Distribution. So far only known from the provinces of Benguela, Cuanza Sul, Huambo and Huila in Angola ( Fig. 4 D View Fig ).

Remarks. This is the largest species in the genus, attaining a TL = 11.4-13.0 mm ( Antoine 2000; Beinhundner 2017). It occurs sympatrically with A. spoliata across its entire distribution range, but can easily be separated from the latter by its generally larger size, brownish-green pronotum, presence of fewer and smaller white maculae on the dorsum ( Fig. 3 A View Fig ) and especially by the hypertrophy of the external lobes of its aedeagal parameres ( Fig. 3 F, G View Fig ). Like in the pre- vious species, adults have been collected from September to December, indicating a potential peak in activity during the spring and summer seasons. It is presumably floricolous and stem/leaf feeder like the other species of the genus, but unfortunately there are yet no data or observations available to confirm this. The immature stages are unknown.
