Typxrs: Holotype (male), allotype (female), and paratype (female), 
all brachypterous, Kasango, Kivu Province, Congo, October 9, 1954, 
USNM 65112. 
Remarks: The allotype of U. engaeus is illustrated in figure 4. 
The species differs from U. testudineatus Distant of South Africa in 
having shorter antennae, wider paranota with outer margin strongly 
sinuate, and the discoidal and claval areas fused. U. testudineatus 
is a smoother and more evenly reticulated species without adventitious 
veins in subcostal and discoidal areas.
