Ordination of Ctenomys pulcer sp. nov., Ctenomys bidaui, Ctenomys magellanicus fueguinus, Ctenomys magellanicus dicki and Ctenomys magellanicus LB in the morphospace defined by the first two principal components of the aligned Procrustes coordinates (APC) of ventral view of cranial shape variation. Shape changes associated with positive and negative values of both axes are shown as wireframes: black dots and lines indicate shape changes with respect to the mean configuration indicated with orange dots and lines. Abbreviations: H, holotype; LB, Lago Buenos Aires County (Santa Cruz, Argentina).
