Abstract

Korean species of Leucospis Fabricius (Hymenoptera: Chalcidoidea: Leucospidae) are reviewed, with one newly-recognized species, Leucospis sinensis Walker, 1860. An identification key to the Korean Leucospis species, diagnoses, biological information and photographs of diagnostic characters are provided in the present study.

    Korea National Arboretum

    Leucospidae is a small and rarely collected family within Chalcidoidea, consisting of 148 species in four genera worldwide: Leucospis Fabricius, 1775; Polistomorpha Westwood, 1839; Micrapion Kriechbaumer, 1894; Neleucospis Bouček, 1974. Among them, the genus Leucospis is the largest genus in the family with 121 species worldwide: fourteen from the Eastern Palearctic and twenty-three from Oriental regions (Ye et al., 2017). Up to date only one species, Leucospis japonica Walker, 1871 has been known from South Korea (Paik, 1978).

    Leucospidae can be easily distinguished from other chalcid families by the following characters: hind femur with one or more teeth; prepectus very narrow; tegula elongate, at least two times as long as broad; forewing longitudinally folded; ovipositor exserted and curved upward over metasoma. Also, most species of the family are known to be ectoparasitoids of solitary aculeate hymenopterans (Noyes, 2016; Ye et al., 2017).

    In the present study, Leucospis sinensis Walker is newly recognized from South Korea. A diagnosis, biological information and photographs of the diagnostic characters are provided.

    Materials and Methods

    The terminology used in the present study follows that of Bouček (1974) and Ye et al. (2017). The images were captured with a Leica DFC 495 camera on a Leica M205A Stereozoom stereomicroscope (Leica, Microsystems, Solms, Germany). The multi-stacked pictures were produced using the LAS software (version 4.1.0., Leica Microsystems, Switzerland). The figure plates were prepared using Adobe Photoshop CS6 (Adobe Systems Incorporated, San Jose, United States of America).

    The following abbreviations are used throughout the text: MS = the shortest distance between base of mandible and lower margin of compound eye; OOL = the shortest distance between posterior ocellus and compound eye; POD = posterior ocellus diameter; POL = the shortest distance between posterior ocelli; T1, T2, etc. = metasomal tergites 1, 2, etc; KNA = Korea National Arboretum; NHMUK = Natural History Museum, London, United Kingdom.

    All examined specimens have been deposited in Korea National Arboretum, Pocheon, South Korea.
