The genus Toxares (Braconidae: Aphidiinae) is reported for the first time in Korea. Members of Toxares are known as solitary koinobiont endoparasitoids especially specific for aphidine aphids. In this study, Toxares deltiger (Haliday, 1833) is found as new to Korea, which has a wide host range for 31 aphid species within Aphidinae. Thus, this species would be useful as natural enemy for biological control in the future. Diagnosis and host information are included.
