Aegilips atricornis Fergusson, 1985: 813 (♂).
Diagnosis
Species very similar to A. nitidulus, from which it can be distinguished by the presence of incomplete notauli, the absence of median mesoscutal furrow and carinate sculpture on the mesoscutum (notauli complete, median mesoscutal furrow present and mesoscutum with some transverse carinae in A. nitidulus). It can be distinguished from A. flavidicornis, A. longicellus, A. paucus and A. zaitzevi (which also lack complete notauli) despite having incomplete notauli, they are clearly excavated, almost complete in some individuals (notauli very superficial and never exceeding than one third of the scutellum length in A. flavidicornis, A. longicellus, A. paucus and A. zaitzevi).
