Abstract
Three new Stenus species of the indubius group from Sichuan Province, West-Central China, are described: S. zhuxiaoyui Tang, sp. nov., S. pectorifossatus Tang. sp. nov. and S. erlangshanus Tang, sp. nov. Diagnostic characters are illustrated and a key to Chinese species of this group is provided. The conflict between classifications of Stenus based on subgenera and species groups is briefly discussed. All three new species have diagnostic characters of the subgenus Hemistenus.References
