An analysis of Lysiphlebus Foerster species reared from various field-collected aphid species determined the presence of probably trans-palearctic L. fabarum (Marsh.), L. testaceipes (Cress.) which is an accidentally introduced and established immigrant from North America, and L. koraiensis Stary sp. n., a native species of presumably broader distribution. Both parthenogenetic and biparental populations of L. fabarum were identified in Korea.
