Beck <i>et al.</i> (2022) list the following cranial and dental features as diagnosing <i>Acrobates</i> from <i>Distoechurus</i>: differing cranially in having a proportionally larger and more inflated neurocranium, a proportionally shorter and deeper rostrum, a vertically expanded sphenorbital fissure; a deep sulcus that houses the transverse canal vein extends laterally from the carotid canal and is floored ventrally by a strut of the alisphenoid vs by the posterior part of the pterygoid in <i>Distoechurus</i>, a narrower mandibular angular process; differing dentally in having P 3 relatively large and subequal in size to P 1 (reduced in <i>Distoechurus</i>), M 1-2 square rather than triangular, with the protocone positioned lingual to the paracone, and with more prominent buccal cingula, M 3 relatively large, more than one half the occlusal area of M 2 (Fig. 6).</p>
