A New Record of Parasitoid Wasp Schizoprymnus terebralis (Hymenoptera: Braconidae) from Korea

The family Braconidae (Hymenoptera) are worldwide in distribution with approximately 20,000 described species (Yu et al., 2016), in which 400 species were subdivided into the subfamily Helconinae (Yu et al., 2006). Most of the helconid wasps are solitary koinobiont endo-parasitic to beetle larvae (Beyarslan and Coban, 2014). Members of the genus Schizoprymnus (Förster, 1862) are characterized by anterior three metasomal tergites fused to form a carapace, of which remaining segments are hidden (Belokobylskij and Maeto, 2007). In current, the genus includes 8 species of Schizoprymnus acataphractus Snoflák, 1953, Schizoprymnus azerbajdzhanlcus Abdinbekova, 1967, Schizoprymnus cavernus Papp, 1989,

Schizoprymnus commotus Papp, 1989, Schizoprymnus nigripes Thomson, 1892, Schizoprymnus opacus Thomson, 1892, Schizoprymnus querculus Papp, 1989 and Schizoprymnus temporalis Tobias, 1966 (NIBR, 2018).

In this study, Schizoprymnus terebralis (Snoflák, 1953) is reported for the first time in South Korea. Rediscription, diagnosis, host information and illustrations are provided.

Materials and Methods

Materials of the braconids were collected by netting, sweeping and trap, which were preserved in 80% ethyl alcohol.

Taxonomic information is referred from Yu et al. (2016).

Terminology used for morphological characters follow Sharkey and Wharton (1997). Photographs were taken using
