Mid November 2016
This fly largely fits subgenus Parascaptomyza (ie dorsocentral bristles 0+2; acrostichal brisltes in two rows; one prominent humeral bristle; head about as long as high; and arista with long rays). Scaptomyza (Parascaptomyza) elmoi is the only species listed from this subgenus for Australia but the fly photographed here has arista rays one more in number above and below than what is described for that species.
Winglength approx. 2.2mm.
