Milichiella laselvae
Differs from congeners in the combination of distinctive brown spot on R1 and the brown microtomentose line between the silvery and black parts of T5.
Male coloration and vestiture: frons black, ocellar triangle and upper orbital plates subshiny, lunule brown, basoflagellomere basomedially yellow, face with antennal grooves silvery microtomentose, epistom brown microtomentose, palpus black; thorax with mesonotum slightly brown microtomentose, scutellum and pleura same, wing hyaline, veins brown, brown spot at tip of vein R1 strong, calypter brown with dark margin, halter black, legs black except for base and tip of fore and mid tibia, and yellow basitarsi, fore and hind tarsus with conspicuous yellow brush; abdomen with T2-5 silvery microtomentose except for shiny black tip of T5 and brown microtomentose margin between silvery part and tip.
Morphology. Head: frons with 2+0.8 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 2.7x as long as basoflagellomere wide, pubescence on arista very short, posterior eye margin with slight notch (2-3oc) and slight emargination (1oc).
Thorax: 2 dc, 2 prsc, 1+0.8 pprn, 2+0.8 prs, 2 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 strongly converging (3.9), and ultimate section of vein M1 2.0x as long as penultimate section. Fore femur normal setulose, tibial organ absent.
Male abdomen: posteromedial triangular projection of T1 into T2 present. Tergal chaetotaxy: T2 anterolateral corner with 2-3 lines of setae, T2 posterior half setulose, T3-4 posterior margin with 1-2 rows of setulae, T5 posterior margin of silvery part and black part setulose. S5 1.2x as long as wide, 1.9x as long and 1.9x as wide as S4, setulose on posterior ¾. Male genitalia with apical seta on cercus longer than epandrial setae, 1 seta on subepandrial plate, surstylus 0.4x as long as epandrium high, slightly dilated apically (1.1x), 1.4x as long as wide, structure of lateral surface smooth, medial surface without setulae.
Body length: 3.7 mm; wing length: 3.7 mm.
