Diagnosis. Tachinus (Tachinoderus) kobensis is similar to T. (Tachinoderus) nigriceps in the appearance and shape of aedeagus but can be distinguished by dark-colored pronotum and longer sclerotized tube of inner sclerite of aedeagus. For detailed redescription, see LI (1995b: 208).

Biology. This species is often collected from leaf litter.

Distribution. Japan (Hokkaido, Honshu (incl. Oki Isl.), Izu-shotô Isls. (Mikura-jima Is.), Shikoku, Kyushu (incl. Amakusa-shotô Isls., Gotô-rettô Isls., Tsushima Is.), Yaku-shima Is.). It is recorded from Hokkaido, Izu-shotô and Gotô-rettô for the first time. ULLRICH (1975) recorded this species from Tsushima as T. nigriceps (for details, see remarks on T. nigriceps nigriceps ).

Diagnosis. Tachinus (Tachinoderus) naomii can be distinguished from other members of the subgenus Tachinoderus by the combination of the following characters: elytra without microsculpture; male sternite VII with a row of granules along posterior margin, and a small patch of granules at base of triangular impression; apical halves of parameres of aedeagus strongly narrowed; outer lobes of female tergite VIII with two long and six short bristles along each external margin (modified after LI, 1995b). For detailed description, see LI (1994: 661).

Distribution. Japan (Amami-Ôshima Is.), China.

Remarks. SHIBATA et al. (2013) listed this species for Taiwan, but this record is erroneous ( CHANG et al. 2019).
