FIGURE 6 in Rediscovery of Juliomys pictipes (Rodentia: Cricetidae) in Argentina: emended diagnosis, geographic distribution, and insights on genetic structure

FIGURE 6. Selected cranial traits in adult (except noted) Juliomys pictipes (CIES-M 23). A. Rostrum in dorsal view: note the inconspicuous zygomatic notches and broad zygomatic root; B. Interorbital region: the arrow indicates incomplete fusion in the anterior part of the interfrontal suture; C. Interorbital region in a juvenile specimen (CNP 895); D. Rostrum in lateral view: note the almost absence of upper free border in the zygomatic plate; E. Interfrontal depression; F. Mesopterygoid fossa; G. Palatal and postpalatal region of a juvenile specimen (CNP 895): note the complete ossification of the mesopterygoid fossa roof; H. Temporal region; I. Braincase; J. Auditory capsule: note the extension of the meatus; K. Squamosal-alisphenoid region; L. Upper first molar detail: note the crested corona and the well developed mesoloph.
