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.
