This research is the result of polytene chromosome analysis in Drosophila sp. nov. Cytological plaques and maps were made from salivary glands of 18 third-stage larvae. Six inversions corresponding with Primitive I were found in this species’ chromosomic sequence: Xa, Xb, Xc, 2a, 2b and 3b, localized in chromosomes X, 2 and 3. Chromosomes 4, 5 and 6 show a conserved sequence similar to the hypothetic Primitive I. Besides Primitive I, there was no evidence for paracentric inversion in the banding pattern of polytene chromosomes of this species. These results suggest that Drosophila sp. nov. is a primitive species of the replete group and may have given origin to other species within this group.
