Diagnosis: A. lineata and its subspecies can be distinguished from other species with infuscated frontal vitta by the combination of infuscated palpi and a bifurcated hypopygial prominence. A. lineata lineata , A. lineata torrida Deeming, 1971 and A. lineata ugandae van Emden, 1940 can be distinguished from one another on the following grounds: A. lineata lineata and A. lineata torrida have the fore femur infuscated on at least the apical third (compared to L. lineata ugandae that has it entirely yellow) and the two former species differ from one another in terms of the shape of their trifoliate processes’ lateral lobes ( Fig. 51a vs. Fig. 52a ) and the depth of the hypopygial prominence bifurcation. A. lineata lineata and A. lineata torrida again differ from A. lineata ugandae in that ugandae has the hood area of the trifoliate process infuscate compared to hyaline for the other two subspecies, and also ugandae has a much deeper, wider and pronounced bifurcation.
