description: <i>Geloemyia cockerelli</i> (Malloch, 1930), comb. n. (fig. 5, 13, 38–53) Malloch, 1930: 466; Steyskal, 1977: 42 (<i>Trichempodia</i>). — coquereli: Enderlein, 1942: 109 (<i>Trichempodia</i>) (emendation). M a t e r i a l. <b>Type.</b> Holotype &amp;female;: [<b>Thailand</b>:] “Siam. / top of Doi Satep / 5000 ft., 8.ii.1908 / Alice Mackei / per T.D.A. Cockerell ”, “Pres by Imp. Inst. Ent. / Brit Mus. 1932–143”, “ Trichempodia cockerelli / Type / Det. / J.R. Malloch ”, “Type” [red-bordered circle], “Holotype / Trichempoidia / cockerelli / Malloch / verified by J.E. Chainey, 2002”, “Holotype” [red-bordered circle], “BMNH #252236” (BMNH). <b>Non-type.</b> <b>Malaysia</b>: Malay Peninsula: Selangor, Bukit Kutu, 3,300 ft., 27.09.1932, 1 &amp;female; (H. M. Pendlebury) (ex F. M. S. Museum B. M. 1955–354) (BMNH); Borneo, Mt. Kinabalu, Tenompok-Kundasan, 4.11.1958, 1 &amp;female; (T. C. Maa) (BBM). 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 0.8–1.0× as long as flagellomere 1, face almost vertical, with ventral portions of antennal grooves with slightly protruding calluses, and peristomal cavity longer than eye horizontal diameter, ocellar seta as long as anterior frontal setulae; wing (fig. 42, 49, 50) hyaline, entirely gray microtrichose, with a few pale brown spots along costa vein R 2+3 without stump vein; vein R 4+5 setulose dorsally; crossvein dm-cu strongly oblique, forming angle c. 45° with vein CuA 1; without brownish shade (or at most pale darkened at ends); mesonotum with no presutural and 3–4 postsutural setae (anterior one poorly distinguishable from longer setulae); scutellum with 2 pairs of setae and 0–3 marginal setulae; fore femur with relatively strong postero-dorsal and posteroventral setae; female fore tarsus (fig. 13) with apical tarsomere unmodified, 1.4–1.6 as long as wide, with claw 0.8 times an long as apical fore tarsomere width; female mid femur with unclear femoral organ (larger and sparsely setulose in basal second one-quarter, closer to middle, in the holotype (fig. 44) and small U-shaped bare area in basal one-quarter (fig. 51) in non-type specimens from Malaysia); oviscape almost as long as preabdominal tergites combined, bearing 3–4 moderately thickened, long and curved preapical setae on lateroventral surface (fig. 18) and thinner 3–4 pairs of periapical setae. Wing length 5.2–5.8 mm. Genitalia not dissected. Male unknown. R e m a r k s. This species is very similar to <i>G. cheni</i> sp. n., <i>G. quadriseta</i>, and <i>G. stylata</i>, in all the essential characters, but the synonymy of <i>Geloemyia</i>, <i>Trichempodia</i> and <i>Parageloemyia</i> remained overlooked until the type specimens of the three species were examined and they were found congeneric. The non-type specimens assigned here to <i>G. cockerelli</i> show quite constant differences in the shape and position of the femoral organ, which can be the characters of different species or subspecies, along with minor differences in frons width and wing pattern, but as the material is very limited, I cannot judge if this is not merely a variability of the three characters.
