Diagnosis
ReferenceDiagnosis
T. Kimura and Y. Hasegawa 2024Differs from I. anillodefuego in: less telescoped cranium with anterior end of nasal locating anterior to level of antorbital notch and posterior end of nasal locating at anterior 1/4 of orbit; transversally narrower ascending process of premaxilla; ascending processes of maxilla and premaxilla extending further posteriorly to posterior end of nasals; more slender and elongate nasal bones; large exposure of parietal and/or interparietal on flat-topped intertemporal region; parietal broadly covers posteromedial part of supraorbital process of frontal; thickened knob-like anterodorsal part of parietal. Remarks. I. fordycei is placed in the genus Incakujira because of the following combination of characters: twisted postglenoid process; narrow, attenuated ascending process of the maxilla; well-defined external occipital crest; triangular protuberance on the supraoccipital; and lacking a squamosal crease (Marx and Kohno, 2016).
