In the process of revising the tachinid subgenus Linnaemya Robineau-Desvoidy of South Korea, three species are recognized as new to the country: Linnaemya pallidohirta Chao, L. scutellaris (Malloch) and L. lateralis (Townsend). They belong to the oralis species group of the subgenus. L. scutellaris (Malloch) and L. lateralis very closely resemble each other so that they need to be identified with caution. We here provide detailed redescriptions and illustrations with their diagnostic characters indicated.

In the process of revising the tachinid genus Linnaemya Robineau-Desvoidy in Korea, we have discovered two species for the first time in Korea. They closely resemble each other and need to be identified with caution. We here provide detailed redescriptions and illustrations with their diagnostic characters indicated. L. atriventris can be distinguished from L. hirtipennis by the combination of the following characteristics: 1) abdomen black in ground color; 2) wing vein R1 without setulose; 3) hypandrium without secondary posterior lobe; 4) male with antero-basal 1/3 of flagellomere I distinctly swollen; and 5) postgonite very weakly curved dorsally.

The genus Linnaemya Robineau-Desvoidy (Diptera: Tachinidae: Linnaemya) is one of the largest genera of the subfamily Tachininae including 149 recognized species worldwide. We reviewed Korean species of the subgenus Ophina belonging to the genus Linnaemya. As a result, we recognized three species, L.(Ophina) microchaetopsis Shima, L.(Ophina). picta (Meigen) and L.(Ophina) zachvatkini Zimin. Among them, the latter two species are reported for the first time from Korea. They belong to the haemorrhoidalis species group of the subgenus Ophina. We provide a generic key, descriptions and illustrations of the species.

Linnaemya Robineau-Desvoidy (Diptera, Tachinidae) is one of the largest genera of the subfamily Tachininae with more than 149 described species in the world. In Korea, only three species have been known to date. In this study, the genus Linnaemya in Korea was reviewed. All available material was examined to identify the species of the genus. Based on the present study, we described a new species. Also ten species are reported for the first time from Korea: L. comta, takanoi, tessellans, ambigua, kanoi, zachvatkini, picta, pallidohirta, scutellaris, and lateralis. We provide a generic key, illustrations, and photos of the species of the genus. A phylogenetic analysis was also conducted to infer interspecific relationships among Korean Linnaemya species using a software, PAUP, with an outgroup Lypha dubia.
