At the altitude of approximately 250 of Mt. Sori located in Kyung-gi Co, Korea authers have made a field collection of Drosophila during June, 1 and 15, 1961, and found about 30 specimens which seemed to be a new species belonging to Genus Drosophila, Subgenus Hirtodrosophila. AUthors have named the species : D. macromaculata sp. nov. " Its Korean name is given , : Uluck-muni-chopari". This species is very similar to Drosophila cheda in its external feature and especially it that each of four stripes in the mesonotum is cut into tow, and it also resembles with Drosophila calloptera in that it has three distinct spots in the wing. Its first segment of abdomen is yellow-brown in color while both end points are black. The second segment is black and in its middle part there yellow-brownish strips of V form, the peripheral part of which are found two spots of yellow brownish color. On third to fifth segments of male and on third to sixth segments of female there are fod-form spots, one on each segment, and on both sides of these rods two smaller spots are found in each segment. This species is clearly a fungus feeder and its breeding in authers laboratory is at present, not attained. Holotype : male , Kwang-nung, Kyung -gi Do, South Korea, 1 Male June, 1, 1961.
