Remarks. This new species differs from A. rufosignatus Kieffer, 1908 by having the clypeus with the apical margin rounded; the antennal scrobe ecarinate; the frontal angle of the ocellae forming a right angle; the pronotal disc without a transverse pronotal carina; and the mesopleuron with the lower fovea closed and not divided, whereas A. rufosignatus has the clypeus with the apical margin angulate; the antennal scrobe carinate; the frontal angle of the ocellar triangle obtuse; the pronotal disc with a transverse pronotal carina; and the mesopleuron with the lower fovea closed and divided.
