Key for identification of females of the species of the M. heliconius View in CoL species group
1. Inner tarsal claw of hind leg without a noticeable subapical narrowing, its width fairly uniform to the tip, which is rounded ( Figs. 17, 18 View FIGURES 17–22 ); clypeus shape variable, more often subquadrate ( Fig. 9, 10 View FIGURES 9–12 ); clypeus rarely with silvery or whitish bristles ( Fig. 22 View FIGURES 17–22 ); posterior ocelli variable, more often separated by one or more ocellar diameters ( Fig.13 View FIGURES 13–16 ); ground color more often yellow ( Fig. 2 View FIGURES 1–8 )............................................................................................. 2
- Inner tarsal claw of hind leg with an apparent subapical narrowing after which it widens again to the tip, which is rounded ( Figs. 19, 20 View FIGURES 17–22 ); clypeus looking high and narrow, distinctly higher than wide, apex quite projecting below, HCLP/WCLP often larger than 1.10 ( Figs. 11, 12 View FIGURES 9–12 ); clypeus always covered by distinct silvery or whitish bristles ( Fig. 21 View FIGURES 17–22 ); posterior ocelli always close, separated by less than one ocellar diameter ( Figs. 14–16 View FIGURES 13–16 ); ground color more often dark brown or black ( Figs. 5–8 View FIGURES 1–8 )....... 4
2. Ground color yellow, metasomal terga testaceous, 1–5 with variably distinct distal yellow bands ( Figs. 1, 2 View FIGURES 1–8 ); clypeus variable, more often subquadrate, but sometimes clearly higher than wide, HCLP/WCLP 1.05–1.14; occipital carina often weak, but sometimes stronger with vestige of lamella dorsolaterally; posterior interocellar distance variable (specimens from Pará and from the western limits of the distribution often with more extensive dark areas) ( Bolivia, Colombia, Guyana, Suriname, Brazil: Amazonia)........................................................................... M. iperuae Richards
- Ground color black, with few yellow marks, metasoma entirely (or practically) black, from tergum 2 backwards without distinct marginal band ( Figs. 3, 4 View FIGURES 1–8 ); clypeus relatively wide, subquadrate; occipital carina weak, without vestige of lamella dorsolaterally; posterior ocelli close, separated by less than one ocellar diameter................................... 3
3. Clypeus dark-yellowish brown, without whitish bristles ( Figs. 10 View FIGURES 9–12 , 22 View FIGURES 17–22 ); mesoaxilla marked with yellow; mid and hind tarsi yellow ( Fig. 4 View FIGURES 1–8 ) ( Brazil: AM).............................................................. M. ipixuna sp. nov.
- Clypeus black with numerous distinct whitish bristles; mesoaxilla dark; tarsi brown ( Colombia: Leticia)... M. ticuna sp. nov.
4. Ground color brown or light brown ( Figs. 5, 6 View FIGURES 1–8 ), at least first metasomal tergum not entirely black, clypeus yellow ( Fig. 11 View FIGURES 9–12 ).. ................................................................................................... 5
- Ground color black or brownish black, whole metasoma black (sometimes first tergum with lateral yelow spot) ( Figs. 7, 8 View FIGURES 1–8 ), clypeus black or yellowish brown ( Fig. 12 View FIGURES 9–12 )................................................................. 7
5. All metasomal terga brown, 1–5 with distal yellow bands; mesoscutum light brown with two yellow median stripes, and a black posterior triangular mark ( Figs. 5, 6 View FIGURES 1–8 ); pterostigma yellowish; all three tarsi yellow ( Brazil: PA)......... M. gorotire sp. nov.
- Metasomal terga 1, and 2 (basally) light brown, distal third of 2 to 6 black; mesoscutum brown, with or without yellow stripes, without posterior black mark; pterostigma brown; tarsi ligh brown.............................................. 6
6. Occipital carina hardly developed; mesoscutum brown with two elongate fine median yellow stripes, and two marginal streaks adjoining tegula; propodeum with pair of wide lungshape yellow spots; metasomal tergum 1 with evanescent distal band ( Guyana)........................................................................... M. heliconius Richards View in CoL
- Occipital carina more apparent at sides; mesoscutum uniformly brown; propodeum spots not so wide, more parallel-sided; metasomal tergum 1 with more distinct distal yellow band ( Bolivia)............................. M. sericeus Richards View in CoL
7. Clypeus dark-yellowish brown ( Fig. 12 View FIGURES 9–12 ); scutellum brownish black, unmarked; metanotum brown with narrow anterior yellow band; propodeal spots evanescent, with margins blurred; all three tarsi yellow ( Figs. 7, 8 View FIGURES 1–8 ); pterostigma yellowish ( Brazil: PA)..................................................................................... M. luciliae sp. nov.
