Stock mislabelling and its impact on phylogenomic analysis in the Drosophila nasuta subgroup/species complex

In the course of our 28 de novo genome study of the nasuta-subgroup of the immigrans species group, we have come to suspect that several stocks acquired from the major stock centers may have either been mislabeled or mixed up in other ways. This is a short note to indicate which stocks these are, how they were diagnosed, and how an alignment and assembly free (AFAF) phylogenomic analysis sheds further light on what probably occurred.
