Milichiella plaumanni
Differs from congeners in the combination of brown microtomentose ocellar triangle, basoflagellomere basomedially red, posterior eye margin with narrow notch, and male T2-5 silvery microtomentose except for black tip of T5.
Male coloration and vestiture: frons brown, ocellar triangle and orbital plates brown microtomentose, lunule brown, basoflagellomere basomedially red, face greyish microtomentose, palpus black; thorax with mesonotum brown microtomentose, scutellum same, pleura slightly more greyish microtomentose, wing hyaline, veins brown, brown spot at tip of vein R1 absent, calypter brown, hairs white, halter black, legs black; abdomen with T2-5 silvery white microtomentose except for black tip and posterolateral corners of T5.
Morphology. Head: frons with 2 orbital and 2 frontal setae, anterior frontal seta very slightly medioreclinate. In males frons 1.7x as wide at posterior margin than at base of antenna, arista about 5.0x as long as basoflagellomere wide, pubescence on arista very short, posterior eye margin with notch (3oc) and emargination (1.5).
Thorax: 2 dc, 1 prsc, 1 pprn, 1 prs, 2 keps setae, posterior prsc less than 0.8x as long as posterior dc, seta between posterior prsc and posterior dc absent. Wing with vein R4+5 and M1 weakly converging (1.6), and ultimate section of vein M1 3.2x as long as penultimate section. Fore femur normal setulose, tibial organ absent.
Male abdomen: posteromedial triangular projection of T1 into T2 weak. Tergal chaetotaxy: T2 anterolateral corner with single line of setae, T2-4 posterior margin with 1 row of setulae. S5 as long as wide, 1.6x as long and 2.7x as wide as S4, V-shaped with posterior indention reaching to middle of sternite, setulose. Male genitalia with apical seta on cercus longer than epandrial setae, 1 seta on subepandrial plate, surstylus 1.2x as long as epandrium high, bent posteriorly, dilated apically (2.4x), 9.2x as long as wide, structure of lateral surface smooth, medial surface with some small setulae preapically near anterior margin and in middle.
Body length: 3.0 mm; wing length: 2.7 mm.
