The Rogadinae is richness species subfamily containing more than 1,242 described species grouped in 62 currently recognized genera (Yu et al., 2016). Most members in Rogadinae are koinobiont endoparasitoids wasps characterized ‘mummifying’ their lepidopteran host larvae. It was known that the rogadine wasps mainly attack various lepidopterans. The genus Aleiodes is a large genus of subfamily Rogadinae, approximately about 632 described species worldwide (Yu et al., 2016), which almost attacks macrolepidopterans (Zaldívar-Riverón et al., 2008). Furthermore, some of them are very beneficial as biological control agents to host forest pests, such as gypsy moth, cutworms, and fall webworm (Shaw, 2006). To date, 32 species of the genus Aleiodes have been recorded in the National Species List of South Korea (NIBR, 2020). In this study, Aleiodesthirakupti is reported, for the first time, from Korea, which has formerly been described in Thailand (Yu et al., 2016). Here, redescription, diagnosis, distribution and illustrations are provided.

Materials and Methods

Aleiodes species recently collected by sweeping, mountain 43, Goseo-ri, Bigeum-myeon, Sinan-gun, Jeonnam, South Korea. The samples were preserved in 75% ethyl alcohol. The species studied are deposited in Kunsan National University (KSNU). The terminology used for morphological characters follows Achterberg (1988) For observation and photography, LEICA DMC2900 digital camera and LEICA M205 C microscope (Leica Geosystems AG) were used. Images were stacked by using Helicon software (Helicon Soft). Abbreviations are as follows: CU; cubitous vein, SC; subcostal vein, R; radial vein, SR; subradial vein, T; tergite.
