sp. nov.

Agnesiella (D.) hastata Wang & Huang sp. nov. ( Figs 41–44 View FIGURES 33–48 , 59 View FIGURES 49–60 , 134–139 View FIGURES 134–139 )

Measurement. Male, 3.10–3.30 mm (including wings).

Description. Body mostly dark brown ( Figs 41, 42 View FIGURES 33–48 ). Face largely dark brown ( Fig. 44 View FIGURES 33–48 ). 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 View FIGURES 33–48 ). 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 View FIGURES 49–60 ).

Abdominal apodemes extending to apex of 5th abdominal sternite ( Fig. 134 View FIGURES 134–139 ). 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 View FIGURES 134–139 ). 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 View FIGURES 134–139 ). Connective with prominent central lobe ( Fig. 137 View FIGURES 134–139 ). 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 View FIGURES 134–139 ).

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 View FIGURES 134–139 ).

Etymology. The specific epithet is derived from the Latin word “hasta”, referring to the halberd-shaped aedeagal shaft ( Fig. 138 View FIGURES 134–139 ).
