Milichiella striata
Differs from congeners in the combination of shiny black mesonotum and brown microtomentose male T1-5 except for shiny lateral margin of T2, silvery broad lateral margin of T3-4, anterior margin of T4; anterior third of T5 silvery, posterior part shiny.
Male coloration and vestiture: frons subshiny black, ocellar triangle and orbital plates shiny black, lunule reddish, basoflagellomere basomedially red, face grey microtomentose, palpus black; thorax with mesonotum shiny black, scutellum brown microtomentose, pleura with anepisternum and large spot in middle of katepisternum shiny, otherwise brown microtomentose, wing white, veins yellow, brown spot at tip of vein R1 absent, calypter white with yellow margin, halter yellow, legs black, hind tarsus with light brush; abdomen with T1-5 brown microtomentose except for shiny lateral margin of T2, silvery broad lateral margin of T3-4, anterior margin of T4; anterior third of T5 silvery, posterior part shiny.
Morphology. Head: frons with 2+0.7 orbital and 2 frontal setae, anterior frontal seta ?slightly medioreclinate. In males frons 1.9x as wide at posterior margin than at base of antenna, arista about 2.9x as long as basoflagellomere wide, pubescence on arista very short, posterior eye margin with notch (5oc) and narrow emargination (1oc).
Thorax: 2 dc, 1 prsc, 1 pprn, 1 prs, 2 keps setae, posterior prsc about as long as posterior dc, seta between posterior prsc and posterior dc absent. Wing with vein R4+5 and M1 strongly converging (7), and ultimate section of vein M1 1.9x 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 scarcely setulose, anterolateral corner with more than 3 lines of setae, T3-4 posterior margin with one row of setulae, T5 shiny parts setulose. S5 1.9x as long as wide, 1.6x as long and 1.2x as wide as S4, posterior margin indented, strongly setulose with short setulae. Male genitalia with apical seta on cercus as long as longest epandrial setae; dorsal length of epandrium less than in lucidula; epandrium with striate anteroventral extension and 0 setae on subepandrial plate, surstylus 0.3x as long as epandrium high, dilated posteroapically (1.3x) with anterior margin straight and slight angle at anteroapical margin, 1.8x as long as wide, structure of lateral surface striate, medial surface without setulae, some sensilla at margin and a few in middle.
