Key to females of Drepanoneura
[female of D. janirae unknown]
Unlike males, known females can be easily identified by their unique modifications of prothoracic hind lobe.
1. Posterior lobe of prothorax lacking processes (Figs. 4–5)...........................................................................2
1'. Posterior lobe of prothorax with processes (Figs. 3, 6–9)...........................................................................3
2. Posterior lobe of prothorax with a medial shallow concavity (Fig. 5); ventral side of sub-basal plate of ovipositor convex (Fig. 36 d); Panamá Prov. in Panama (Fig. 37)...................................................... D. letitia
2'. Posterior lobe of prothorax linear to slightly bilobate (Fig. 4); ventral side of sub-basal plate of ovipositor concave (Fig. 36 c); Amazonas Dept. in Colombia (Fig. 37)........................................................... D. flinti
3. Posterior lobe of prothorax with a dorsal or ventral medial projection (Figs. 6, 8–9)................................4
3'. Posterior lobe of prothorax lacking a medial projection (Figs. 3, 7)...........................................................6
4. Posterior lobe of prothorax with a ventro-medial semicircular projection and lacking lateral projections (Fig. 8); dorsal and ventral sides of sub-basal plate of ovipositor linear (Fig. 36 i); Loreto Dept. in Peru (Fig. 37) ................................................................................................................................ D. peruviensis
4'. Posterior lobe of prothorax with a medio-dorsal triangular projection (Figs. 6, 9); dorsal side of sub-basal plate of ovipositor slightly concave and ventral side slightly convex (Figs. 36 f, j)....................................5
5. Posterior lobe of prothorax on each side with two lateral processes, a cylindrical ventro-lateral process and a flat short dorso-lateral process (Fig. 6); Morona-Santiago Prov. in Ecuador to Madre de Dios Dept. in Peru (Fig. 37)........................................................................................................................... D. loutoni
5'. Posterior lobe of prothorax on each side with one laminar ventro-lateral process (Fig. 9); Sucumbíos to Napo Provs. in Ecuador (Fig. 37) ........................................................................................... D. tennesseni
6. Posterior lobe of prothorax smoothly concave, with only one small, as long as wide ventro-lateral laminar process on each side (vl, Fig. 3); Antioquia to Tolima Depts. in Colombia (Fig. 37).............. D. donnellyi
6'. Posterior lobe of prothorax medially cleft, with two lateral processes on each side: a larger, outer, erect, dorso-lateral laminar process (dl, Fig. 7), and a smaller, inner, ventro-lateral process (vl, Fig. 7); Orellana Prov. in Ecuador to Madre de Dios Dept. in Peru (Fig. 37) ........................................................
