Note: McCafferty et al. (2017) state that the keys given here are not reliable. The larvae are best resolved to species by rearings to male aadults, keeping in mind that the taxonomy, that is based on adults is itself in some doubt. Therefore the following keys are tentative.

1.              Posterior margin of dorsum of adominal segment 9 brown with anterior part of segment                 mostly pale; pale V-shaped area absent. . . . . . . . . . . . . . . . Leucrocuta maculipennis

                               
                V-shaped pale median triangle present on dorsum of abdominal segment 9 and covering                 most of middle of segment, its apex extendiing almost to posterior margin. . . . . . . . . . 2

2.             Light areas on femora usually more extensive than dark areas; dark area present at each                 posterolateral angle of venter of abdomen segment 9, sometime smaller dark area also                 present at each anterolateral angle of segment 9, but the dark areas are not connecgted to                 form a continuous dark margin. . . . . . . . . . . . . . . . . . . . . . . . . . . . . Leucrocuta hebe
 

                Dark areas on femor usually more extensive than light areas; dark areas of posterolateral                angle of venter of segment 9 complete or almost complete, forming a dark margin, not                 divided inot poateior or anterior areas. . . . . . . . . . . . . . . . . . . . Leucrocuta aphrodite
