Abstract
Chen and He erected the genus Interphasma in 2008 (Chen & He, 2008). Thirteen species are recognized in this Chinese endemic genus which is distributed in eastern to south-western China (Chen & He, 2008; Chen & Zhang, 2008; Xu et al., 2010). In this paper, a new species, I. lizipingense sp. nov., is described and illustrated from Sichuan, China. A key to the species of the genus is given. The types are deposited in the Museum of Hebei University (HBU) and Hong Kong Entomological Society (HKEM). Full measurements are given to all the types in millimeter (mm.).
