Abstract: Agnesiella (D.) biprotrusa Huang & Zhang sp. nov. (Figs 25–28, 55, 106–113) Measurement. Male, 3.2–3.40 mm (including wings). Description. Body yellowish-brown (Figs 25, 26). Face mostly light brown, frontoclypeal area with dark brown transverse stripes, anteclypeus blackish brown, lorum brown, genae largely blackish brown (Fig. 28). Vertex orange-red medially with a pair of dark brown patches along anterior margin. Pronotum with brown median area, remaining parts largely dark brown patches; triangles blackish brown, scutellum pale yellow outer margins of scutum and scutellum orange-red (Fig. 27). Forewing with one brown patch each at base, middle and apical part in basal 2/3; 1st, 3rd apical cells and ScP+RA vein with some brown patches, brochosome area yellowish-brown with a blackish brown patch at each end (Fig. 55). Abdominal apodemes extending to apex of 5th abdominal sternite (Fig. 106). Male pygofer with a long fine setal group near posterior margin, several small rigid setae clustered on protruded posterodorsal margin; a small horn-like pygofer process on posterior margin (Figs 107, 108). Subgenital plate with distal part bearing some long fine setae and small rigid setae; a distinct protrusion subapically, apex with peg-like setae (Figs 109, 110). Style with a very small subapical process (Fig. 111). Connective without prominent central lobe (Fig. 109). Aedeagal shaft sinuate, with a plate-like ventral expansion apically, a bifurcate ventral process at middle with upper branch longer than lower branch, both digitiform branches directed dorsally (Figs 112, 113). Specimens examined. Holotype: ♂, CHINA, Sichuan Province, Moxi County, 1600m, 4 Nov 1999, coll. I. Dworakowska. Paratype: 1♂ 1♀, same data as holotype; 1♂, CHINA, Yunnan Province, Gongshan Derung and Nu Autonomous County, Bingzhongluo Town, 1700m, 12 Jun 2019, coll. Lü Lin; 2♂ 1♀, CHINA, Yunnan Province, Gaoligongshan National Nature Reserve, 2050m, 18 Jun 2022, coll. Junjie Wang; 2♂, CHINA, Yunnan Province, Huanglianshan National Nature Reserve, 1650m, 10 Jun 2023, coll. Lü Lin. Remarks. The new species resembles A. (D.) longisagittata in the male genitalia, but differs in having a sinuate aedeagal shaft and the bifurcate ventral process situated at the midlength of the shaft (Fig. 112). Etymology. This specific epithet is derived from Latin words “bis” and “protrudere”, referring to the bifurcate ventral process of the aedeagal shaft (Figs 112, 113).
