As an natural enemy against the Monochamus alternatus Hope and M. saltuarius Gebler (Coleoptera: Cerambycidae), the vector species of the pine wood nematode (Bursaphelenchus xylophilus (Steiner & Buhrer), Dastarcus helophoroides (Fairmaire) (Coleoptera: Bothrideridae) is recognized for the first time in Korea. The family Bothrideridae is also reported for the first time in Korea. We provide the diagnosis, illustrations, biological information, and the host insects of D. helophoroides (Fairmaire).

Odontepyris sp. nov., a new ectoparasitoid on the caterpillar of Telorta divergens (Butler, 1879) (Lepidoptera: Noctuidae), is recognized from Korea. After rearing the larvae on the host insect, adult females were obtained and described. Revising all known species of genus Odontepyris, a key to the species of the genus Odontepyris is presented for the Eastern Palearctic region.
