Three species of minute-sized spiders were discovered for the first time in Korea: Theridiosoma fulvum (Theridiosomatidae), Microdipoena ogatai and M. shenyang (Mysmenidae). Previously, T. fulvum and M. ogatai were known to be distributed only in Japan, while M. shenyang was known only in Northeast China. All former records of Microdipoena jobi from Korea are misidentifications of M. shenyang. Detailed descriptions and photographs of the three species are provided.
