Upper calypter dark brown, broader medially; marginal setulae dark brown. Halter dark orange.  Abdomen( Figs 2A, C). Tergites and sternites largely coppery red. T1 long black setulose; S2 black setulose; remaining tergites and sternites copper setulose. T1 with anterior and posterior margins black; cone-shaped elevation of the anterior portion of T1 bare, white pruinose with shiny apex. Tergites posterior to T1 and all sternites apruinose. Bulla black, about 6xlonger than wide. Female terminalia( Figs 3H–J). Sternite 8 with nearly parallel lateral margins, apically with well-defined lateral and medial lobes; lateral lobe with footprint shaped sclerotized area. Posterior margin of T9+10 regular, without medial protuberance; lateral margin convex, narrowing abruptly posteriorly. Capsule of medial spermatheca slightly curve.   Distribution( Fig. 4). Brazil( Minas Gerais).  Bionomics. The only two known specimens of  M. uai  sp. nov.were collected during the wet season in forested environment, by regular Malaise traps ( Townes 1962), which indicates that this species has some flight activity close to the soil level. As both exemplars are female, this flight activity might be related to oviposition.     Typematerial.  HOLOTYPE ♀. BRAZIL. Minas Gerais: Marliéria, Parque Estadual do Rio Doce, Gambá, 19°46′7.56″S, 42°35′3.81″W,  04–11.xi.2007, Malaise, J.C.R. Fontenellecol., AAM-001385 ( MZUSP). Paratype♀.  Samedata as holotype,  11–18.xi.2007( MZUSP).   Remarks. This species differs from  M. politusby the darker coloration on legs and postpedicel (missing in the holotypeof  M. politus, but present in the non-type specimens studied), and by the female terminalia concerning the shape of posterior and lateral margins of T9+10, and curvature of the medial spermatheca capsule.   Etymology. The specific epithet is taken from the informal interjection, commonly spoken in Minas GeraisState, which can express amazement, surprise or confirmation. 1324332085 2007-11-04 2007-11-11 2007-11-04 MZUSP Malaise, J.
