Austalis
Introduction '''''Austalis''''' is a genus of Hoverflies, from the family Syrphidae, in the order Diptera.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.==Systematics== List created by Thompson (2003) in defining the new genus.*''A. aequipars'' (Walker, 1864)*''A. bergi'' (Curran, 1947)*''A. caledonica'' (Bigot, 1884)*''A. calliphoroides'' (Shiraki, 1963)*''A. ciliata'' (Meijere, 1913)*''A. conjuncta'' (Ferguson, 1926)*''A. copiosa'' (Walker, 1852)*''A. cupreoides'' (Goot, 1964)*''A. erythropyga'' (Walker, 1864)*''A. inscripta'' (Doleschall, 1857)*''A. latilimbata'' (Meijere, 1913)*''A. lucilioides'' (Walker, 1861)*''A. luciliomima'' (Hull, 1944)*''A. muscoides'' (Walker, 1858)*''A. muscomima'' (Hull, 1944)*''A. postscripta'' (Walker, 1864)*''A. pulchella'' (Macquart, 1846)*''A. refulgens'' (Doleschall, 1858)*''A. resoluta'' (Walker, 1858)*''A. rhina'' Thompson, 2003*''A. rhynchops'' (Bezzi, 1928)*''A. roederi'' (Bergroth, 1894)*''A. smaradgi'' (Walker, 1849)*''A. triseriata'' (Meijere, 1913)A further dozen species are known from the Oriental and Australasian regions but await formal description.
