Abstract
Two European species, Drosophila subobscura and D. ambigua, have been found in the Pacific Northwest. Drosophila subobscura occurs from central California, N to southwestern British Columbia. Drosophila ambigua has been found only in the southwestern mainland of British Columbia. These species can be distinguished from the endemic obscura-subgroup species, D. pseudoobscura, D. persimilis and D. miranda, by sex comb, vaginal plate and wing bristle morphology, by allozymic differences and by differences in the polytene chromosomes.This publication has 4 references indexed in Scilit:
