Comments and Corrigenda The common Phaonia variegata (now P. subventa) is best separated from the very rare P. bitincta, by the length of the aristal hairs being less than half the diameter of the flagellomere. (The presutural dark thoracic stripes are not as wide as given; and one mid-tibia may have the third bristle, though rarely both.)
Coverage Covers all UK species known at the time.
Illustrations A few well-chosen line drawings in the text, line drawings of Fannia genitalia at the back.
Identify Under a Stereo Microscope.
Specimen Prep. Pinned specimens set so that sternopleuron is visible. Genitalia preps useful for Fannia.
Difficulty Moderately straightforward (the easiest of the old Calypterate keys), although Fannia are challenging.
