Paratypes. I $ with the holotype (BMNH), I <$ emerged v. 1969 (0. W. Richards) 

 (BMNH). 



I think that this is a good species, although the variation in the genus Micrapion is 

 rather puzzling. M. richardsi has the pronotal depressions similar to M . biimpressum, 

 but the form of the female gaster is different, more like that of M. congoense, apart 

 from the rather strange lack of conspicuous pubescence on the eyes. 



Micrapion congoenese Steffan 

 (Text-figs 261-263) 



Micrapion congoense Steffan, 1948 : 85, £■ Holotype $, Zaire: Kiwu Region, Kadjudju (MNHN, 

 Paris) [examined]. 



I think that this is a good species, although very close to M. bilineatum 

 Kriechbaumer. Eventually when more is known it might prove to be a northerly 

 subspecies of bilineatum, differing mainly by the more slender hind femora and 

 usually darker colours. In the specimens examined the hind femur is 1-78-2-00 

 times as long as broad (teeth included), with a more slender femur in smaller 

 specimens. The length of the sheaths varies between 0-62-0-76 the length of 

 hind tibia. Steffan differentiated M. congoense from M. (nyassicum =) bilineatum 

 on the lack of the pale markings on the thorax, but I find great variation; in the 

 richer-marked specimens the pronotum has anterior and posterior bands, mesoscutum 

 narrowly bordered lateral margin, scutellum the posterior margin. The length of 

 body in female 4-9-6-9 mm, in male 5-2-6-2 mm. The male has the gaster much as 

 shown in M. bilineatum (Text-fig. 260), but the hind femur is more slender.
