Abstract

Male genitalia of the species Cerynia lineola Melichar is described and illustrated for the first time from China. Colour polymorphism in a planthopper species Cerynia maria (White, 1846) is investigated based on some specimens from China, and a map showing the geographic distribution of this species is also provided. The examined specimens are deposited in the Institute of Entomology, Guizhou University, Guiyang, China (GUGC).

Highlights

The flatid genus Cerynia (Hemiptera: Fulgoromorpha: Flatidae) was established by Stål (1862) with Flata albata Stål, 1854 from Malaya as its type species
Melichar (1901) described three new species: C. fulgida from Indonesia, Cerynia trilineata from Indonesia and C. lineola from China, and proposed the new combination C. monacha
10 species were known and all species are distributed in the Oriental Region, including 4 from China and most are distributed in southern China

Summary

Introduction

The flatid genus Cerynia (Hemiptera: Fulgoromorpha: Flatidae) was established by Stål (1862) with Flata albata Stål, 1854 from Malaya as its type species. Melichar (1901) described three new species: C. fulgida from Indonesia, Cerynia trilineata from Indonesia and C. lineola from China, and proposed the new combination C. monacha Medler (1996) added a new species C. mixana based on the Walker’s (1851) identification specimen, and later he (1999) placed C. nigropustulata Schmidt, 1904 as a junior synonym of C. maria (White, 1846). 10 species were known and all species are distributed in the Oriental Region, including 4 from China and most are distributed in southern China Among these species, the male genitalia of C. lineola has not been described and illustrated. We described and illustrated the male genitalia of C. lineola Melichar, 1901 based on specimens from China (Hainan) for the first time, and provided data on colour polymorphism of the species C. maria (White, 1846) in populations from China.
