Distribution, phenology and biology.

Collected at four localities in northern Namibia (Fig. 16 ), mostly in the vicinity of the Kunene River, during the months of August and October (Table 1 ). The habitats have been described as 'shaded woodland’ and 'riverine forest’. Much of the material was collected in malaise traps, which is surprising as small, ground-dwelling asilids are not usually collected in significant numbers with such traps. The fact that over 30 specimens were collected in 3 days suggests that population numbers were high and, as only eight were female, it appears that males are more active fliers than females.
