text: The Dulzura kangaroo rat was at one time thought to be conspecific with the agile kangaroo rat (Dipodomys agilis) but the two are now recognised as being separate species; there is significant differences between them in their morphology, and their chromosome counts differ, with D. agilis having a karyotype of 2n=62 and D. simulans having 2n=60.
