Adults
1 Ground colour of body green or yellow, sometimes with white or dark dots (Figs 107, 108)........................... 2
- Ground colour of body ochreous, brown, black or multicoloured (Figs 105, 106)................................... 3
2 Body dimensions small: antenna <1.2 mm, forewing <1.8 mm. Genal processes <0.7 times as long as vertex along midline (Fig. 117). Surface spinules in apical half of forewing reduced to small patches mostly along apical wing margin. Male and female terminalia as in Figs 132, 135, 151, 152, 163. Paramere narrowly lamellar, lacking a group of densely spaced bristles in apical third along hind margin. Aedeagus hardly expanded apically, bearing a distinct hook apically. Female proctiger strongly indented distal to circumanal ring, 1.4–1.5 times as long as head width. On Copaifera cearensis ............. M. megacerca
- Body dimensions large: antenna> 2.2 mm, forewing> 2.1 mm. Genal processes> 0.7 times as long as vertex along midline (Fig. 119). Surface spinules in apical half of forewing forming large patches, leaving spinule-free stripes along the veins. Male and female terminalia as in Figs 133, 155, 156, 165. Paramere clavate, bearing a group of densely spaced bristles in apical third along hind margin. Aedeagus strongly expanded apically, bearing two ventral ridges but lacking apical hook. Female proctiger weakly indented distal to circumanal ring, 1.0–1.2 times as long as head width. On Copaifera langsdorffii ........ M. viridis
3 Genal processes short, <0.6 times as long as vertex along midline (Figs 113–115). Forewing slightly angular near apex of vein Rs (Figs 122–124).................................................................................... 4
- Genal processes moderately long,> 0.4 times as long as vertex along midline (Figs 111, 112, 116, 118). Forewing evenly rounded near apex of vein Rs (Figs 120, 121, 125, 127)....................................................... 7
4 Forewing with dark subapical band (Fig. 122). Distal portion of aedeagus only weakly expanded apically (Fig. 143). On Copaifera cearensis ............................................................................... M. compta
- Forewing without dark subapical band, usually with dark marginal spots in the middle of cells (Figs 123, 124). Distal portion of aedeagus strongly expanded apically with a subapical tooth (Figs 145, 147). On other Copaifera spp................. 5
5 Forewing membrane infuscate in addition to brown patches along wing margin (Fig. 124). Paramere with slightly angular hind margin in apical third (Fig. 146). Apical dilatation of distal portion of aedeagus small, subapical tooth approximately in apical quarter (Fig. 147). Female proctiger <1.0 mm (Fig. 161). On Copaifera oblongifolia ..................... M. fumipennis
- Forewing membrane colourless apart from brown patches along wing margin (Fig 123). Paramere and aedeagus different (Figs 144, 145). Female proctiger> 1.0 mm (Fig. 160)............................................................ 6
6 Paramere, in profile, more or less evenly tapering to blunt apex, in apical half (Fig. 144). Apical dilatation of distal portion of aedeagus with subapical, ventral tooth large, blunt (Fig. 145). Brazil ................................... M. copaiferae
- Paramere, in apical half, more or less subparallel, strongly tapering subapically, in profile. Apical dilatation of distal portion of aedeagus with subapical, ventral tooth narrow, pointed (Brown & Hodkinson 1988: 76, Figs 33 F–H). Panama. M. minuticonis
7 Genal processes blunt (Figs 111, 118). Body dimensions larger, forewing length> 2.0 mm. Paramere clavate, relatively evenly widening towards apical fifth, with a few bristles on the inner face in the middle near apex (Fig. 138, 153). Female terminalia long,> 1.3 times as long as head width; proctiger at most weakly upturned apically (Figs 157, 164).................... 8
- Genal processes subacute (Figs 112, 116). Body dimensions smaller, forewing length <2.5 mm. Paramere lamellar, suddenly widened near apex, with a group of dense bristles on the inner face along the hind margin near apex (Figs 140, 148). Female terminalia short, <1.3 times as long as head width; proctiger strongly upturned apically (Figs 158, 162)................ 9
8 Genal processes 0.7–0.9 times as long as vertex along midline (Fig. 111). Large, antenna> 2.6 mm long, forewing> 2.4 mm long. Sclerotised apex of paramere hook-shaped, forward directed (Fig. 136). Aedeagus with two large subapical spines (Fig. 139)......................................................................................... M. adusta
- Genal processes 0.5–0.7 times as long as vertex along midline (Fig. 118). Small, antenna <2.5 mm long, forewing <2.5 mm long. Sclerotised apex of paramere truncate with slightly larger anterior and smaller posterior point (Fig. 137). Aedeagus lacking subapical spines (Fig. 154).................................................................... M. repens
9 Paramere weakly expanded apically (Fig. 140). Apical dilatation of aedeagus about one third length of distal segment (Fig. 141). Setae on female subgenital plate sparse, leaving a conspicuous seta-free patch in the middle on either side (Fig. 166). On Copaifera cearensis ........................................................................... M. borealis
- Paramere strongly expanded apically (Fig. 148). Apical dilatation of aedeagus about half length of distal segment (Figs 149, 150). Setae on female subgenital plate dense, without seta-free patch in the middle on either side (Fig. 167). On Copaifera langsdorffii and C. marginata .................................................................... M. gloriae
