Formerly members of this genus were considered part of Eristalis though as rather a distinct group. They are very similar to Eristalinus, but Austalis is defined by having a postalar pile tuft but lacking the pile on posterior portions of the anepimeron and lacking the patterning on the eyes typical of Eristalinus. They also share a distinct metallic colouring. Little is known of their life histories but the adults have been recorded feeding at Eucalyptus flowers.[1] SystematicsList created by Thompson (2003) in defining the new genus.[1]
A further dozen species are known from the Oriental and Australasian regions but await formal description. {{Expand list|date=August 2009}}References1. ^1 {{cite journal | last = Thompson | first = F.
