Abstract

This study provides detailed descriptions and illustrations of a new species, Psilota nigritarsa Huo & Zhao, sp. nov., and a newly recorded species in China, P. nigripilosa Shiraki, 1968. It also offers additional measurements for Psilota bashanensis Huo, Zhao & Liu, 2022. The paper proposes a reclassification of the P. innupta-group in the Palaearctic Region into two subgroups based on the morphology of the male genitalia. An updated taxonomic key for the species of the P. innupta-group within the Palaearctic Region is also provided.
