Key to species of Megarhyssa View in CoL View at ENA occurring in Mexico
1. Metasoma laterally yellow, with broad dorsal longitudinal black stripe extending entire length of metasoma ( Fig. 7 View FIGURES 4 – 7 ). Fore wing hyaline with conspicuous subapical dark mark at apex of the radial cell ( Fig. 8 View FIGURE 8 ). Flagellum of antenna blackish with broad subapical pale band ( Fig. 2 View FIGURES 1 – 3 ). Ovipositor sheath 3.4 × as long as fore wing ( Fig. 1 View FIGURES 1 – 3 )....................... M. gratiosa sp. nov.
- Metasoma with variable amount of yellow, reddish orange and black; tergites often transversely banded or with dorsal and/or lateral marks, but never with continuous median black stripe extending along entire length of metasoma. Fore wing without apical dark mark, or with radial cell darkened only at base ( Townes & Townes 1960: Fig. 319, d–g). Flagellum of antenna more or less entirely black, sometimes somewhat lighter in the apical half, never with contrasting pale band. Ovipositor sheath about 1.9–3.0 × as long as fore wing........................................................................... 2
2. Hind leg with coxa and tarsus entirely black, femur and tibia black in basal 0.8 and yellow in apical 0.2. Head and mesosoma black with yellow markings ( Kasparyan 2002: Figs 1, 2 View FIGURES 1 – 3 ). Metasoma extensively black, tergites 1 and 2 with pre-apical dorsomedian yellow marks, tergites 3+ with lateral yellow markings ( Kasparyan 2002: Figs 1, 3 View FIGURES 1 – 3 ). Malar space 1.4 × as long as apical width of mandible. Ovipositor sheath 1.9 × as long as fore wing. [Distribution: Central Mexico (State of Mexico)]......................................................................................... M. verae Kasparyan, 2002 View in CoL
- Hind leg predominantly brownish orange with yellow marks. Head and mesosoma predominantly yellow and brown. Metasoma yellow to reddish brown, with more or less distinct transverse pre-apical yellow bands on tergites. Malar space about 0.7 × as long as apical width of mandible. Ovipositor sheath about 3.0 × as long as fore wing. [Distribution: southern U.S.A. from Texas to Georgia and Florida, northern Mexico (Chihuahua).]................
