FIGURE 10. Anterior portion of braincase in lateral view of A: Akodon diauarum n. sp. (MN 73906), B: A. paranaensis (MZUSP 29094), and C: A. montensis (UFMG 2695). Abbreviations: fps, frontoparietal suture; Fr, frontal; fss, frontosquamosal suture; lpp, lateral projection of the parietal; Pa, parietal; Sq, squamosal. Note that the frontosquamosal and the frontoparietal sutures are mostly colinear in A. montensis and A. paranaensis, but form an acute angle (approximate 90º) in Akodon diauarum n. sp., presenting an area of contact between the dorsal facet of frontal and squamosal (white arrow); and the lpp highly and moderately developed in Akodon diauarum n. sp. and A. paranaensis, respectively, but absent (or inconspicuous, when present) in A. montensis. Figures are not to scale to facilitate comparisons.
