=Aecothea Haliday 1838
Oecothea Haliday in Curtis, 1837 is a conserved name (see WOZNICA A., ZATWARNICKI T. (1993) Oecothea Haliday in Curtis, 1837 (Insecta, Diptera): proposed conservation and designation of Helomyza fenestralis Fallén, 1820 as the type species. Bull. Zool. Nomencl. 50(1): 44-47

black bristles at the mid tibia (ref- Dr. Andrzej Woznica)
"The genus is easily distinguished from all others except Lutomyia by the presence of antero- and posterodorsal bristles (in addition to the dorsal preapical bristles) in the middle tibiae. The position of the anterior crossvein at or before the basal fourth of hte discal cell in Lutomyia will separate it from Aecothea and all other genera in the family." (Gill, 1962)
It is likely that all photos here are of the widespread Oecothea fenestralis (Fallén). O. aristata can be distinguished by the bare scutellum. The other two species are reliably distinguished by male genital characters, but darkened crossveins suggest fenestralis.
