We analyze phylogenetic relationships among temperate, subtropical highland, and subtropical lowland species of the Drosophila takahashii and montium species subgroups based on sequence data of COI and Gpdh genes and discuss the evolution of temperate species in these subgroups with reference to the

β¦ Synopsis
The aUozymic variations of five enzyme systems were examined by starch gel electrophoresis in six species of the Drosophila montium subgroup. This subgroup is characterized by peculiar acid phosphatase (Acph) and alkaline phosphatase (Aph) patterns in comparison with the Acph and Aph patterns of D. melanogasrer. Determinations of the percentages of the common allozymic bands among the six species reveals a range of values from 15.4% to 66.6%. The data indicate that D. kikkawai and D. serrata are very closely related species. The genetic similarity observed among the species D. auraria, D. biauraria and D. triauraria is far less than that observed in the case of D. kikkawai and D. serrata. Finally, D. tsacasi is probably closer to D. kikkawai and D. serrata than to D. auraria, D. biauraria and D. m'auraria.
