The subgenus
1 | Mandible mainly horizontal, its second tooth situated at inner side of mandible and in same plane as apical (upper) tooth, small or obsolescent (Figs |
|
– | Mandible more vertical, its second tooth situated ventrally to apical tooth of mandible (not in same plane) and medium-sized or small. Ovipositor of female straight or sometimes somewhat curved apically. Posterior half of second tergite usually largely or entirely smooth, and without lateral crease. Anterior ocellus situated at same level as posterior ocelli |
|
2 | Vertex with deep median longitudinal groove. POL ~ 2.5 times diameter of posterior ocellus and at least twice distance between anterior and posterior ocelli. Third abscissa of costal vein (2-SC+R) of hind wing comparatively long |
|
– | Vertex without median longitudinal groove. POL 1.5–2.0 times diameter of ocellus and at most 1.5 times distance between anterior and posterior ocelli. Third abscissa of costal vein (2-SC+R) of hind wing variable, but usually medium-sized or short |
