Distribution patterns of Chinese Cixiidae (Hemiptera, Fulgoroidea), highlight their high endemic diversity

Three new species of the planthopper genus Oecleopsis Emeljanov, 1971 from China (Hemiptera, Fulgoromorpha, Cixiidae)

Three new species of the genus Oecleopsis Emeljanov, 1971 from China, O.acerbus Lv & Chen, sp. nov. and O.panxianensis Lv & Chen, sp. nov. from Guizhou Province, and O.digitatus Lv & Chen, sp. nov. from Sichuan Province, are described and illustrated. With these additions, the number of species in the genus is increased to 18. An updated identification key and checklist of all known species of Oecleopsis are provided as well as a map of their geographic distributions.

Taxonomic study of the genus Kuvera Distant, 1906 (Hemiptera, Fulgoromorpha, Cixiidae) with descriptions of two new species from China

Two new species of genus Kuvera Distant, 1906, Kuvera campylotropa Zhi & Chen, sp. nov. and K. elongata Zhi & Chen, sp. nov., and a new Chinese record, K. basarukini Emeljanov, 1998, are described and illustrated from China. The females of two other species of Kuvera, K. laticeps (Metcalf, 1936) and K. ussuriensis (Vilbaste, 1968), are described for the first time. An updated identification key to Chinese species of Kuvera is given.

Two New Species of Betacixius Matsumura, 1914 (Hemiptera: Fulgoromorpha: Cixiidae) from Southwestern China, with an Updated Checklist and Key to Species

Simple Summary

Betacixius Matsumura, 1914 is a small genus of cixiid planthoppers distributed throughout China, Japan and Vietnam. Despite its rich biodiversity in Southwest China, Betacixius has not been taxonomically well studied in this region. Here, two new species, Betacixius gongshanensis sp. nov. from Yunan Province and B. guizhouensis sp. nov. from Guizhou Province, are described, giving the genus 27 species in total. We believe that the discovery in this study will contribute to further studies on the classification and phylogeny of Cixiidae.

Abstract

In this study, two new species of genus Betacixius Matsumura, 1914 (Fulgoromorpha, Cixiidae), Betacixius gongshanensis sp. nov. from Yunnan Province and B. guizhouensis sp. nov. from Guizhou Province, are described and illustrated. An updated checklist and identification key to known species of the genus Betacixius are provided.
