Dacnusa (Pachysema) luctuosa sp. n. : 88 = head in dorsal view, 89 = head in lateral view, 90 = mandible, 91 = ventral half of mesopleuron with precoxal suture, 92 = hind femur with indication of its sculpture, 93 = distal part of right fore wing, 94 = first subdiscal cell of fore wing, 95 = tergites 1–3 with indication of the sculpture of first tergite. – 96–99. Dacnusa (Pachysema) arkadii TOBIAS : 96 = head in dorsal view, 97 = distal part of right fore wing, 98 = ven- tral half of mesopleuron with precoxal suture, 99 = tergites 1–3 Mesopleuron also polished, precoxal suture wide, not reaching fore margin of mesopleuron, rugulose ( Fig. 91 ). Propodeum and metapleuron above and below densely rugulose with rugose element, metapleuron medially polished; propodeum and metapleuron less hairy. – Hind femur 4.1 times as long as broad distally, its outer side with disperse hairpunctures ( Fig. 92 ). Hind tibia as long as hind tarsus; hind basitarsus as long as tarsomeres 2–4 combined. Fore wing somewhat longer than body. Pterostigma ( Fig. 93 ) cuneiform, parallel-sided and nearly 13 times as long as wide, issuing r near from its base, r slightly longer than width of pterostigma, 2–SR 2.8 times length of r ; 3–SR + SR1 bent and ending far before tip of wing; 1–R1 0.6 times as long as pterostigma. Vein m–cu clearly antefurcal ( Fig. 93 ). Outer-lower side of subdiscal cell closed, i.e. veins 3CU1 + CU1b present, CU1a issuing clearly posteriorly ( Fig. 94 , see arrows). First tergite ( Fig. 95 ) evenly broadening posterioly, 1.4 times as long as broad behind, pair of spiracles at middle of tergite, pair of less converging and less distinct keels merging medially into rugo-rugulosity. Tergites 2–3 fused and as long as first tergite, together with further tergites polished. A dark coloured species. Scape and pedicel black with weak rusty tint; flagellum blackish. Head, mesosoma and first tergite black, metasoma dark brown. Mandible brownish yellow, oral parts pale yellow. Tegula dark brown, parategula brown. Coxae dark brown, trochanters yellow, fore femur basally, femora 2–3 entirely brown, tibiae 2–3 distally and tarsi 1–3 brown to light brown, rest of legs yellow to yellowish. Wings hyaline, pterostigma and veins brownish. Female and host unknown. Distribution: Korea . The new species, Dacnusa (Pachysema) luctuosa , runs to D. (P.) arkadii TOBIAS with the help of TOBIAS’ s key (1998: 324–354): mesoscutum less hairy, precoxal suture distinct, notaulix present on fore third of mesoscutum; however, the two species are separated clearly by the features keyed: 1 (2) Temple in dorsal view not bulged, i.e. head between temples and eyes equally broad; head twice as broad as long ( Fig. 96 ). Vein r 2.8 times as long as width of pterostigma, 2–SR 0.7 times length of r ( Fig. 97 ). Hind tibia longer than tarsus. Precoxal suture finely crenulate ( Fig. 98 ). Antenna with 26–28 antennomeres, middle flagellomeres 2.2–2.3 times as long as broad. First tergite somewhat broader in general, 1.25 times as long as broad behind, finely sculptured ( Fig. 99 ). Legs yellow or brownish. ♂: 1.7–2.2 mm . – Asiatic Russia (Kuril Islands) D. (P.) arkadii TOBIAS, 1997 2 (1) Temple in dorsal view bulged, i.e. head between temples slightly broader than between eyes; head 1.8 times as broad as long ( Fig. 88 ). Vein r a bit longer than width of pterostigma, 2–SR 2.8 times length of r ( Fig. 93 ). Hind tibia and tarsus equal in length. Precoxal suture rugulose ( Fig. 91 ). Antenna with 22 antennomeres, middle flagellomeres 1.9–1.8 times as long as broad. First tergite somewhat less broad in general, 1.35 times as long as broad behind, rugo-rugulose ( Fig. 95 ). Legs dark brown to brown with less yellow pattern. ♂: 1.8 mm . – Korea D. (P.) luctuosa sp. n. The new species is related to D. (P.) fraterna TOBIAS considering their similar features like D. (P.) arkadii , the two species are discriminated as follows: 1 (2) Hind tarsus shorter than hind tibia. Temple in dorsal view not bulged, i.e. head between eyes and temples equally broad. Antenna with more than 25 antennomeres (quotation after TOBIAS 1998: 341 ). Middle tooth of mandible pointed. Legs brownish yellow. ♂: 1.7 mm . – Asiatic Russia ( Maritime Territory) D. (P.) fraterna TOBIAS, 1998 2 (1) Hind tarsus and tibia of equal length. Temple in dorsal view slightly bulged, i.e. head between temples slightly broader than between eyes ( Fig. 88 ). An- tenna with 22 antennomeres. Middle tooth of mandible less pointed ( Fig. 90 ). Legs dark brown to brown with less yellow pattern. ♂: 1.8 mm . – Korea D. (P.) luctuosa sp. n.
