The present study deals with four species of interstitial Collembola from South Korea. They are new to science and as follows : Pseudonurida longisetosa n.sp., Onychiurus donjiensis n. sp., O. jindoensis n. sp.m, and Folomia minuta n. sp.. Two speices of them, Pseudanurida longisetosa and Folsomia minuta n. sp. were collected from shell heap. So far eleven halophilous species of Collembola, including species to be recorded in this paper, were reported from the Korean peninsula.

This study deals with 8 species in 3 families of Collembola including 6 new records of Korea. They are Oudemansia esakii (Kinoshita, 1932), Axelsonia littoralis (Moniez, 1890), Sinella (S. str.) straminea (Folsom, 1899), Sinella (S. str.) coeca (Schott, 1899), Entomobrya marginata (Tullberg, 1871), and Willowsia bimaculata (Borner, 1909). Among them Oudemonsia esakii, Axelsonia littoralis and Entomobrya marginata are halophilous species. Sinella straminea and Sinella coeca were collected from nests of ants comprising the first report of myrmecophilous Collembola from Korea. The Collembolan fauna of Korea is accordingly listed as 203 species in 10 families.

In order to investigate the population structure and dynamics of halophilous springtails and ants at seashores in Korea, we made quantitative collection from three different sites having different vegetation and environment. The pH, salinity, and electric conductivity of the three sites were measured in order to find environmental factors influencing on their species composition and distribution. In view of the results so far obtained, the species composition and distribution of springtails seemed to depend not so much on pH and vegetation as on soil texture and salinity. On the other side, ant populations seemed to depend on vegetation in sand area and on inundation in both sand area and salt marshes. In all investigated sites, the species diversity in supra littoral zones was higher than in intertidal zones, and among intertidal zones of sand beach and salt marshes it was the highest at the upper zone of the sand beach.
