Milichiella griseomacula
Differs from congeners in the combination of posteromedial grey spot on the mesonotum, 2 dc, and abdominal colour pattern.
Male coloration and vestiture: frons brown, ocellar triangle and orbital plates brown microtomentose, lunule ?, basoflagellomere basomedially yellow, face greyish microtomentose, palpus ?; thorax with mesonotum brown microtomentose except for grey posteromedial spot between dc, scutellum and pleura brown microtomentose, wing hyaline, veins brown, brown spot at tip of vein R1 absent, calypter brown, halter black, legs black; abdomen with T2-5 silvery microtomentose except for brown microtomentose anterior margin of T2, posteromedial spot on T2 and posterior 3/4 of T5.
Morphology. Head: frons with 2+0.5 orbital and 2 frontal setae, anterior frontal seta very slightly medioreclinate. In males frons 2.0x as wide at posterior margin than at base of antenna, arista about 6.0x as long as basoflagellomere wide, pubescence on arista slightly longer than base of arista wide, posterior eye margin with narrow notch (2oc).
Thorax: 2 dc, 1 prsc, 1 pprn, 1 prs, ? keps setae, posterior prsc less than 0.8x 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 3.0x 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 more than 3 lines of setae, T3-4 posterior margin with 1 row of scarce setulae, T2 and T5 brown parts with setulae. S5 1.4x as long as wide, 1.7x as long and 1.1x as wide as S4, rectangular, setulose on posterior 2/3. Male genitalia with apical seta on cercus longer than epandrial setae, 1 seta on subepandrial plate, surstylus 0.5x as long as epandrium high, bent anteriorly, dilated apically (1.5x), 2.5x as long as wide, structure of lateral surface smooth, medial surface without setulae.
Body length: 2.1 mm; wing length: 2.3 mm.
