Abstract

Lapicixius yixianensis sp. nov., the second species of this genus, is described and illustrated on the basis of an almost complete specimen from the Lower Cretaceous Yixian Formation of Liaoning Province, China. This new representative of the extinct hemipteran family Lalacidae increases the taxonomic diversity of the group during the Cretaceous. The affinities of the new fossil with described lalacid planthoppers and the validity of Lalacidae are discussed.
