description: <i>Geloemyia cheni</i> Kim, Han &amp; Korneyev, sp. n.

Paratypes: <b>Korea</b>: 2 &amp;female;, labels as in the holotype (NHMG); 1 &amp;male;, 1 &amp;female;: Gangweon-do, Weonju-si, Maeji-ri, Yonsei Univ. campus, black+ mercury vapor light trap, 12.06.2000 (S.-K. Kim); 1 &amp;female;: Gyeongsandam-do, Geoje-si, Dongbu-myeon, Mt. Noja, mercury light trap, 4.06.1997, 70 % EtOH to chloroform (D. S. Gu); 1 &amp;female;: Seoul, Jung-gu, Mt. Hamsan, Seoul tower, 3.06.2001 (H.-W. Byun) (SIZK); other specimens listed by Kim &amp; Han (2001) as “ <i>Parageloemyia nigrofasciata</i> ” are also paratypes. D i a g n o s i s. This species can be readily distinguished from other species of the genus <i>Geloemyia</i> by the following combination of characters: 1 or, face with epistome 0.3× as high as antennal grooves, the latter entirely fused, vein R 4+5 setulose, female fore tarsus with tarsomeres 4 and 5 widened in female; mid femur with femoral organ in female.

Thorax (fig. 21, 31, 32) reddish yellow to brownish yellow with brown to reddishbrown pattern; postpronotal lobe pale yellow to brownish yellow with 1 seta and 4–8 setulae; scutum with 1 presutural supra-alar, 1 scapular seta (scap), 3 postsutural dc, and 1 prst ac seta, and also 1 postsutural supra-alar, 1 intra-alar, 1 postalar and 2 notopleural setae; round dark brown spot ventral of postsutural supra-alar seta; mesonotum with brown or reddish brown lyrate pattern at incertions of dorso-ventral muscles; scutellum pale yellow to brownish yellow, bare; apical scutellar seta 1.8–2.9×, basal scutellar seta 1.6–2.5× as long as scutellum; pleura (fig. 23, 32; Kim, Han, 2001: Fig. 14G) pale yellow to reddish yellow; proepisternum with 2–7 setae; 1 anepisternal seta and 2–4 long setulae and relatively short setulae in posterior part of anepisternum; 1 katepisternal, 1 anepimeral seta; katepimeron pale yellow to reddish yellow; mediotergite brown. Legs (fig. 23, 24) pale yellow to brownish yellow; fore coxa as on fig. 33; fore trochanter unmodified, with 3 fine setulae; fore femur brownish yellow with erect setulae, posterodorsally with 3 dorsal setae, postero-ventrally with 4–6 setae shorter than postero-dorsal ones; female fore tarsus modified: tarsomeres 3–5 in female modified: tarsomere 3 wide, 1.5× as wide as tarsomere 2; tarsomere 4 enlarged and asymmetrical, anterior half flattened, short and sparsely setulose on dorsal surface, tarsomere 5 smaller than tarsomere 4, with 6–7 long setulae on anterior margin longer than claws; male fore tarsus unmodified; mid coxa and trochanter unmodified, as on fig. 34; mid femur with short dense setulae, anterodorsally in medial part with large oval femoral organ, almost half as long as femur, and not concave; hind femur with 2–5 apicodorsal setae and long antero-ventral setulae. Wing of female hyaline with extensive brown banded pattern (fig. 27; Kim, Han, 2001: Fig. 14G); wing bands broader and darker in males; humeral break present, subcostal break almost inconspicuous; Sc incomplete at C; cells bm and cu <i>p</i> covered with microtrichia; vein R 4+5 setulose dorsally; halter yellow. Wing of male with wide crossbands, similarly to those in <i>G. nigrofasciata</i> holotype (as on fig. 73), but differing in subapical crossband often broken on vein M. Male abdomen (Kim, Han, 2001: Figs 14C, D) yellowish brown, densely setulose, laterally long setulose; syntergite 1+2 1.8× as long as tergites 3–4 combined; tergite 5 0.64– 0.7× as long as syntergite 1+2; sternites 3–4 subquadrate. Female abdomen (figs 35–37) reddish yellow to brownish yellow; syntergite 1+2 1.54– 2.35× as long as tergites 3–6 combined; tergites 5–6 short, sometimes hidden in dorsal view; sternites 1+2 and 6 trapezoid, sternites 3–5 subrectangular. Male genitalia (Kim, Han, 2001: Figs 15 E-H): epandrium dorsally bare, with few laterodorsal setulae; cerci with relatively short sparse setulae; surstylus distinctly protruding postero-ventrally. Female terminalia: oviscape tapering towards apex (Kim, Han, 2001: Fig. 15A) brownish yellow, in apical one-fifth or one-sixth dark brown, with pair of ventrolateral rows of 5–6 slightly thickened and elongated setulae, laterally and dorsally with suberect, unmodified setulae; 1.59–2× as long as preabdominal tergites combined and 1.05–1.1 times as long as thorax; apex black with 3–4 pairs fairly long and stout setae ventrally (fig. 37); aculeus barbed, with conspicuous subapical constriction (Kim, Han, 2001: Fig. 15B); 3 smooth oval spermathecae (Kim, Han, 2001: Fig. 15C); egg (Kim, Han, 2001: Fig. 15D) oblanceolate in outline. Wing length &amp;male;: 5.8, &amp;female; 6.4 –6.8 R e m a r k s. As was noted by Hering (1940) and then by Korneyev (2004), Hendel confused the figures of <i>G. quadriseta</i> and <i>G. nigropunctata</i> wings that was resulted in further misidentifications. A female from “Kirin: Kao-lin-tze, 20.VII.1940 … in Museum Heude” identified by Chen (1947: 55) as “ <i>Parageloemyia nigrofasciata</i> ” and depicted (Chen, 1947: Figs 8, 10) clearly belongs here.
