Dolichopus bolsteri was described from one male collected at Little River , Newfoundland , Canada . The male is described having a wide face and rather short postabdomen with small cerci. Photos of the holotype male ( MCZ , https://mczbase.mcz.harvard.edu/guid/ MCZ :Ent:7615) show clear signs of demasculinization: the hypopygium is characteristically small and poorly rotated (and in one photo can be seen projecting out to one side of abdomen) .
