A. densipennis group

This group is similar to the A. orientalis group, but the micro-punctures on the head and pronotum are dense and easily visible at low magnifications (x40). In addition the penultimate segment of the maxillary palpi is more triangular and the pigmented area of the head is produced beyond the insertion point of the antennae. The paramere is bilobed or, in one case ( A. densipennis), the lobes are fused to form one lobe.
