Taxonomic notes.

This species has a blackish thorax, brownish abdomen with white bands, as well as pale yellow legs, hypopygium and front portion of head. It is distinctive in having its body (including hypopygium) and posterior portion of head completely covered in dusty white pruinosity (Fig. 19A, B ). It was originally described by Thomson (1869) under Oscinis Loew; Malloch (1928) described another species P. seticauda , which was subsequently transferred to Lasiopleura ( Sabrosky 1955) and further synonymized under A. pruinosa ( Sabrosky 1989). Note that the images provided here are of the P. seticauda holotype specimen (Fig. 19A-D ). Chaetotaxy as observed: 1 vibrissa; 1 strong proclinate interfrontal setae; 2 postpronotal setae; 2 scapular setae; 1+1 notopleural setae; short weak reclinate biseriate acrostichal row; 1+3 dorsocentral setae; 1+1 supraalar setae; postalar and intrapostalar setae present; missing/indistinct prescutellar setae; scutellum without discal setulae; katepisternal seta missing/indistinct.
