Fang, Yongqin & Xing, Jichun, 2018, Review of the leafhopper genus Longicornus Li & Song (Hemiptera: Cicadellidae: Deltocephalinae) with description of two new species, Zootaxa 4462 (3), pp. 435-442 : 439

Longicornus furcatus sp. nov.

Figs. 7–9 ; 27–33

Description. Vertex yellowish brown with some black stripes. Eyes brown. Pronotum with irregular yellowishbrown stripes ( Fig. 7 ). Face with frontoclypeus broadly yellowish brown dorsally, without dark transverse streaks on both sides ( Fig. 9 ).

External features as in generic description.

Male genitalia. Male pygofer side broadly rounded in lateral aspect, with 7 long postero-ventral setae ( Fig. 27 ). Aedeagal shaft short and robust, with pair of furcate processes arising from ventral margin near base; gonopore apical ( Figs. 30, 31 ). Connective with arms nearly 1/3 length of stem ( Fig 32 ).

Measurement. Length (including tegmen): Ƌ, 5.4–5.6 mm; ♀, 6.1–6.4 mm.

Type Material. Holotype: 1 ♂, China: Sichuan Prov., Ya’an, Erlangshan , 4 August 2005, coll. Zhonghui Zhou ( GUGC) ; Paratypes: 2♂♂ 4 ♀♀, same data as holotype .

Remarks. The new species is similar to L. flavipuncatus Li & Song, 2008, but can be distinguished from the latter by the pale dorsal part of the frontoclypeus and the short and robust aedeagus with a pair of furcate processes arising from the ventral margin near the base.

Etymology. The species name is derived from the Latin word “ furcatus ”, referring to the aedeagal shaft with a pair of furcate processes.
