Two different species which were originated from India and Indochina have been called Drosophila jambulina as the same species. They were compared genetically, cytologically and electrophoretically, as well as morphologically. From these results it was concluded that the Indian species was the realD. jambulinaand that the Indochinese species seemed to be a new species and was tentatively namedD. punjabiensis-likebecause it was closer to the sibling species, D. punjabiensis. D. jambulinashowed a color dimorphism in a terminal tergite of female. A light-type gene controlling the dimorphism was dominant over a dark-type gene. The heterozygote segregated into 3 light: 1 dark in the next generation.
