Korean J. Syst. Zool. Vol. 25, No. 1: 99-106, March 2009 Taxonomic Review of the Tribe Campsomerini (Scoliinae, Scoliidae, Hymenoptera) in Korea Jeong Kyu Kim* Department of Biological Sciences, Faculty of Science, Hanseo University, Chungcheongnam-do, 356-706 Korea ABSTRACT Six Korean species of the tribe Campsomerini are taxonomically reviewed: Campsomeriella annulata, Megacampsomeris grossa matsumurai, M. prismatica, M. uchidai, M. schulthessi, M. stoetzneri. Of these, M. grossa matsumurai and M. stoetzneri are new to Korea. A key to Korean genera and species, diagnostic characteristics and digital images are also provided.

Campsomerini is one of two tribes of the subfamily Scoliinae including another tribe Scoliini. Korean species of Campsomerini are easily distinguished from Scoliini by the SYSTEMATIC ACCOUNTS presence of two submarginal cells and two recurrent veins (of which second recurrent vein always running from sub- Order Hymenoptera 1 discoidal to cubital vein) in forewing (Fig. 1A). *Family Scoliidae 2 Up to date, four species of Campsomerini have been *Subfamily Scoliinae 3 known from Korea (Betrem, 1928, 1941; Uhida, 1933, 1936; *Tribe Campsomerini Kim, 1970, 1980; Tsuneki, 1972; Lelej, 1995; Gupta and Jonathan, 2003; Terayama and Nagase, 2007).
