Finding. Kashmir voles are not two species. Khan, Cannatella and colleagues sequence cytochrome b from northern Pakistan, fold it into 194 arvicoline tips, and get five Hyperacrius clades 12% to 14% apart. They call those species. H. wynnei swallows H. w. traubi. H. zygomaticus goes up in rank. One clade is tentatively H. brachelix. Two more are unnamed. External measurements only cleanly find H. wynnei (70.3% overall accuracy). The deeper mitochondrial story is tribal: nuclear genes take Hyperacrius off Clethrionomyini and sit it beside a Microtini-Arvicola-Lagurini-Dinaromys-Ellobiusini group, while mitochondrial trees only weakly nod at Ellobiusini. Alticola falls apart; A. macrotis cytochrome b lives inside Clethrionomys, which the authors read as mitochondrial capture.
Why this paper matters
This is rodent systematics with a mitochondrial marker, plus a mito-nuclear argument. Capture and tribal misplacement are the reasons a mitochondria site should mention it. If your database still parks Hyperacrius in Clethrionomyini, or treats Alticola as monophyletic, the tree is now a problem. If you wanted a vole OXPHOS paper, you opened the wrong DOI.
What they actually measured
New Cytb, a near-complete arvicoline genus sample, five analysis sets, likelihood, and a morphometric side analysis. Nuclear genes are used to relocate the genus. Mitochondrial data are used to split species and to wave at Ellobiusini. The capture claim is a nested-sequence inference.
How to read the score
Around 60. Real mtDNA systematics, no organelle phenotype. Confidence is medium for the undescribed clades and the capture story, higher for "not two species."
Caveats
Cytb distances are not a species law. Clades 3 and 4 are unnamed. Capture is likely, not proven. Morphometrics cannot separate the cryptic pair.
What to do with it
Update arvicoline mtDNA trees and Hyperacrius species counts. Recheck Alticola macrotis records for capture. Ignore this brief for disease or bioenergetics work.
