Drosophila lacertosa and D. sordidula are members of the robusta species group in virilis section of Drosophila. The mtDNA of both species was analyzed, using 10 restriction endonucleases. The mtDNA genome size of D. lacertosa and D. sordidula was 15.7 kbp, altogether, and the numbers of mtDNA fragment were 26 and 32, respectively. Restriction cleavage map of mtDNA in these species was constructed. The patterns of cleavage map were very different between two species and it means that speciation was taken for a long time ago.

The chromosomes of thirteen wild forms of Drosophila obtained from Kwangnung in Kyunggi Province, Korea were investigated with the ganglion cells of both male and female larvae using the aceto-lactic orcein squashed method. The male chromosome patterns of the species observed in the present study are summarized as follows:
