Yan, Bin & Yang, Mao-Fa, 2017, Taxonomic study of the leafhopper genera Farynala Dworakowska and Xaniona Zhang & Huang (Hemiptera: Cicadellidae: Typhlocybinae: Typhlocybini), with descriptions of three new species from China, Zootaxa 4276 (4), pp. 519-528 : 520

Farynala dextra sp. nov.

( Figs 1–4 , 13–22 )

Type material. Holotype, ♂, Yingshan, Huanggang , Hubei Province, 23–27 June 2014, coll. Meng Jiao. Paratypes, 5 ♂♂, same data as holotype.

Length of male 2.6–2.7 mm.

Coloration. Body color pale yellow to yellowish; eyes brown-gray; face light beige, with brownish transverse striae on sides of frontoclypeus ( Fig. 4 ). Pronotum beige yellowish, slightly darkened in center. Basal triangles slightly infuscated on mesonotum. Forewing translucent, with two irregular dark patches, one on posterior margin just proximad to base and other on end of first apical cell ( Figs 1–4 , 14 ).

External features. Head strongly convex in front; coronal suture distinct and extending beyond anterior margin of eyes; length of crown less than interocular width; pronotum wider than crown. Face slightly elevated. Scutellar suture distinct. Forewing with third apical cell triangular, petiolar. Hindwing relatively broad at apex ( Figs 1–4 , 14, 15 ).

Abdominal apodemes ( Fig. 16 ) reaching apex of 6th sternite.

Male genitalia. Pygofer well produced, gradually narrowed towards apex and slightly curved posterodorsally margin. Lobe of pygofer with two groups of macrosetae near lower margin in lateral view, one group (two macrosetae) near base, other on posteroventral margin; hind margin of pygofer lobe with several short macrosetae and many small teeth on posteroventral margin, numerous microsetae on posterodorsal margin ( Fig. 13 ). Subgenital plate parallel sided, with distal third abruptly curved dorsad; with one basal macroseta, and with scattered numerous microsetae; row of short and stout setae at lateral margin and several small peg-like microsetae at apex ( Figs 13, 17 ). Paramere strongly curved dorsad at apex and broadened at distal middle part, with row of microsetae on lateral margin, not ornamented with teeth basally ( Figs 13, 18, 19 ). Connective trapezoidal ( Fig. 18 ). Aedeagus preatrium weakly developed, dorsal apodeme well developed; aedeagal shaft partly covered by membranous; with 3 asymmetrical processes, 2 apical processes curved (apical process of right side strongly curved ventrad and pointed to opposite side), one straight middle right process not extending to apex of shaft; gonopore apical ( Figs 20–22 ).

Etymology. The species name refers to the middle process on the right side of the aedeagal shaft.

Remarks. This new species is very similar to F. extremita Dworakwoska in coloration and male genitalia structure but differs in having, when viewed in lateral aspect, the aedeagus more robust, with covered membrane on the shaft, and the shorter lateral process arising closer to the base and extended only slightly beyond the shaft midlength. The paramere is also more curved and the apex more slender in F. dextra sp. nov..
