Key to Loneura species from Brazil (males)

Loneura brasiliensis Roesler , is not included, because only the female is known.

1. Hypandrium of three sclerites, two small, elongate side sclerites flanking a large, central sclerite ( Fig. 10 ).... Loneura group I................................................................................................... 2

- Hypandrium of one sclerite, resulting from the fusion of the proximal ends of the side sclerites to the central sclerite, this extended mesally on each side, with two posterior processes in the middle, variously shaped ( Fig. 29 ).... Loneura group II.....3

2. Central sclerite of hypandrium with one posterior projection, distally bifurcated, with a postero-lateral connection joining the central and lateral sclerites ( Fig. 10 )........................................................ L. manauara n. sp.

- Hypandrium with more than one posterior projection......................................................... 4

3. Posterior projections of the hypandrium near to each other, projected from the middle, distally curved outward, with deep median incision that reaches near the base ( Fig. 29 ).................................................. L. duckei n. sp.

- Posterior projections of the hypandrium widely separated, projected from postero-lateral corners, distally curved inward, without deep median incision ( Fig. 33 )......................................................... L. amazonica (New)

4. Central sclerite of hypandrium with two posterior projections, with pointed apices.......... L. maracaensis García Aldrete

- Central sclerite of hypandrium with more than two posterior projections.......................................... 5

5. Central sclerite of hypandrium with three posterior projections ( Fig. 17 , 35 )....................................... 6

- Central sclerite of hypandrium with four projections, two posterior and two latero-mesal.............. L. digitiformis n. sp.

6. Posterior border of the central sclerite of the hypandrium, between the short posterior processes, convex, rounded ( Fig. 35 )............................................................................... L. baiana Moura Lima et al.

- Posterior border of the central sclerite of the hypandrium with a short, distally rounded median process ( Fig. 17 )............................................................................................... L. marinonii n. sp.
