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

Agnesiella (D.) chelata Wang & Huang sp. nov. ( Figs 29–32 , 56 , 114–120 )

Measurement. Male, 3.35–3.45 mm (including wings).

Description. Body mostly dark brown ( Figs 29, 30 ). Face mostly brown, frontoclypeal area with dark brown transverse stripes, lorum brown, genae largely blackish brown ( Fig. 32 ). Vertex yellowish-brown medially with a brown patch along anterior margin connecting the 2 lateral black patches. Pronotum largely brown, with one blackish brown patch near anterior margin medially and at each anterolateral angle; triangles dark brown, scutellum light yellow ( Fig. 31 ). Forewing with some brown bands in basal 2/3, 2nd and 3rd apical cells smoky brown; brochosome area yellowish-brown with a blackish brown patch at each end ( Fig. 56 ).

Abdominal apodemes extending to base of 6th abdominal sternite ( Fig. 114 ). Male pygofer with an annulate setal group near posterior margin, several small rigid setae along protruded posterodorsal margin; a bifurcate pygofer process with a common robust stem on middle of posterior margin ( Fig. 115 ). Subgenital plate with distal part bearing some long fine setae and small rigid setae; a distinct protrusion subapically ( Figs 116, 117 ). Style with a short horn-like subapical process forming an obtuse angle with apical part ( Figs 116, 118 ). Connective without prominent central lobe ( Fig. 116 ). Aedeagal shaft with a plate-like ventral expansion apically, a dorsal plate-like expansion subapically, with a bifurcate ventral process at middle, upper branch small and directed towards shaft apex, robust lower branch curved towards the left side of shaft ( Figs 119, 120 ).

Specimens examined. Holotype: ♂, CHINA, Yunnan Province, Dali City, Mt. Cangshan , 2300m, 22 Jun 2022, coll. Junjie Wang and Zhou Xian. Paratype: 4♂ 2♀, same data as holotype ; 2♂, CHINA, Yunnan Province, Gongshan Derung and Nu Autonomous County, Shuanglawa Village , 1800m, 17 Jun 2019, coll. Lü Lin ; 2♂ 1♀, CHINA, Yunnan Province, Ailaoshan National Nature Reserve , 2200m, 6 Jun 2022, coll. Junjie Wang ; 2♂ 1♀, CHINA, Yunnan Province, Gaoligongshan National Nature Reserve , 1650m, 16 Jun 2022, coll. Junjie Wang ; 1♂ 1♀, CHINA, Yunnan Province, Lijiang City, Xinzhu Village , 2360m, 3 Jul 2022, coll. Junjie Wang ; 1♂, CHINA, Yunnan Province, Huanglianshan National Nature Reserve , 1650m, 10 Jun 2023, coll. Lü Lin.

Remarks. The new species is similar to A. (D.) rita , but differs in the following characteristics: pygofer process arising from the middle of posterior margin, and bifurcated into upper and lower branches ( Fig. 115 ); robust lower branch on aedeagal shaft curved towards the left side of shaft ( Figs 119, 120 ).

Etymology. This specific epithet is derived from Latin word “chela”, referring to the bifurcate pygofer process with a common robust stem ( Fig. 115 ).
