Jiao, Meng & Yang, Maofa, 2015, Flatseta, a new genus of Dikraneurini (Hemiptera: Cicadellidae: Typhlocybinae) from China, with description of a new species, Zootaxa 3974 (1), pp. 140-144 : 141

Flatseta scimitara sp. nov.

( Figs. 1–27 )

Color as described for genus except crown with central part white, pronotum with central part pale-yellow, scutellum pale-yellow with two yellow patches. Male abdomen ( Fig. 7 ) with apodemes of sternum II extended to segment IV. Pygofer (Figs.8,9,14,15,18,19) with flat setae longer from inner side to outer side, with three kinds of hastate setaes: type a ( Fig. 16 ) with apex crescent shovel shaped; type b ( Fig. 16 ) with apex tapered to one side; type c ( Fig. 17 ) with apex tapered on both sides. Aedeagus stem (Figs. 11,12,13) base slightly broad, apex slender in ventral view, with paired apical processes shorter than stem, extended towards base, curved in lateral view, gonopore apical.

Female genitalia: Seventh sternite ( Fig. 23 ) with middle part acutely produced.

Measurements. Male 2.7–2.9mm (including wing); female 2.8–3.0mm (including wing).

Material examined. 1♂ [Holotype] China: Fujian Prov., Fuzhou, 30 June 1998, collected by Naijin Lin; [Paratype]: 3♂ 7♀, same data as holotype; 1♂ China; Yunnan Prov., Xishuangbanna, 29 August 2008, collected by Zhonghui Zhou.

Etymology. The species name refers to shape of the aedeagus apical processes.

Discussion. The new genus described above is important because the modified setae on the male pygofer are seldom seen in leafhoppers and this is the first time that such setae are used as a main character to distinguish a taxon of the tribe Dikraneurini . The male genitalia has the usual macrosetae ( Fig. 15 A) and microsetae ( Fig. 15 B), but the distal third of pygofer also has flat setae of three different shapes, indicated a, b, c in Figs. 16 and 17 .
