Abstract
D. bipectinata and D. malerkotliana differ from each other by three overlapping inversions in IIL, two included inversions in IIIL and two overlapping inversions in IIIR. These inversions were analysed on the basis of the salivary chromosome maps of D. malerkotliana. Bock's (1971) data revealed that the four members of the bipectinata species complex differ from each other with respect to overlapping inversions. The reason why the ancestral population which may have been heterozygous for common inversions split into at least four groups, each leading to the formation of a new species, and the possible mechanism of the origin of sexual isolation between the groups is discussed.
