Microtus dukecampbelli C. A. Woods, Post, & Kilpatrick, 1982

Jackson & Cook (2020) proposed that the Florida population of Microtus pennsylvanicus be elevated to specific status as Microtus dukecampbelli (Woods et al. 1982).The work by Jackson & Cook (2020) is based on a cytochrome b (Cytb) analysis and the range map to the right represents the hypothesized range limit of Microtus dukecampbelli. Further studies will be needed to fully understand new species boundaries.

Description

From Jackson & Cook (2020): "In comparison with the nearest population of M. pennsylvanicus in Georgia, M. p. dukecampbelli is significantly larger (total length, tail length, hind foot length, greatest length of skull, condylozygomatic length, length of incisive foramen, length of diastema, cranial breadth, and zygomatic breadth) and has a shorter rostrum and darker coloration (Woods et al. 1982)."
