Despite the enormous ecological success of insects elsewhere on earth, they have failed to colonize oceans. A significant portion of the marine littoral insect fauna consists of Coleoptera and the highest number of species belongs to the beetle family Staphylinidae. At present, over 400 species in 91 genera and eight subfamilies are confined to marine coastal habitats. Coastal Staphylinidae are polyphyletic, and have diverse adaptations of structure, physiology, and behavior. Aleocharinae contain the largest number of coastal species (about 200 species in 46 genera). Today I would like to briefly introduce my research program on the diversity, phylogeny, habitat evolution, and historical biogeography of the coastal Aleocharinae. Three selected aleocharine lineages containing many coastal species published with my colleagues are provided.

한국산 시베리아뽀족반날개속에 대한 분류학적 재검토를 시도하였다. 3종의 한국산 미기록종이 밝혀졌다 [Tachinus (Tachinoderus) nigriceps Sharp, Tachinus (Tachinus) sharpi Bernhauer & Schubert, and Tachinus (Tachinus) yezoensis Li]. 한국산 시베리아뾰족반날개속은 총 5종이 되며, 종 기재를 하였고 진단 형질을 도식하였다.

한국산 가는목도랑반날개 족의 분류학적 연구를 수행하였다. 국내에서 처음으로 보고되는 3종의 [Falagria sulcata (Paykull), Myrmecopora (Lamproxenusa ) rufescens (Sharp), and Myrmecocephalus sapida (Sharp)］검색표와 표본사진을 작성하였다.
