Body bluish, with moderate to distinct metallic luster (figs. 33, 45, 55, 82–86); midbasitarsus basally or entirely dark brown, rarely orange brown; forewing bearing two dark stripes, one central, another apical or subapical (fig. 16); T2 and T7 with apical whitish stripe or spots....................................... M . cyaneus (Schmiedeknecht) – Body blackish, without or with weak metallic luster (figs. 38, 43, 56, 97); midbasitarsus basal half or more whitish to pale yellow, apex dark brown or black; forewing without stripes (fig. 10), or at most with small spots (fig. 11); T2 and T7 entirely black or dark brown (fig. 97)..........................................................

Ovipositor and legs with distinct reddish tinge (fig. 101); posterior transverse carina of propodeum complete (Fig, 105); forewing with a small brownish spot on its midlength and an infuscate apical area...................................... M. rufigladius , sp. nov. – Ovipositor and legs blackish or brownish, without reddish tinge; posterior transverse carina of propodeum incomplete, represented by three distinct apophyses (figs. 52, 54); forewing with two distinct brownish stripes on its midlength and subapically (figs. 17–19)...... 5 5 (4). Posterior half of mesosoma laterally covered with short, regular or sometimes sparse pilosity (fig. 46); forewing apical infuscation covering entire wing tip and areolet (figs. 2, 18); maxillary palpus with most articles patterned in whitish and dark brown; pleural carina fragmented or indistinct (fig. 49); orbital band on dorsal half of head narrow and widely interrupted above, or absent (fig. 2).................... M . delos Aguiar , sp. nov. – Posterior half of mesosoma seen laterally covered with conspicuous, dense silvery pilosity (as in figs. 45, 47); forewing apical infuscation not reaching the tip, which remains hyaline, and covering or not the areolet (figs. 17, 19); maxillary palpus articles uniformly colored, not patterned; pleural carina distinct (figs. 48, 50); orbital band on dorsal half of head wide and continuous at least above (figs. 72–73)........................................ 6 6 (5). Pleural carina linear (fig. 48); subalar ridge concolorous with mesepisternum (fig. 70); propodeum posteriad anterior transverse carina mostly rugulose, matte (fig. 52); S1 ending basad petiolar spiracle, even if very near to it.............. M . tesselatus Aguiar , sp. nov. – Pleural carina widely crenulate (fig. 49); subalar ridge light colored, contrasting with blackish mesepisternum (fig. 42); propodeum posteriad anterior transverse carina mostly smooth, shiny (fig. 50); S1 ending opposite petiolar spiracle...... M . hadroglyptus Aguiar , sp. nov. 7 (3). Mesosoma, including fore- and midlegs and hind coxa, orange (figs. 75–81). Wing infuscation weak and uniform or nearly so, at most narrowly darker on wing tip (fig. 14). Pleural carina distinct (fig. 44)....................................... M . aurantius , sp. nov. – Mesosoma, including all legs, black or dark brown. Wing infuscation intense or distinctly heterogeneous, wing darker apically, or centrally, or both (figs. 12, 20, 21). Pleural carina distinct or indistinct........................................................... 8 8 (7). Forewing more or less uniformly amber infuscate, except apex with diffuse darkened area which is often C-shaped (fig. 12); foretibia with two distinct longitudinal yellowish stripes (dorsolateral and ventromesal); body pilosity distinctly whitish or silvery. Southern and southeastern Brazil ............................................. M . tupan , sp. nov. – Forewing dark amber infuscate, with wide central and basal light amber areas at least partially discernible (figs. 20–21); foretibia entirely black or at most with ventromesal stripe only; body pilosity distinctly yellowish.
