Abstract :Two species, Euurobracon breviterebrae Watanabe and Helconidea nipponica (Watanabe), of the family Braconidae are recorded from South Korea for the first time. Digital images and diagnoses of these newly recorded species are provided. One of them, male of H. nipponica (Watanabe) was hitherto unknown and is first described here.

The family Braconidae is a very large group with a worldwide distribution, containing more than 21,000 species (Yu et al. 2016). Among these, 4,800 species are already known from the Eastern Palearctic region. Here, we report two unrecorded species from two small genera, Euurobracon (subfamily Braconinae) and Helconidea (subfamily Helconinae), consisting of 12 and 15 species, respectively. So far one species of the genus Euurobracon, Euurobracon yokahamae (Dalla Torre, 1898), has been recorded from South Korea by Matsumura, 1931. This genus is very distinct in Subfamily Braconinae by the nervulus of the fore wing being strongly postfurcal and by the structure of the eye which are very different in both sexes (female’s eye very smaller than male’s one). On the other hand, in the genus Helconidea, three species have been recorded from South Korea until now. This genus easily distinguished from Subfamily Helconinae by presence of ventral tooth in hind femur; occipital carina connected with hypostomal carina distinctly above lever of base of mandible. These two genera were known as koinobiont endo-parasitoids of coleopteran larvae, mainly Cerambycidae.
This work aims to provide a taxonomic account of the
unrecorded species of the Braconidae from South Korea with first description of a male of H. nipponica.
Materials and Methods
Materials used in this study were collected by sweep net and Malaise traps, after which they were deposited in the Animal Systematic Laboratory of Yeungnam University (YNU, Gyeongsan, South Korea). Distributional data mainly follow that of Yu et al. (2016). Collection localities of provinces in South Korea are abbreviated as follows: CN, Chungcheongnamdo; GB, Gyeongsangbuk-do; GG, Gyeonggi- do; GN, Gyeongsangnam-do; JB, Jeollabuk-do; JN, Jeollanam- do. Other abbreviations used in this paper as follows: HU, Hokkaido University, Faculty of Agriculture, Entomological Institute, Sapporo, Japan; TS, Type species; TD, Type depository; TL, Type locality.
Specimens were examined using an AxioCam MRc5 camera attached to a stereo microscope (Zeiss SteREO Discovery. V20; Carl Zeiss, Göttingen, Germany), processed using AxioVision SE64 software (Carl Zeiss), and optimized with a Delta imaging system (i-solution, IMT i-Solution Inc.
Vancouver, Canada).

Remark. Only two species of this genus are in South Korea, these species are easily distinguished by promotion of ovipositor and radius; ovipositor in E. yokohamae is 6.5-8 times longer than body, radius of the hind wing inserted at the upper end of the basal nervure while in E. breviterebrae it is shorter than body and radius of the hind wing inserted at the upper sixth of the basal nervure.
