Wang, Junjie, Zhang, Yalin & Huang, Min, 2022, Taxonomic study of the leafhopper genus Agnesiella Dworakowska (Hemiptera Cicadellidae: Typhlocybinae) from China, with descriptions of 13 new species, Zootaxa 5094 (2), pp. 201-233 : 210-213

Agnesiella (A.) protensa Huang & Zhang sp. nov.

( Figs 2, 6, 10, 14 , 71–79 )

Measurement. Male, 3.15 mm (including wings).

Body yellowish ( Figs 2, 6 ). Face with brownish transverse streaks on yellowish frontoclypeal area, anteclypeus and lorum yellowish, remaining parts ivory ( Fig. 14 ). Pronotum with 3 patches blackish. Most of scutellum brown ( Fig. 10 ). Forewing yellowish with a longitudinal brown patch on clavus extended from inner angle to near apex along posterior margin; patches on apical half smoky infuscate, patch at distal end of CuA vein brownish; brochosome field yellowish ( Figs 2 , 71 ).

Abdominal apodemes reaching end of 4th abdominal sternite. Posterior margin of male pygofer side obtuse with a short horn-like appendage bearing 4 rigid microsetae ( Figs 72, 73 ). Subgenital plate with some fine setae terminally and a lamellar subapical protrusion centrally on outer side ( Figs 74, 75 ). Paramere stout with 2 digitiform subapical protrusions, upper protrusion horizontally line with caudal apex forming T-shaped caudal end ( Figs 76, 77 ). Connective with stem nearly as long as lateral arms and central lobe distinct ( Fig. 74 ). Aedeagal shaft arched with narrow ridged ventral appendage approximately on apical half ( Figs 78, 79 ).

Specimens examined. Holotype: ♂, CHINA, Sichuan Province, Wolong , 2100m, 26-X-1999, coll. I. Dwora- kowska . Paratype: 1♂, same data as holotype .

Etymology. The specific name is derived from Latin word “protensus which means “prolong, referring to the extension of the caudal apex of the paramere in a straight line with the upper subapical protrusion, which resembles a reverse extension of the caudal apex ( Figs 76, 77 ).

Notes. The new species resembles Agnesiella (A.) juglandis , but differs in the T-shaped apex of the paramere ( Fig. 77 ) and narrower ventral appendage of the aedeagal shaft in lateral view ( Fig. 78 ).
