Agnesiella (Draberiella) hastata Wang & Liu & Zhang & Huang 2024, sp. nov.

Agnesiella (D.) hastata Wang & Huang sp. nov. (Figs 41–44, 59, 134–139) Measurement. Male, 3.10–3.30 mm (including wings). Description. Body mostly dark brown (Figs 41, 42). Face largely dark brown (Fig. 44). Vertex mostly light yellow with a pair of brown patches along anterior margin. Pronotum largely blackish brown with some pale yellow areas, triangles blackish brown, scutellum yellow (Fig. 43). Forewing with one brown patch each at base, middle and apical part in basal 2/3; MP''+CuA' veins and 3rd apical cell with brown patches, brochosome area yellowish brown with a small blackish brown patch at each end (Fig. 59). Abdominal apodemes extending to apex of 5th abdominal sternite (Fig. 134). Male pygofer with 2 setal groups, several small rigid setae clustered on protruded posterodorsal margin; a digitiform pygofer process curved dorsally on postervoentral margin (Fig. 135). Subgenital plate with distal part bearing some long fine setae and small rigid setae, with a distinct protrusion subapically. Style with a tooth-like subapical process shorter than apical part, forming an obtuse angle with apical part (Figs 135, 136). Connective with prominent central lobe (Fig. 137). Aedeagal shaft with apex slightly protruded ventrally, slightly protruded dorsally near base (in lateral view), distinctly thicker at middle (in posterior view); ventral process with 2 digitiform branches, located on the upper and lower angles respectively, lower branch longer than upper branch (Figs 138, 139). Specimens examined. Holotype: ♂, CHINA, Sichuan Province, Liziping National Nature Reserve, 2000m, 9 Aug 2021, coll. Junjie Wang. Paratype: 1♂ 1♀, same data as holotype; 2♂ 1♀, CHINA, Xizang Autonomous Region, Motuo County, 80K, 2012m, 21 Aug 2021, coll. Qingquan Xue; 2♂, CHINA, Yunnan Province, Dali City, Mt. Cangshan, 2300m, 21 Jun 2022, coll. Junjie Wang. Remarks. The new species is similar to A. (D.) rita in the form of the aedeagal shaft, but differs in having the pygofer process with a single branch (Fig. 135). Etymology. The specific epithet is derived from the Latin word “hasta”, referring to the halberd-shaped aedeagal shaft (Fig. 138).
