Two spider species of the genus Asiacoelotes collected from various areas of South Korea are reviewed with spination on each leg, detailed illustrations including trichobothrium patterns and SEM photographs of male palpal organs and female epigynum. These two species, A. songminjae (Paik &Yaginuma, 1969) and A. insidiosus (L. Koch, 1878), have been confused in Korea and Japan because they were previously incompletely described. A. songminjae is redescribed from the neotype and is here synonymized with A. tropidosatus (Wang & Zhu, 1991). A. insidiosus is recorded for the first time in Korea.
