Yan, Bin & Yang, Mao-Fa, 2019, Chinese species of the genus of Agnesiella Dworakowska (Hemiptera: Cicadellidae: Typhlocybini), with four new species and four new records, Zootaxa 4565 (2), pp. 151-170 : 153-154

Agnesiella (D.) furca sp. nov.

( Figs 16–21 , 50–53 , 85–90 )

Diagnosis. Male. Length 3.2 mm ( Fig. 16 ). Dorsum mostly dark brown. Pronotum brown, with seven dark patches, central part sordid beige, hind margin of pronotum light grey. Mesonotum brown except anterolateral triangles dark brown. Scutellum dark on apex ( Figs 16, 18 ). Face dark, with two yellowish patches near anterior margin ( Figs 17, 18 ). Forewing brownish, with symmetrical grey patches basally ( Figs 16, 18 , 50 ).

Ventral appendage of pygofer small, distinctly shorter than in other species of subgenus except Agnesiella farida Dworakowska, 1994 ( Fig. 85 ). Paramere robust, subapical tooth longer than in Agnesiella digita sp. nov. ( Figs 74 , 88 ). Ventral process of shaft on aedeagus with bifurcated at apex, petiole of process elongate ( Figs 89, 90 ).

Female. Length 3.1 mm. Face black except frontoclypeus brownish, and lower part of eyes with yellowish ( Figs 19–21 ). Other coloration as in male.

Type material. Holotype, ♂, Xishan Mountain, Kunming city, Yunnan Province, 14 Oct. 2010, coll. Mao-fa Yang. Paratypes, 3♂♂ 1♀, same data as the holotype .

Etymology. The species name is derived from the Latin word furca, meaning “bifurcated”, and refers to the apex of ventral process on aedeagus.

Remarks. This species is similar to Agnesiella (D.) azra Dworakowska, 1994 , but differs in having the ventral appendage shorter, and the subapical tooth bigger the aedeagus with the petiole of the ventral process more elongate, and the branchs divergent at less than 90 degrees.
