Wang, Junjie, Liu, Jialing, Zhang, Yalin & Huang, Min, 2024, Eight new species and four new records of the leafhopper genus Agnesiella Dworakowska (Hemiptera: Cicadellidae: Typhlocybinae) from China, Zootaxa 5537 (1), pp. 49-75 : 67-70

Agnesiella ( D.) elongata Wang & Huang sp. nov. ( Figs 33–36 , 57 , 121–126 )

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

Description. Body mostly brown ( Figs 33, 34 ). Face largely dark brown, frontoclypeal area light brown with brown transverse stripes, anteclypeus and lorum, genae mostly blackish brown, outer margins cream colored ( Fig. 36 ). Vertex brown in the middle, anterior margin with a pair of black patches. Pronotum mostly brown with some pale yellow areas, a longitudinal oval black patch near anterior margin medially, three black patches near each lateral margin; triangles brown, scutellum yellow ( Fig. 35 ). Forewing with beige area near anterior margin medially, basal 2/3 with light brown patches at base, middle and apical part; ScP+RA, MP''+CuA' veins and 3rd apical cell with brown patches, 2 dark brown patches at both ends of brochosome area ( Fig. 57 ).

Abdominal apodemes extending to middle of 6th abdominal sternite ( Fig. 121 ). Male pygofer with 2 long fine setal groups, several small rigid setae clustered on slightly protruded posterodorsal margin; a digitiform dorsally curved pygofer process on posteroventral margin ( Fig. 122 ). Subgenital plate with distal part bearing some long fine setae and small rigid setae, with a distinct protrusion subapically ( Figs 122, 123 ). Style with a subapical process nearly as long as apical part, forming an obtuse angle with apical part ( Figs 122, 123 ). Connective without prominent central lobe ( Figs 123, 124 ). Aedeagal shaft slender, basally with an extremely long, dorsally curved ventral process with minute teeth along dorsal subapical margin ( Figs 125, 126 ).

Specimens examined. Holotype: ♂, CHINA, Xizang Autonomous Region , Zayü County, 1540m, 5 Jun 2019, coll. Lü Lin. Paratype: 3♂ 2♀, same data as holotype ; 3♂ 1♀, CHINA, Xizang Autonomous Region , Motuo County, 1530m, 20 Jul 2022, coll. Qingquan Xue.

Remarks. The new species is similar to A. ( D.) longisagittata in the attachment site of the ventral process on aedeagal shaft, but differs in the following characteristics: pygofer process longer ( Fig. 122 ); subapical process of style larger ( Fig. 122 ); ventral process on aedeagal shaft unbranched ( Fig. 125 ).

Etymology. This specific epithet is derived from the Latin word “elongare”, referring to the extremely long ventral process on the aedeagal shaft ( Figs 125, 126 ).
