Abstract
BACKGROUND: The subfamily Alysiinae is a relatively large group within the family Braconidae, comprising more than 2,440 valid species worldwide. It is divided into two tribes, Alysiini and Dacnusini and is characteried by koinobiont endoparasitoidism of dipteran larvae. In South Korea, 286 species from 21 genera have been recorded to date. Despite this diversity, genus Mesocrina have not previously been reported from the Korean Peninsula. Mesocrina includes species are parasitoids of cyclorrhaphan Diptera inhabiting fungi, while Alloea species are known as parasitoids of Lonchoptera species. For the genus Alloea, only one species has been recorded in Korea. These genera can be distinguished by specific morphological traits, such as wing venation and shape of mandible. NEW INFORMATION: Mesocrina indagatrix Foerster, 1863 is recorded for the first time from Korea, and the genus is recorded new for Korea. In addition, Alloea veles Belokobylskij,1997 is recorded for the first time in Korea, which represents the first record of Alloea veles outside from Russia and the second record of Alloea from Korea. The barcode region of mitochondrial cytochrome c oxidase I (COI) was also analyzed for the species. Also, we provide an identification key for the Alloea species recorded from Korea.
