Introduction

Leucospis Fabricius has comparatively large body size to compare with other Chalcidoidea group and peculiar morphology in ovipositor sheath and metasoma structure, like ovipositorial furrow. Also, it has the largest number of species in Leucospidae and is recorded 121 valid species worldwide. Among them, 18 species are recorded in Palaearctic region, but only two species are known from South Korea (Kim et al. 2017; Noyes 2017; Ye et al. 2017).

In South Korea, Leucospis is already recorded by Paik (1974) of Korean entomologist. He recorded Leucospis japonica Walker by Korean Chalcidoidea checklist. After this, recently, Leucospis sinensis Walker was reported by Kim et al. (2017).

In this study, L. yasumatsui Habu, which is the third species of South Korean Leucospis, is reported for the first time.

Materials and Method

Specimen used in this study are deposited in the Laboratory of Animal Systematics, Yeungnam University (YNU, Gyeongsan, Korea). Morphological terms and ab- breviations follow Bou ek (1974).

Specimen was examined with a stereomicroscope of LOMO and photographed with an AxioCam MRc5 camera and Plan Apo S 1.5× FWD 30 mm objective lens attached to a SteREO Discovery V20 stereomicroscope (Zeiss, Germany).

Serial images were combined using Extended Focus program of AxioVision SE64 software and digitally retouched using Adobe Photoshop CS6 for clarify.

Leucospis Fabricius, 1775: 361. Type species: Leucospis dorsigera Fabricius, 1775.

Key to the South Korean Leucospis Fabricius

1. Pronotum with two distinct yellow bands. Hind femur with four long and slender teeth. Ovipositor sheath distinctly shorter than metasoma, reaching about 0.8× length of T5

··· L. sinensis Walker - Pronotum with one yellow band or with two yellow bands of different length. Hind femur (Fig. 1D) with 12–14 small teeth ventrally. Ovipositor sheath (Fig. 1C) distinctly reaching anterior margin of T1···2 2. Scape usually yellow with dark spot dorsobasally. T1 with two ovipositorial furrow. Ovipositor sheath reaching at least posterior margin of scutellum. Hind femur with yellowish lunate band on basal region marginally

···L. japonica Walker - Scape (Fig. 1B) black with brownish spot on extreme

basal region. T1 (Fig. 1C) with one ovipositorial furrow.

Ovipositor sheath (Fig. 1C) at most reaching posterior margin of propodeum. Hind femur (Fig. 1D) with yellowish spot on basal region submarginally··· L. yasumatsui Habu

Leucospis yasumatsui Habu, 1961 꼬마밑들이벌(신칭) (Figs. 1A–D)

Leucospis yasumatsui Habu, 1961: 83. Holotype: ♀. Type Locality: China. Type depository: KYUN.

Diagnosis. Female (habitus: Fig. 1A). Length = 8.62 mm.

Head (Fig. 1A) width about 1.4x head high; with vertex punctate to lower face longitudinally reticulate; OOL: POL:

LOL: MPOD = 2.0: 3.5: 1.3: 1.0. Mesosoma mostly punctate except mesopleural depression smooth medially to rugulose laterally; pronotum with inconspicuous discal carina and distinct admarginal carina. Metasoma mostly punctate with single ovipositorial furrow on T1. T1 (Fig. 1C) with one ovipositorial furrow. Ovipositor sheath slightly longer than metasoma, at most reaching posterior margin of propodeum.

Color. Scape (Fig. 1B) black with brownish spot on extreme basal region. Body mostly black with yellow bands on pronotum, scutellum, anterior of T1, medial of T4 and posterior of T5. Fore leg mostly black except knee, tibia dorsolongitudinally and apical four tarsus brownish. Middle

leg similar to front leg in color. Hind leg black with yellow spot on subbasal and apical region of femur (Fig. 1D) and dorsoapical region of tibia, but trochanter, trochantellus, knee, and tarsus brown.

Material examined. [South Korea] 1 female, Gangwon- do, Pyeongchang-gun, Jinbu-myeon, Mapyeong-ri, 30.vi.1985, S.Y. Lee (YNU).

Biology. Unknown.

Distribution. South Korea (new record), China, Russia.

Variations. In comparison to holotype of L. yasumatsui (photographs in Ye et al., 2017), the specimen of L.

yasumatsui is slightly different in body color and color patterns of hind femur. Body color of holotype is primarily black with dark brown luster and hind femur of holotype has not yellow spot on basal region. But, our specimen is mostly more black color than holotype and hind femur has distinctly yellow spot on basal region.
