Diagnosis
ReferenceDiagnosis
R. M. Hunt 2011Differs from T. altigenis and T. subferox in larger size and from T. macrogenys in much smaller size. Distin- guished from T. ferox by taller differently proportioned p3–4 and by dimensions of m1– 2 and M1 that together exceed the size attributable to a T. ferox population (ta- bles2, 3). T. percussor differs from T. fingeruti in having a taller more robust, somewhat longer p3–4, shorter m1–2, and no m2 metaconid. M1 lingual cingulum better developed in T. percussor relative to T. fingeruti.
