KEY TO THE OLD WORLD SPECIES OF CEROPTERA MACQUART

(Trichocypselalongiseta Villeneuve, 1916 ismostprobablyconspecificwith Ceropterellanitidosa (Richards, 1953); Ceropteraghesquierei Vanschuytbroeck, 1951 and C. lacteipennis ( Villeneuve, 1916) were not considered.)

1. Morethan 1 pair (0+2,1+2 pairs) ofdorsocentralsetae. 2

– Only 1 posterior (prescutellar) pairofdorsocentralsetae. 11

2. Scutellumwithseveral (c. 6 pairs) ofadditionaldiscalandlateralscutel- larsetae. 0 + 2(3) dorsocentralpairs, anteriorpairshorter. Also 1 anterodorsal seta in the basal half of mid tibia. Kenya. C. setiscutellata sp. n.

– Only 2 pairsoflongscutellarpairspresent. 3

3. Largereddishspecies ( Fig. 97 ). Bodylength 3.5–4.0 mm. Alsolegsmostly red. Male sternite 5 with a medio-caudal lobe covered by dense short setulae (see e.g. Fig. 13) 4

– Smallerspecies, bodylength 2–3 mm. Bodymostlyblack. 7

4. 0 + 2 dorsocentralpairs. Midtibiaandbasitarsuswithextremelylarge anddensehairs. 5

– 1 + 2 dorsocentral pairs. 6

5. Malemidbasitarsuswithshortdensesharpblacksetae. Secondcostal section twice longer than third section. C. crispa ( Duda, 1925)

– Malemidbasitarsuswithlongdensehairsonly. Secondcostalsection 1.5 times as long as third section. C. catharsi Richards, 1953

6. Midbasitarsusslightlylongerthan 2ndtarsomere, withdense, notblack thornlets. Malegenitalia (Figs 39–43). C. setigera Vanschuytbroeck, 1945

– Midbasitarsus 1.5 timesaslongas 2ndtarsomere, withsparseblack thornlets. Malegenitalia (Figs 13–18). C. nasuta ( Villeneuve, 1916)

7. Presuturaldorsocentralsetaalwaysdistinct. 8

– 0 +2 dorsocentralpairs, i.e. presuturalpairnotdiscernible. 9

8. Outerpostpronotal (humeral) setamuchlongerthananteriordorsocentralseta. Apicalscutellarsetatwicelongerthanbasalscutellar. Height of eye ca. equal to the height of gena. Wing membrane brownish, veins brown. Tipofwingusuallydarkerbrownthancentralpart (female), or, uppermarginofwingbroadlydiffuselybrowned (male). Secondcostal section as long as third section. Morocco. C. picta ( Becker, 1913)

– Outerpostpronotalsetaaslongasoronlyslightlylongerthananterior dorsocentralseta. Basalscutellarsetanearlyaslongasapicalpair. Height of eye ca. 1.7 times higher than height of gena. Wing membrane yellowish, veinsyellow. Wingunicolorous. Secondcostalsection 1.5 timesas long as third section. C. rufitarsis (Meigen, 1830)
