In their 2006 seminal paper on the genetic criteria in species delimitation in mammals, Baker & Bradley observed that “genetically distinct populations … are distributed much like that implied in typical subspecies maps”. Indeed, species are structured morphologically and genetically, but little attempt has been made to assess the concordance, or lack of it, between patterns retrieved by different data sets. By sampling the edible dormouse Glis glis (Linnaeus, 1766) throughout its known range we explored the consistency among divisions produced by mitochondrial cytb sequence and geometric morphometric variation of skull and mandible. The match was perfect what gives us confidence that in our case the mitochondrial lineages are meaningful units for conservation management. Our study would not be possible without vouchers deposited in public museum collections. Over-impressed by recent advances in molecule-based techniques we are frequently too ignorant for the future of museum collections. As was repeatedly demonstrated over the last years, collections are declining in many countries due to neglect, ignorance, and lack of funding.
