Eristalis resolutus
Walker, 1858

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]

Systematics

List 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.
