Abstract

A new genus of idiocerine leafhoppers (Hemiptera, Auchenorrhyncha, Cicadellidae) from China, Chinaica Zhang, gen. nov., is described, with two new species: Chinaica myrica Zhang, sp. nov., (the type species) and Chinaica viraktamathi Zhang, sp. nov. Specimens were collected from waxberry, Myrica rubra (Lour.) Siebold & Zucc. (Myricaceae). The new genus is distinguished by its external morphology and male genital structures and is compared to similar genera.

Myrica tristigma N.T.Cuong, T.D.Binh & D.V.Hai, sp. nov.  

Shrubs, monoecious, 1–2,5 m tall. Ovary glabrous, stigma sessile, divided into 3 branches. Drupe usually 1 per infructescence, globose, 0.8–1 cm diam.

Etymology. The species epithet is based on the character of the stigma divided into three relatively long branches.
