Dolichopodinae is a subfamily of flies in the family Dolichopodidae. It is recognised by the antennae having setae on the top side of the scape (the first segment of the antennae), the femora of the middle and hind legs having setae on the front side near the apex, and the male postabdomen (the terminal segments of the abdomen containing the anal and genital segments) usually being large, forming a peduncle and folded underneath the abdomen.
Systematics The subfamily Dolichopodinae is divided into two tribes, Dolichopodini and Tachytrechini, in Negrobov (1986, 1991). In Brooks (2005)'s phylogenetic analysis of the subfamily, these tribes are not supported, and four informal generic groups are instead recognised.
The following list of genera generally follows Grichanov (2017):
