I have never seen this species, so all discussions below are based on literature data. Distribution: Korea, Japan.

Notes. T. koreanus is a quite conspicuous species with 11-segmented antennae. Because of this feature it could be placed in the genus Leptothorax , but on the other hand, it well differs from all known species of that genus by its distinctly marked and slightly angulated humeri (seen from above), and by the very long propodeal spines, which are similar to those of T. nassonovi and related species. I assume that the taxonomic position of T. koreanus is still uncertain.
