The taxonomy of the genus Cricetulus has been controversial. The phylogenetic relationships both within the genus and among Cricetulus lineages and other genera were examined using a set of five nuclear and two mitochondrial genes. The results demonstrate that Cricetulus in its current treatment is a polyphyletic assemblage because the subgenus Urocricetus is phylogenetically unrelated to all other Cricetulus and is a distant sister group to Phodopus. The grey hamster (C. migratorius) proved to be closer to Cricetus and Allocricetulus than to Cricetulus proper, which includes C. barabensis C. sokolovi and C. longicaudatus. Based on these results Urocricetus is elevated to the rank of a full genus and a new genus Nothocricetulus gen.nov. is described for the grey hamster.
仓鼠属的分类一直存在争议。利用一组五个核基因和两个线粒体基因，研究了仓鼠属内以及仓鼠属谱系与其他属之间的系统发育关系。结果表明，当前分类中的仓鼠属是一个多系类群，因为仓鼠亚属在系统发育上与所有其他仓鼠属无关，并且是毛足鼠属的远亲姐妹类群。事实证明，灰仓鼠（黑线仓鼠）与仓鼠属和白腹巨鼠属的关系比与狭义的仓鼠属（包括黑线仓鼠、索氏仓鼠和长尾仓鼠）更近。基于这些结果，仓鼠亚属被提升为一个完整的属，并为灰仓鼠描述了一个新属——新仓鼠属。
