Molecular evidence for ParaPhyly in Nyctomys sumichrasti: SuPPort for a new GenuS of veSPer Mice? Megan S. Corley, niCté ordóñez-garza, duke S. rogerS, and robert d. bradley abStract DNA sequences were obtained from the mitochondrial cytochrome-b gene of nine speci- mens of Nyctomys sumichrasti collected in Mexico and Central America. Phylogenetic analysis (Bayesian Inference) of these sequences document heretofore unrecognized patterns in genetic diversity among phylogroups that: 1) indicated substantial levels of genetic divergence among phylogroups; 2) resulted in paraphyly of taxa currently recognized as N. sumichrasti; and 3) argued for a re-assessment of the current taxonomy of Nyctomys
