Abstract.
Systematic status of two Trechus species previously considered to belong to T. (s. str.) nakaguroi is scrutinized mainly on the basis of a comparative study of their male genitalia. One of them is described as a distinctive new species, T. sikhotealinus. The other is considered to be a full species, T. sachalinensis, though differentiation between this and T. nakaguroi is at a sibling stage. Brief notes are also given on the other species of the subgenus Trechus (s. str.) from Northeast Asia.
