Taxonomic study of the genus Oecleopsis Emeljanov, 1971 (Hemiptera: Fulgoromorpha: Cixiidae: Pentastirini), with descriptions of three new species from China

摘要

This paper reviews the cixiid planthopper genus Oecleopsis Emeljanov, 1971. Twelve species are recognized in the genus worldwide, of which three new species from China are described and illustrated: O. spinosus sp. nov., O. tiantaiensis sp. nov., O. wuyiensis sp. nov. A key to all known species of this genus is presented. The cixiid planthopper genus Oecleopsis was established by Emeljanov (1971) for Oliarus artemisiae Matsumura, 1914, and belongs to the tribe Pentastirini in the family Cixiidae. VanStalle (1991) described the new species Oecleopsis articara, and transferred the following seven species from the genus Oliarus Stal, 1862 into the genus Oecleopsis: Oecleopsis yoshikawai (Ishihara, 1961), O. petasatus (Noualhier, 1896), O. mori (Matsumura, 1914), O. sinicus (Jacobi, 1944), O. bifidus (Tsaur, Hsu & Van Stalle, 1988), O. chiangi (Tsaur, Hsu & Van Stalle, 1988) and O. elevatus (Tsaur, Hsu & Van Stalle, 1988). While sorting and identifying Cixiidae from material in the Entomological Museum, Northwest A&F University (NWAFU), we found three new species of Oecleopsis, which are herein described and illustrated. Furthermore, all previously known species of Oecleopsis occurring in China are redescribed except for O. chiangi (no specimens available).
