Description. Females of this species are recognizable by the morphology of the clypeus, which has a flattened middle zone which is larger than in A. alfkenella alfkenella . The basal portion has a strong and dull microsculpture, while the apical segment is weak, generally shiny, and has evident PPs. The thorax has less dense and weaker PPs, with scarcer PPs in the front portion than in the posterior. Males have a clypeus like that of the female, although it is slightly flattened. The scutum has a weaker and shinier microsculpture than that of the male A. alfkenella alfkenella .
