The family Nitidulidae, the largest group in Cucujoidea, comprises approximately 350 genera and nearly 4,500 recorded species across ten subfamilies. In Korea, 86 species of Nitidulidae have been recorded. They are well-known for their diverse feeding habits. Anthophagy is a common habit, with certain species from the Epuraeinae, Carpophilinae, and Meligethinae recognized as pollinators. Despite their ecological significance, these groups rarely studied in Korea, due to their small size and morphological similarities. Our study reviews Korean species in three subfamilies, identifying 14 unrecorded species and 2 newly described species, and describes their ecological habits.
