Key to the species of the megacantha View in CoL clade

1. Oviscape less than 7 mm long, less than 1.5 times as long as mesonotum.......................................... 2

- Oviscape approximately 10 mm long, more than 2 times as long as mesonotum. Brazil (Amazonas)..... megacantha Zucchi View in CoL

2. Cell c length (measured from crossvein h to subcostal break)/pterostigma length (distance between apices of veins Sc and R1) less than 1.0. Apex of vein M extended to S-band ( Figs. 40–41, 44–46 View FIGURES 38 – 49 ). Aculeus tip slightly tapered then bluntly triangular and minutely serrate ( Figs. 94, 96 View FIGURES 94 – 99 )........................................................................... 3

- Cell c length/pterostigma length greater than 1.1. Apex of vein M not extended to S-band ( Figs. 42, 47–49 View FIGURES 38 – 49 ). Aculeus tip gradually tapered or with large subapical notch, nonserrate ( Figs. 95, 97–99 View FIGURES 94 – 99 )........................................... 4

3. Setae red brown to black ( Figs. 9–10 View FIGURES 9 – 10 ). Oviscape 2.42–2.67 mm long, 0.70–0.76 times as long as mesonotum. Aculeus 2.06–2.19 mm long; tip ( Fig. 96 View FIGURES 94 – 99 ) 0.075–0.105 mm long, 1.07–1.23 times as long as wide, apical 0.48–0.53 bluntly triangular and finely serrate. Ecuador............................................................... hyperacantha View in CoL , n. sp.

- Setae orange to orange brown, sometimes red brown on head ( Fig. 7 View FIGURES 7 – 8 ). Oviscape 4.21–4.52 mm long, 1.09–1.14 times as long as mesonotum. Aculeus 3.80 mm long; tip ( Fig. 94 View FIGURES 94 – 99 ) 0.13–0.145 mm long, 1.53–1.71 times as long as wide, distal 0.17–0.23 minutely serrate. Ecuador................................................................ hadracantha , n. sp.

4. Vein M relatively strongly curved apically; cell r4+5 0.84–0.95 times as wide at apex as at level of dm–cu ( Figs. 47–49 View FIGURES 38 – 49 ). Oviscape 4.40–5.96 mm long, 1.26–1.39 times as long as mesonotum. Aculeus 4.16–5.55 mm long; tip ( Figs. 97–99 View FIGURES 94 – 99 ) 0.06–0.08 mm long, 0.04–0.05 mm wide, 1.2–2.0 times as long as wide, slightly tapered but with large notch on distal third......... 5

Aculeus 2.00 mm long; tip ( Fig. 95 View FIGURES 94 – 99 ) 0.23–0.24 mm long, 0.07–0.08 mm wide, 3.00–3.29 times as long as wide, elongate triangular, gradually tapered, without notches. Setae orange to orange brown, sometimes red brown on head. Ecuador...................................................... haplacantha View in CoL , n. sp.

5. Setae orange ( Fig. 24 View FIGURES 22 – 25. 22 – 23 ). Aculeus tip slightly constricted subapically, with weak apical notches ( Figs. 97, 98 View FIGURES 94 – 99 ). Trinidad.............................................................................................. inaequalis View in CoL , n. sp.
