Fig. 19

Atherigona marginifolia van Emden, 1940: 122 , figs 44, 13; Deeming 1971: 163, figs 77, 78; Deeming 1979: 40, figs 20–22.

Diagnosis: This species has a very characteristic trifoliate process and hypopygial prominence which combined with its one third yellow to two thirds infuscated frontal vitta and ferruginous postpedicel with half infuscated dorsal edge and apex make it quite distinct. The median piece of the trifoliate process has a pair of well-developed apical setae and the hypopygial prominence as in Figure 19c, d .
