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 : 440

Longicornus biprocessus sp. nov.

Figs.10–12 ; 34–40 .

Description. General appearance as in Longicornus furcatus sp. nov., but body color darker and frontoclypeus with dark, transverse streaks.

Male genitalia. Pygofer side elongate, base wide, apex narrow, with numerous macrosetae on posterior area ( Fig. 34 ). Aedeagal shaft tapered in lateral view, with two pairs of processes: one pair spiniform and arising from ventral margin near base; other pair long and slender, arising from mediodorsal margin, extended to apex of shaft and directed caudally. Gonopore apical on dorsal side ( Figs.37, 38 ). Connective with arms nearly 1/5 length of stem ( Fig. 39 ).

Measurement. Length (including tegmen): Ƌ, 5.7–5.9 mm; ♀, 6.8 mm.

Type Material. Holotype: 1 ♂, China: Sichuan Prov., Chongzhou, Anzihe , 28 July 2016, coll. Bin Yan ( GUGC) ; Paratypes: 2♂♂ 1 ♀, same data as holotype ( GUGC) .

Remarks. The new species is similar to L. flavipuncatus but can be distinguished from the latter by the long aedeagal shaft with two pairs of processes medially on the dorsal margin.

Etymology. The new species name is derived from the Latin words “ bi -”and “ processus ”, referring to the aedeagus with two pairs of processes.
