description: <i>Geloemyia dorsocentralis</i> (Hering, 1940), comb. n. Hering, 1940: 291; Korneyev, 2004: 26; Korneyev, Nartshuk, 2004: 403 (<i>Adapsilia</i>); Soós, 1984: 36 (<i>Adapsila</i>). M a t e r i a l. <b>Type</b>. Holotype &amp;male;: “ Charbin 5.VII / Maoershan / W. Alin”, “Type” [red paper, printed], “ Adapsilia / dorsocentralis /m. Type / det. M. Hering 1940 ” (ZMHB). Paratype &amp;female;: China, Heilongjiang: “ Chandaochezsy / 1.– 10.8.1937 ”, “Mandschukuo”, “ W. Alin ed.”, “ Adapsilia / dorsocentralis &amp;female;. P.

Hering 193-” (MNKB); Russia: S of Primorskiy Kray, Gorno-Tayozhnoe [SE of Ussuriysk], light trap, 20.07.1994, &amp;female; (A. Belov) (SIZK); Kamenushka 45 km SE of Ussuriysk, 29.07.1984, &amp;female; (Shatalkin) (ZMUM). B r i e f r e d e s c r i p t i o n. Eye small, gena 0.8× as high as eye, without subocular spot, twice as high as length of flagellomere 1. Antenna scarcely longer than half face height, flagellomere 1 narrowed towards apex, rounded apically, 1.4× as long as pedicel. Face yellow, with antennal grooves reaching lower 1/4, and rather high, receding epistomal margin. Palpus moderately large, about as long and wide as antenna; labellum moderately developed. All head setae well-developed, except vte 0.3 as long as vti (Korneyev, 2004: fig. 4, <i>1</i>). Thorax orange yellow, except postnotum brown, with 3 dc, 2 pairs of sctl, and well-developed prst sa, prsc ac and kepst) (Korneyev, 2004: fig. 4, <i>4</i>). Prosternum with 4–5 long setulae on each side. Scutellum with 1–3 short setulae on each postero-lateral side. Wing as in fig. 4, <i>2</i>. Costal vein conspicuously reaching apex of M. R 2+3 without spur vein, R 4+5 bare. Crossvein dm-cu 2.1.5–1.7× as long as cell r 4+ 5 in front of it. Coxae without thickened setae, but mid and hind coxae with numerous moderately fine and long black setulae. Femora yellow, setulose, with ventral row setae; fore femur (Korneyev, 2004: fig. 4, <i>3</i>) with 2 rows of postero-dorsal setae in apical half, hind femur with 2 dorsal subapical setae; mid femur without bare area. Abdomen yellow, with moderately long black setulae. Male genitalia (in situ): epandrium oval, with elongate surstyli; proctiger dorsoventrally flattened, apically very slightly lobate, but not split (Korneyev, 2004: fig. 4, <i>5, 6</i>). Oviscape (Korneyev, 2004: fig. 5, <i>1</i>) wide and long, as long as mesonotum and 1.2–1.4× as long as preabdomen, directed postero-ventrally, with ventral apodeme rather short and weakly sclerotized, apical portion of oviscape with ventral lobe moderately wide and short, ending with flat triangular plate (Korneyev, 2004: fig. 5, <i>3</i>), dorsal medial lobe absent, two wrinkled, taenium-like carinae in basal half of dorsal side of eversible membrane (modified taenia?) running into each other medially (Korneyev, 2004: fig. 5, <i>2</i>), paired lateral lobes slightly shorter than ventral lobe, two rasper-like kidneyshaped or irregular-oval sclerites (modified ventral taeniae) between medial and lateral sclerites well separated from each other and oviscape (Korneyev, 2004: fig. 5, <i>1</i>). Aculeus with preapical constriction, as in most species of <i>Geloemyia</i> (Korneyev, 2004: fig. 5, <i>4</i>). Three separate spermathecae, one smaller than other two (Korneyev, 2004: fig. 5, <i>5</i>) Wing length 4.5–5.0 mm. Remarks. This species shares the well-developed prsc sa and additional dorsocentral setae, shape of surstyli and aculeus with other species of <i>Geloemyia</i> and I place it to this genus; it differs from them by 2 or, bare R 4+5 (both characters also in <i>G. wonjuensis</i>) and mid and hind femora setose ventrally, and oviscape strongly widened at base, as in many other Adapsiliina; it is believed to be a basalmost taxon in the genus, quite close to outgroups.
