Karachiota aristata Jiao & Yang , sp. nov.

( Figs 17–28 )

Description. Length: male 2.8 mm.

Body ( Fig. 17 ) yellowish. Head ( Fig. 18 ) triangular. Vertex median length longer than the width between the apex two of eyes, coronal suture distinct to the 1/3 of vertex. Crown yellowish, front margin white. Pronotum yellowish, lateral margin whity. Scutellum yellowish, two small white patches near the central, the side angle white. Face ( Fig. 19 ) compressed in lateral view. Anteclypeus ( Fig.20 ) slender, lorum broad.

Forewing ( Fig. 21 ) slightly yellowish, with a small black spot on the basal part of the first apical cell, the first apical cell nearly parallel with the second apical cell. Hindwing ( Fig. 22 ) semitransparent, anal vein branched.

Male abdomen ( Fig. 23 ) with apodemes of sternum II well developed. Pygofer ( Figs 24, 25 ) very slender, sclerotised, distal part of pygofer with transverse striations. Subgenital plates triangular, greatly reduced and without setae. Paramere ( Fig. 26 ) curved, scimitar-like. Connective V-shaped. Aedeagus ( Figs 27, 28 ) shaft with pair of subapical lateral processes not symmetrical, one process with aristate branch basally. Gonopore subapical.

Type material. Holotype, ♂, Jianfengling, Hainan, 3. April. 2013, coll. by Meng Jiao.

Etymology. The species name refers to the aristate process on the aedeagus.

Remarks. The new species is similar to Karachiota recurva sp. nov., but it differs from the latter in having the aedeagus processes asymmetrical and extended basad rather than distad.
