Abstract

A new species Euxaldar daweishanensis Yang, Chang & Chen, sp. nov. is described and illustrated from southwestern China. The female genitalia of the genus Euxaldar is described and presented for the first time. A checklist and key to the known species of the genus are provided. A revised molecular phylogenetic analysis of the family Issidae based on combined partial sequences of 18S, 28S, COI, and Cytb is provided using both Maximum likelihood and Bayesian inference analyses.

Keywords: Hemisphaeriini; Checklist; DNA sequence; identification key; morphology; planthopper; taxonomy.
