A. orientalis group

In this group only one terminal segment in the maxillary palpi is pubescent. The terminal segment is narrow and elongate and either symmetric or only slightly asymmetric (except A. makhoreae ). The penultimate segment is widened toward the apex, but it is more or less parallel-sided at the apex. The head has two pairs of interocular setae. The micro-punctures on the head and pronotum are absent or sparse and localised. There is either no or only a narrow pigmented strip in front of the antennal insertion on the head, so that it looks as though the antennae are inserted right on the front margin (except A. makhoreae ). The paramere is bilobed or, in one case ( A. tshuapensis ), the lobes have fused to form one lobe. The apices of the styles of tergite IX are thickly covered in bristles so that their outline is invisible (Fig. 30).
