers to the shape of the subapical process of style. Remarks. This new species can be easily distinguished from M. flavomarginata (Kuoh & Cai) n. comb. by its paired processes of aedeagus arising from dorsal apodeme and an unforked subapical process of style along inner margin, and from M. deltata sp. n. by its shorter and stouter aedeagus as well as a hook-like process of style.
