Abstract

We report ten ichneumonids species new to South Korea. These species belong to eight subfamilies, Acaenitinae Forster, 1869, Diacritinae Townes, 1965, Ichneumoninae Latreille, 1802, Mesochorinae F$\ddot{o}$rster, 1869, Microleptinae Townes, 1958, Pimplinae Wesmael, 1845, Tryponinae Shuckard, 1840, and Xoridinae Shuckard, 1840. Photographs of the habitus and diagnosis of ten newly recorded species, as well as host information are provided.

Keywords

INTRODUCTION

The family Ichneumonidae Latreille, 1802 is a small to large-sized family containing 24,281 described species within 1,579 genera worldwide. Of these, 540 species have been recorded from South Korea (Yu et al., 2012). Most ichneumonids are endo-ectoparasitoids of Lepidoptera, Coleoptera, Hymenoptera, Diptera or Arachnida. Therefore, ichneumon flies are important to control of reproduction of injurious insects (Bartlett et al., 1978). Known species number and biological information of ichneumonid subfamilies and genera treated in this study are summarized in Table 1.

Digital images of habitus and diagnoses of ten newly recorded species from Korea are provided, along with available host information

 

MATERIALS AND METHODS

Materials used in this study were collected with insect sweeping nets and Malaise traps, then deposited in the animal systematic laboratory of Yeungnam University (YNU, Gyeongsan, Korea). Specimens were examined with an AxioCam MRc5 camera attached to a stereomicroscope (Zeiss SteREO Discovery, V20; Carl Zeiss, Göttingen, Germany), processed using the AxioVision SE64 software (Carl Zeiss), and optimized with a Delta imaging system (i-solution; IMT i-Solution Inc., Vancouver, Canada). The morphological terminology mostly follows that of Townes (1969). Abbreviations were as follows: TD, type depository; DEI, Deutsches Entomologisches Institut, Schicklerstrasse 5, D-16225 Eberswalde, Germany; HU, Entomological Institute, Faculty of Agriculture, Hokkaido University, Sapporo, Japan; LS, Linnaean Society, Burlington House, Piccadilly, London, England, United Kingdom; MOMOI, Kobe University, Faculty of Agriculture, Entomological Laboratory, Kobe, Japan.
