Diagnosis of female. Length about 2.37 mm, including ovipositor sheath ( Fig. 4A ). Head entirely golden-green except vertex with coppery luster between anterior and posterior ocelli, anterior margin of lower face metallic blue, and scrobal depression slightly bluish-green with bluish luster ( Fig. 4B ); in dorsal view with interocular distance about 0.30-0.50 × as long as head width; vertex meshlike reticulate posteriorly; frons to parascrobal region very finely meshlike coriaceous-reticulate except scrobal depression finely, transversely wrinkled above interantennal region; lower face slightly and longitudinally meshlike coriaceous-reticulate; OOL: POL: LOL: MPOD = 1.5: 2.9: 1.7: 1.0. Antenna dark brown except anellus and apical two-third region of pedicel yellow, and scape with metallic bluish-green luster ( Fig. 4B ). Mesoscutum variably golden-green to greenish-blue with coppery luster; mostly meshlike coriaceous-reticulate except inner side of lateral lobe slightly meshlike sculpture medially. Scutellar-axillar complex similar to mesoscutum in color; with axillae obliquely coriaceous and scutellum meshlike coriaceous to somewhat mesally sculpture on posterior margin. Acropleuron more variable than mesonotum with coppery and slightly purple lusters; meshlike coriaceous-reticulate anteriorly to distinctly meshlike reticulate posteriorly except slightly fine meshlike sculpture medially ( Fig. 4C ). Legs entirely whitish-yellow except mesotibia with dark spot on subbasal region, mesotarsal pegs reddish-brown and tarsomeres dark apically ( Figs. 4 D-E). Gaster entirely smooth to slightly coriaceous. Ovipositor sheaths similar to length of gaster and about twice as long as mv.

Remarks. E. australiensis is a common species in the genus Eupelmus and is widely distributed in the world. Although both sexes of this species are known, we collected only female specimen from Dokdo Island. Therefore, we describe diagnostic characteristics based on female.

When identified insects were classified according to the survey area, a total of five orders, 10 families, and 16 species of insects were observed in East Island and a total of four orders, 15 families, and 15 species were observed in West Island ( Table 2). Among these, 10 species were newly recorded species from Dokdo Island. Specifically, five newly recorded species ( Psammotettix striatus , Eupelmus australiensis , Calliphora nigribarbis , Coelopa frigida , and Pegomya cuniculari s) were distributed on East Island, and eight newly recorded species ( Psammotettix striatus , Brachymeria minuta , Halticoptera circulus , Calliphora nigribarbis , Campiglossa sada , Coelopa frigida , Lucilia illustris , and Scathophaga stercoraria ) were distributed on West Island.

In terms of the taxonomic groups, the species composition of each order, based on the results of monitoring in this survey, were as follows: 6 families and 11 species of Diptera (40.7%), 5 families and 6 species of Hymenoptera and Hemiptera (22.2%), respectively, 3 families and 3 species of Coleoptera (11.1%), 1 family and 1 species of Odonata (3.7%) were identified ( Fig. 3 ).
