 Abstract

 Five species of the genus Streblocera (Hymenoptera: Braconidae: Euphorinae) are reported for the first time from Korea: Streblocera (Eutanycerus) affinis Belokobylskij, Streblocera (E.) galinae Belokobylskij, Streblocera (E.) lienhuachihensis Chou, Streblocera (E.) major Belokobylskij, and Streblocera (Streblocera) spasskensisBelokobylskij. Diagnosis and photographs for the species are provided.

    • Introduction

    The genus Streblocera is characterized by the raptorial antenna of the female, probably an adaptation to grasping the host (Shaw, 1985 and Chou, 1990). This genus has 98 species recorded throughout the world, including 26 species in the East Palaearctic fauna (Yu et al 2012).
    Belokobylskij (1987) divided Streblocera Westwood into three subgenera: Aisastreblocera Belokobylskij, Cosmophoridia Hedqvist, and Streblocera Westwood. Chen and van Achterberg (1997) reassessed the subgeneric division into five subgenera: Aisastreblocera Belokobylskij, Cosmophoridia Hedqvist, EutanycerusFoerster, Villocera Chen and van Achterberg, and Streblocera Westwood. Belokobylskij (2000b) agrees with the establishment of Cosmophoridia and Eutanycerus, but Villocera Chen and van Achterberg, a junior synonym of Eutanycerus Foerster. We followed the taxonomic treatment by Belokobylskij (2000b)in this paper.
    The host of Streblocera is almost unknown, except for only two species: Streblocera okadai Watanabe, known as a solitary endoparasitoid of Galerucinae, and Medythia nigrobilineata (Motschulsky; Chrysomelidae), its mature larva emerge from the adult of the host (Watanabe, 1942, Maeto and Nagai, 1985 and Chen and van Achterberg, 1997). Also, Streblocera fulviceps is a parasitoid of Chaetocnema cilindrica Baly (Chrysomelidae; He, 1984 and Chen and van Achterberg, 1997).
    To date 10 species of Streblocera in Korea are known (Papp, 1985, Ku, 1997 and Belokobylskij and Ku, 1998; Ku et al 2001). In this study, five species of Strebloceraare reported for the first time from Korea. We provide a diagnosis and photographs for the species.

    Materials and methods

    All examined materials are deposited in the Science Museum of Natural Enemies (SMNE), Geochang, Korea. The specimens were photographed with Leica DMS 1000 using the Leica Application Suite (Leica Camera; Aktiengesellschaft, Wetzlar, Germany). Terminology used in this paper follows that of van Achterberg (1993). Abbreviations used in this study are as follows: LT, light trap; MT, malaise trap.
