Fig. 9.—Selected anatomical features of the skull of Akodon philipmyersi (CNP 3029—left and upper specimen) and A. kadiweu n. sp. (MZUSP 35767—right and lower specimen). (A) rostral and palatal region in ventral view; (B) rostral region in lateral view; (C) anterior portion of braincase in lateral/oblique view; (D) rostral region in dorsal view; (E) posterior portion of palate region and mesopterygoid fossa in ventral view. Abbreviations are: fps, frontoparietal suture; Fr, frontal; fss, frontosquamosal suture; if, incisive foramen; ms, mesopterygoid fossa; Na, Nasal; nc, nasolacrimal capsule; Pa, parietal; pt, parapterygoid fossa; Sq, squamosal; zn, zygomatic notch; zp, zygomatic plate. White-dotted (A, B, and C) and white bars (E) indicate comparative alignments. Note the length of the white bars of the mesopterygoid and parapterygoid fossae, similar in A. philipmyersi but different in A. kadiweu n. sp. (E). Figures are not to scale to facilitate comparisons. Note that the frontosquamosal and the frontoparietal sutures are colinear in A. philipmyersi but form an approximate 90° angle in A. kadiweu n. sp., presenting an area of contact between the dorsal facet of frontal and squamosal (C.).
