Jiao, Meng & Yang, Maofa, 2015, Description of two new species of the leafhopper genus Karachiota (Hemiptera: Cicadellidae: Typhlocybinae: Dikraneurini) from China, Zootaxa 3915 (3), pp. 446-450 : 447

Karachiota recurva Jiao & Yang , sp. nov.

( Figs 1–16 )

Description. Length: male 3.2–3.3 mm, female 2.8–3.1 mm.

Body ( Figs 1, 2 ) slightly yellowish. Head ( Fig. 3 ) triangular. Vertex median length nearly the same as the width between the apex of eyes, coronal suture distinct, to the 1/3 of vertex. Crown slightly yellowish, front margin white, two white patches mesad of eyes. Pronotum yellowish, with several irregular white patches near front margin. Scutellum yellowish, two white longitudinal stripes centrally, side angle white. Face ( Fig. 4 ) compressed in lateral view. Anteclypeus ( Fig. 5 ) slender, lorum broad.

Forewing ( Fig. 6 ) slightly yellowish, with a small black spot on the basal part of the first apical cell, the fourth apical cell with a gray patch beside outer margin, the first apical cell nearly parallel with the second apical cell. Hindwing ( Fig. 7 ) semitransparent, anal vein branched.

Male abdomen ( Fig. 8 ) with apodemes of sternum II well developed. Pygofer ( Figs 9, 10, 15 ) very slender, sclerotised, with short dorsal appendage, distal part of pygofer with transverse striations. Subgenital ( Figs 15 ) triangular, greatly reduced and without setae. Paramere ( Fig. 11 ) strongly curved, two arms as long as each other. Aedeagus ( Figs 12, 13, 14 ) with shaft moderately long, broader at base and narrowed to apex, with pair of processes arising subapically and extended distad but not surpassing shaft apex, gonopore apical.

Type material. Holotype, ♂, Luodian, Guizhou, April. 1980, coll. by Zizhong Li. Paratypes, 2♂♂, 3♀♀, same data as holotype.

Etymology. The species name refers to the pair of upturned processes on the aedeagus.

Remarks. The new species differs from all other species of this genus by the absence of teeth on the processes of the aedeagus, and the presence of a pygofer appendage.
