Two new records of Chalcididae (Hymenoptera, Chalcidoidea) from Korea
The Chalcididae belong to a medium-sized family of parasitoids in the superfamily Chalcidoidea (Hymenoptera). Chalcidids can be recognized by the swollen hind femur, the indistinct prepectus, the sharp occipital carina bordering the gena posteriorly, and the strong punctation of the mesosoma. They have been recorded parasitizing six insect orders, and several species are facultative or obligate hyperparasitoids. More than 1,500 species in 90 genera have been recorded worldwide, of which 12 species in six genera have been recorded in South Korea. As a result of taxonomic and faunal studies on Korean Chalcididae, we have found two newly recorded species, Haltichella nipponensis Habu and Dirhinus anthracia Walker, in Korea. These species were discovered using Malaise traps, Lindgren funnel traps, and observation with the naked eye in Jeonbuk, Gangwon province, and Sejong city in 2023. The genus Haltichella Spinola, 1811, is recorded in Korea for the first time. In this presentation, we provide morphological and ecological information on these species.
