A region of approximately 1.6 kb encompassing the ribosomal protein 49 gene (rp49) has been sequenced and compared in nine species of the obscura group of Drosophila: four species belonging to the obscura subgroup, three to the pseudoobscura subgroup, and two to the affinis subgroup. Our data provide strong support that the nearctic species (pseudoobscura and affinis subgroups) are monophyletic and place D. bifasciata with the other species of the obscura subgroup. Nucleotide sequence information at the rp49 gene region (located very close to one of the breakpoints of inversion O3) has also been used to infer the phylogeny of the O chromosome in the subobscura species cluster. Analysis based both on parsimony-informative sites and on genetic distances confirms that the O3 gene arrangement, present in D. guanche (together with inversion g) and in D. madeirensis, is ancestral to gene arrangements O3 + 4 and Ost present in extant populations of D. subobscura.
