The family Braconidae is one of the most species-rich families in Hymenoptera, with about 1,100 genera and 21,000 valid described species worldwide (Chen and Achterberg, 2019). Within the family, the genus Aleiodes is a large genus of the subfamily Rogadinae, which has 632 described species worldwide (Yu et al., 2016). It is difficult to identify the species of Aleiodes worldwide because of vast species and few descriptions (Quicke et al., 2012). In current, 32 species of the genus Aleiodes have been recorded in the National Species List of South Korea (NIBR, 2020). Compared to the species that have been recorded in the world, the Korean number of Aleiodes species are poorly recognized.

It is known that rogadine wasps parasitize lepidopteran larvae, which are koinobiont-endoparasitic wasp (Zaldívar-Riverón et al., 2008). They are killed and mummified before breeding in the host (Butcher and Quicke, 2011). Species of Aleiodes have been discovered from pastures and vegetable gardens between 2010 and 2014 in Turky (Aydoğdu, 2018), with known hosts as gypsy moths and cutworms (Shaw, 2006). Therefore, they are potential as biological control agents.

In this study, Aleiodes conina is reported for the first time from Korea, which has been originally described in Thailand (Yu et al., 2016). Here, redescription, diagnosis, distribution and illustrations are provided.

Materials and Methods

Aleiodes species 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 van 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.

Aleiodes coninina (Butcher et al., 2012) 종무늬두렁고치벌(신 칭) (Fig. 1A-G)

First and second tergites combined white pattern resembles a bell shape and present dorsal midlongitudinal carina like a rip. For this reason, it was named as follows.
