Remarks. — This species is very similar to A. laevigata (Evans, 1958), however this species shows some different characteristics: head with vertex broadly straight, clypeus with rounded median lobe, genitalia with median region of aedeagus narrow, whereas A. laevigata has head with vertex broadly rounded, clypeus with emarginate median lobe, and the genitalia with two additional short processes arising near base of the parameres, and median region of aedeagus larger.
Etymology. — The name refers to the morphological pattern that is different from the other species of this genus.
