Milichiella booloombae
Differs from congeners in the combination of dark brown mesonotum, 3+1 dc, and male T2-5 silvery microtomentose except for brown microtomentose anterior third and middle of T2 and posterior half of T5.
Male coloration and vestiture: frons brown, ocellar triangle and orbital plates brown microtomentose, lunule brown, basoflagellomere black, face greyish microtomentose, palpus black; thorax with mesonotum dark brown microtomentose, scutellum and pleura same, wing hyaline, veins brown, brown spot at tip of vein R1 weak, calypter hyaline with brown margin, halter black, legs black; abdomen with T2-5 silvery microtomentose except for brown microtomentose anterior third and middle of T2 and posterior half of T5.
Morphology. Head: frons with 2 orbital and 2 frontal setae, anterior frontal seta medioreclinate. In males frons 2.3x 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 wide notch (6oc) and slight emargination (1oc).
Thorax: 3+1 dc, 4+1 prsc, 1 pprn, 1+0.7+row prs, 2+0.8 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 (1.7), and ultimate section of vein M1 2.3x 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+T5 posterior half setulose, T3-4 posterior margin with 2 rows of setulae. S5 1.1x as long as wide, 1.5x as long and 2.1x as wide as S4, posterior margin indented, long and strongly setulose. Male genitalia with apical seta on cercus slightly longer than epandrial setae, 1 seta on subepandrial plate, surstylus 1.1x as long as epandrium high, bent posteriorly, dilated apically (1.3x), with small edentation at posterior base of dilation, 9.4x as long as wide, structure of lateral surface smooth, medial surface with long setulae along anterior margin.
Special characters: all setulae long; mesonotum with only few setulae; mid femur with long setae antero- and posteroventrally in male.
Body length: 3.2 mm; wing length: 3.3 mm.
