Zanna robusticephalica sp. nov. (Hemiptera: Fulgoromorpha: Fulgoridae) from China, with comments on some ultrastructural characters of the new species.

Abstract

Zanna robusticephalica sp. nov. (Hemiptera: Fulgoromorpha: Fulgoridae: Zanninae: Zannini), representing the third species of the planthopper genus Zanna Kirkaldy, 1902 from China, is described and illustrated from Yunnan in southwestern China. Scanning electron micrographs of the antennal sensilla, rostral apex, hind tarsal segments, gonoplac and wax glands of the new species are provided. The generic diagnostic characters of Zanna are redefined and the autapomorphies are proposed to support the monophyly of the genus. A check-list of the Oriental Zanna species is included.
