The genus Centistes comprise 68 species worldwide (except for the Australian region), including 40 species in the Eastern Palaearctic fauna (Rousse and Braet, 2012; Yu et al., 2012). According to van Achterberg (1985), Centistes was divided into four subgenera: CentistesHaliday, 1835, SyrrhizusFörster, 1862, AncylocentrusFörster, 1862, and Anartionyx van Achterberg, 1985. Shaw (1985) disagreed with the use of these subgeneric divisions. Belokobylskij (1992) reported that Syrrhizus is an independent genus due to lacking of a medial vein and agreed with the position of the remaining three subgenera of Centistes. Belokobylskij (2000c) suggested that the subgenus Chaetocentistes Belokobylskij, 2000. We followed van Achterberg (1985) in this paper.
All Centistes species are solitary koinobiont endoparasitoids of Coleopteran adults, particularly the families Curculionidae, Chrysomelidae, Coccinellidae, Anthicidae, and Carabidae (Loan, 1972; Shaw, 1985; Chen and van Achterberg, 1997).
Previously, seven Korean Centistes species were recorded by Papp (1994) and Ku et al. (2001). In this study, seven Centistes species are reported as new to Korea. We provide their diagnosis, distribution, host information, and photographs.
Materials and Methods
All examined materials were deposited in the Science Museum of Natural Enemies (SMNE), Geochang, Korea. The specimens were photographed with Leica DMS 1000 using the Leica Application Suite (LAS). Terminology used in this paper follows that of van Achterberg (1993). Abbreviations used in the present study are as follows: CB-Prov. Chungbuk, CN-Prov. Chungnam, GB-Prov. Gyeongbuk, GG-Prov. Gyeonggi, GW-Prov. Gangwon, JN-Prov. Jeonnam, LT-Light trap, MT-Malaise trap.
