This is to confirm that the Drosophila littoralis fosmid sequences and gene annotations in my Bergman et al. 2002 Genome Biology paper (PubMed ID 12537575) are actually Drosophila virilis based on their subsequently determined sequence identity to the aligned regions of the Drosophila virilis WGS assembly. While there was some initial taxonomic classification confusion on this, we believe our conclusion is clear. Thus, the 8 Drosophila virilis fosmid sequences linked to Bergman et al. (accessions AY190943, AY190952-AY190956, AY190958, AY190963) are correctly marked as D. virilis in those GenBank records and the linked CDS/protein accessions.
