description: <i>Geloemyia quadriseta</i> Hendel, 1933 (fig. 8–10, 16, 21, 67–76) <i>quadriseta</i> Hendel 1933: 13 (<i>Geloemyia</i>); Hendel, 1934: 142; Soós, 1984: 38; Korneyev, 2004: 43; Korneyev, Nartshuk, 2004: 408; Nartshuk, Korneyev, 2005: 9 (<i>Parageloemyia</i>). — <i>ornata</i> Hering, 1940: 293 (<i>Parageloemyia</i>); Enderlein, 1942: 111; Soós, 1984: 37 (<i>Dicranostira</i>), <b>syn. n.</b> — <i>nigrofasciata</i> (<i>Geloemyia</i>); Hendel 1933: 13; Soós, 1984: 37; Korneyev, 2004: 43; Korneyev, Narchuk, 2004: 408 (<i>Parageloemyia</i>), <b>possible synonym</b>. M a t e r i a l. <b>Type.</b> Syntype &amp;female; <i>Geloemyia quadriseta</i>: [<b>China</b>:] “Shin Kai Si / Mt. Omei / Szechuen China ”, “ 1000 feet / alt”, “DCGraham / collector”, “ Geloemyia / quadrisetosa [sic!] / Hend. Hend. [det.]” (red paper rectangle) (USNM). Holotype &amp;female; <i>Parageloemyia ornata</i>: [<b>China</b>:] “Chandaoche / Manchukuo, VIII. 1938 / W Alin”, “Type”, “ Parageloemyia ornata m. Type &amp;female; / Hering det.” (MNKB). Holotype &amp;male; <i>Geloemyia nigrofasciata</i>: “ Suifu / Szechuen / China ”, “ DC Graham / coll.”, “Type No / 41873 / U.S.N.M.” (red paper rectangle), “ Geloemyia / nigrofasciata / Hend.” (USNM). <b>Non-type.</b> <b>Japan</b>: Tokyo, 11.05.1910, 1 &amp;female; (E. Galois) (MHNP). B r i e f r e d e s c r i p t i o n. This species can be recognized from combination of the head with narrow parafacial dorsally approximately as long as flagellomere 1 width, face slightly receding, with ventral portions of antennal grooves slightly protruding, and peristomal cavity nearly as long as eye horizontal diameter, ocellar seta as long as anterior frontal setulae; wing gray microtrichose, with a variously developed brown pattern consisting of the short subbasal crossband posterior of costal cell apex and a spot at base of cell cua1, pterostigmal crossband, from the apical half of stigma through crossvein r-m to posterior wing margin, short accessory crossband in cell r1 distal of vein R 1 apex, preapical crossband (from cell r1 through dm-cu) either broken at vein M or complete, and apical band usually with extensions into cell r 2+3 or along vein M; vein R 2+3 without stump vein; vein R 4+5 setulose dorsally; crossvein dm-cu moderately oblique, forming angle c. 60–70° with vein CuA 1; variously brownish shaded (narrowly in <i>G. quadriseta</i> holotype and broadly in <i>P. ornata</i> syntypes); mesonotum with no presutural and 3 postsutural dorsocentral setae; scutellum with 2 pairs of setae and no marginal setulae; female fore tarsus with unmodified trapezoid preapical, and strongly modified apical tarsomere 0.8× as long as wide, bearing thumb-like, long setulose lateral process, with claw 0.4–0.5 times an long as apical fore tarsomere width; female mid femur without femoral organ; oviscape almost as long as preabdominal tergites combined, its apex ventrally with pair of rows consisting of 3 shorter and one long apical setae (fig. 16). R e m a r k s. Study of holotype females of <i>Geloemyia quadriseta</i> and <i>Parageloemyia ornata</i> shows them to have similarly modified fore tarsomere and no femoral organ; I therefore consider them conspecific and synonymize these names. As the wing pattern of <i>Geloemyia cheni</i> and <i>G. trifasciata</i> is sexually dimorphic, with darker, wider and solid crossbands in males, it can be interpolated on other species, including <i>G. quadriseta</i> (but except <i>G. namibica</i> and <i>G. wonjuensis</i>). Description of <i>G. nigrofasciata</i> was based on a single male, which shows no characters differing closely related <i>G. cheni</i> and <i>G. quadriseta</i> and thus cannot be formally proven to belong either to the first or to the second species. Type localities of <i>G. quadriseta</i> based on females and of <i>G. nigropunctata</i> based on male are in Sichuan Province c. 200 km from each other, and this is quite a reason that they could be conspecific. I leave the formal synonymization pending until more rigorous proofs are found.
