Agnesiella (A.) hamaculeata Wang & Huang sp. nov. ( Figs 17–20 , 53 , 91–97 )

Measurement. Male, 3.10–3.25 mm (including wings).

Vertex pale brown medially, remaining parts mostly pale yellow, with a brown patches along anterior margin. Pronotum with anterior margin medially yellow, brown median area, some greyish-brown and blackish brown patches on remaining parts; triangles light brown, scutellum yellowish-brown basally, brown apically ( Fig. 19 ). Forewing with pale yellow area near anterior margin medially, basal 2/3 with one brown band each at base, middle and apical part; MP''+CuA' veins and 3rd apical cell with brown patches, one black patch at each end of brochosome area ( Fig. 53 ).

Abdominal apodemes extending to apex of 6th abdominal sternite ( Fig. 91 ). Male pygofer with some scattered setae, prominently extended posteroventral angle with some small protuberances; a horn-like pygofer process bearing 2 rigid setae ( Figs 92, 93 ). Subgenital plate with distal part bearing some long fine setae and small rigid setae; a distinct protrusion subapically, apex with a few peg-like setae ( Fig. 94 ). Style with a short, finger-like subapical process directed away from apical part ( Figs 94, 95 ). Connective stem slender, without prominent central lobe ( Fig. 94 ). Aedeagal shaft slender, apex with plate-like expansions dorsally and ventrally ( Fig. 96 ).

Specimens examined. Holotype: ♂, CHINA, Yunnan Province, Lijiang City, Laojun Mountain National Geopark, Liming Scenic Area , 2200m, 30 Jun 2022, coll. Junjie Wang. Paratype: 2♂ 2♀, same data as holotype ; 2♂, CHINA, Yunnan Province, Gongshan Derung and Nu Autonomous County, Bingzhongluo Town , 1700m, 12 Jun 2019, coll. Lü Lin ; 2♂ 1♀, CHINA, Yunnan Province, Lijiang City, Xinzhu Village , 2360m, 3 Jul 2022, coll. Junjie Wang.

Remarks. The new species is similar to A. (A.) nigroflava sp. nov., but differs in the following characteristics: abdominal apodemes extending to apex of 6th abdominal sternite ( Fig. 91 ); pygofer process with only 2 rigid setae ( Fig. 93 ); style with subapical process directed away from apical part ( Fig. 95 ).

Etymology. This specific epithet is derived from the Latin words “hamus” and “aculeus”, referring to the barbed, hook-shaped distal half of style ( Fig. 95 ).
