Hylomesa ugandensis (Turner), new combination 



Elis (Mesa) ugandensis Turner, 1918, pp. 86-87. 



This species, known at present only from the female, is distinguished 

 from all Hylomesa except bakeri by the much sparser punctation and 

 by the more sharply (right-angled) inferior margin of the hind femur. 

 The lack of anterior transverse ridges on the pronotum and first 

 tergum immediately separate ugandensis from bakeri. This species 

 is the only known Hylomesa from Africa. 



Female. — Length 17, forewing 11 mm. Head and appendages red 

 except tip of mandible, ventral surface of head in type (hypostoma 

 only in Gabun specimen), ocellar triangle, and last three flagellar 

 segments dark brown to black (type only) ; thorax black, tegula and 

 legs dark castaneous except foreleg with apex of femur, all of tibia 

 and tarsus light red in type; in Gabun specimen antenna and legs 

 are entirely red as well as pronotum, scutum, scutellum, most of 

 mesopleural disk, and part of lateral propodeal surface; wings entirely 

 and strongly infumated, with bronzy reflections; abdomen black, the 

 first two terga with bluish reflections. 



Head from above with length (apex of antennal insertions to occiput) 

 five-sixths (0.83) the greatest width (across eyes); clypeus with a 

 moderately strong median keel, gently rounded as seen in profile, 

 terminating just before anterior margin, the latter with a shallow
