Milichiella multisetae
Differs from congeners in the combination of subshiny black frons, brown microtomentose male T2, and red brown microtomentose T3-5 except for brown tip and lateral sides of T5.
Male coloration and vestiture: frons subshiny black, ocellar triangle and orbital plates brown microtomentose, lunule brown, basoflagellomere black, face grey microtomentose, palpus black; thorax with mesonotum brown microtomentose, scutellum and pleura same except for big shiny spot on an- and katepisternum, wing anterior margin apical of sc brown, brown spot at tip of vein R1 weak, calypter hyaline with brown margin, halter black, legs black; abdomen with T2 brown microtomentose, T3-5 red brown microtomentose except for brown tip and lateral sides of T5.
Morphology. Head: frons with 2 orbital and 2 frontal setae, anterior frontal seta medioclinate. In males frons 1.9x as wide at posterior margin than at base of antenna, arista about 5.7x as long as basoflagellomere wide, pubescence on arista very short, posterior eye margin with notch (5oc) and slight emargination (1oc).
Thorax: 3+1 dc, 1 prsc, 1 pprn, 1+0.8+0.6 prs, 2+0.8+0.7 keps setae, posterior prsc about as long as posterior dc, seta between posterior prsc and posterior dc present. Wing with vein R4+5 and M1 weakly converging (1.6), and ultimate section of vein M1 1.9x as long as penultimate section. Fore femur slightly stronger setulose, tibial organ absent.
Male abdomen: posteromedial triangular projection of T1 into T2 present. Tergal chaetotaxy: T2 anterolateral corner with more than 3 lines of setae, T2-5 posterior half setulose. S5 1.2x as long as wide, 1.5x as long and 2.1x as wide as S4, extremely setulose. Male genitalia with apical seta on cercus as long or longer than epandrial setae, cercus strongly setulose, 1 seta on subepandrial plate, surstylus 1.2x as long as epandrium high, slightly bent posteriorly, slightly dilated apically (1.2x), 7.8x as long as wide, posteroapical margin slightly serrate, structure of lateral surface smooth, medial surface with long setulae along anterior margin.
Body length: 4.7 mm; wing length: 4.8 mm.
