Diagnosis.

Atherigona lineata and its subspecies can be distinguished from other similar species by the combination of an infuscated frontal vitta and palpus, and a bifurcated hypopygial prominence. The subspecies A. lineata lineata, A. lineata torrida, and A. lineata ugandae can be distinguished from one another based on the following: A. lineata lineata and A. lineata torrida have the fore femur infuscated on at least the apical third (the fore femur of A. lineata ugandae is entirely yellow). Additionally, the shape of the lateral lobes of the trifoliate process and the depth of the bifurcation of the hypopygial prominence differs in these two subspecies. A. lineata ugandae has the hood area of the trifoliate process infuscated (hyaline for the other two) and has a much deeper, wider and pronounced bifurcation compared to others (Fig. 9).
