Key to the Afrotropical species of Paralimosina

1 No strong setae on middle third of mid tibia. Male cercal lobes large (Figs 7, 8). Anterior lobe of male surstylus smaller than posterior lobe (Figs 9, 10). Female epiproct large, with laterally placed setal pair (Figs 14, 15). Facial plate entirely and frons partly yellow ......................................................................... flavifacies sp. n.

– Mid tibia with strong setae, also in the middle third. Male cercal lobes very small (e.g. Figs 24, 34) or absent. Anterior lobe of male surstylus larger then posterior lobe (Figs 29, 35). Female epiproct smaller, its setal pair is more central (e.g. Fig. 38). Facial plate and frons usually dark..................................................................2

2 Frons shiny, without M-shaped pattern. R-M–M-M much longer than M-M (up to 2× longer), lower edge of discal cell not rectangular.Anterior dc at least half as long as posterior dc ............................................................................... sinelineata sp. n.

– Frons dull, with M-shaped pattern. R-M–M-M ≤1.5× as long as M-M, lower edge of discal cell tends to be rectangular. Anterior dc weaker or even minute..............3

3 (3)–4–(5) (usually 4) pairs of short ifr, much shorter than (half as long as) anterior fr-orb. Costal index at least 1.0, usually much higher............................................4

– 3 pairs of long ifr, as long as anterior fr-orb. Costal index noticeably less than 1.0.................................................................................................................................5

4 Male mid tibia with a row of thick black spines ventrally on apical half but having only a few long hairs there. Male mid tibia with a medium-length va. Male fore coxa with long dense hairs medially. Costal index much greater than 1.0 ............... .......................................................................................................... australis sp. n.

– Male mid tibia without a row of thick black setae ventrally but apical 0.4 with long dense hairs. No va on male mid tibia. Male fore coxa with some longer hairs only. Costal index 1.0.......................................................................... paraustralis sp. n.

5 R-M–M-M twice the length of M-M.Aristal cilia at least 0.04 mm long. The posterior ifr pair is anterior to anterior fr-orb. Wing membrane not darkened ........................ ....................................................................................................... congoensis sp. n.

– R-M–M-M shorter or only slightly longer than M-M.Aristal cilia slightly longer than 0.01 mm. The posterior ifr pair is posterior to anterior fr-orb. Wing with a diffuse darkening around M-M .............................................................. heteroneura sp. n.
