The genus Xenylla Tullberg in the family Hypogastruridae is cosmopolitan, containing about 131 species at present in the world. However, the genus Xenylla of Asia has been very poorly investigated; in Japan, four species, X. acauda Gisin, X. arenosa Uchida & Tamura, X. brevispina Kinoshita, and X. longicauda Folsom, were recorded, only three species, X. boerneri Axelson, X. changlingensis Wu and Yin, and X. changchunensis Wu and Yin, was known to occur in China. In Korea, the first recognizable species of the genus Xenylla was only one listed by Lee in 1973: Xenylla brevispina Kinoshita, 1916. Later Park et al (2005) added four new species, X. convexopyga, X. dotata, X. longistriata, and X. marina, which collected from litter of coniferous and broad-leaved trees, soil layer of a deciduous forest and dry accumulated organic matter on the margins of saline water. One new species of the genus Xenylla that were found from Korea is found. The new species characterized by labral setae arrangement and tiny anal spines. The present species resembles X. dotata in the arrangement of dorsal and ventral setae. But it is easily distinguished from X. dotata by the length ratio of furca, morphology of mandible, the shape of dorsal setae upon fourth antennal segment, and the length of anal spine. As result of this study, Korean faunal list of Xenylla adds up to 6 species.

연안생태계의 호염성 톡토기와 개미군집의 생물다양성정도와 변동에 대해 알아보기 위해, 주변환경과 식생이 다른 세지역에서 정량채집을 실시하였다. 종조성이나 분포에 영향을 주는 요인을 찾기 위해 pH, 염도 및 전기전도도를 측정하였다. 연구결과 톡토기의 종조성 이나 분포에는 pH와 식생보다도 토성과 염도가 더 큰 영향을 주는 것으로 나타났다. 그러나 개미의 경우는 집을 지을 적당한 장소를 제공해 줄 수 있는 식생과 조수에 의한 침수에 더 큰 영향을 받는 것으
