Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. Marigó et al. 2013 | Medium-sized anchomomyin larger than most Anchomomys and smaller than Mazateronodon, Periconodon, and Buxella. Also smaller than the sivaladapids Hoanghonius and Rencunius, and the asiadapine Asiadapis, and similar in size to the asiadapine Marc- godinotius. It presents no wrinkled enamel unlike Buxella magna and Periconodon jaegeri. Its buccolingually compressed P4 re- sembles no other anchomomyin, Asiadapis or Rencunius. Upper molars with no pericone unlike Anchomomys pygmaeus, Buxella prisca, Periconodon, Hoanghonius, and Rencunius, medium-sized hypocone similar to that of Anchomomys quercyi and Mazater- onodon, larger than in Marcgodinotius and Asiadapis, and smaller than in Periconodon and Buxella, straighter postcingulum than most Anchomomys, Marcgodinotius, Hoanghonius, and Rencunius. It also presents an extremely reduced metacone in the M3 unlike any other anchomomyin and Marcgodinotius, a shorter anterocingulum than Anchomomys, Mazateronodon, Periconodon, Asiadapis, Hoan- ghonius, and Rencunius, and no lingual cingulum in the upper molars unlike Anchomomys, Buxella, Hoanghonius, and Rencunius.
Lower premolars with no paraconid unlike most Anchomomys, and discontinuous buccal and lingual cingulids unlike all other ancho- momyins. Lower molars with no paraconid unlike most Anchomomys, Buxella, Periconodon jaegeri, the asiadapines Asiadapis and Marcgodi- notius, and the sivaladapid Rencunius, and presenting a premetacristid joining the paracristid and the metaconid, closing the trigonid basin, unlike any other anchomomyin but Mazateronodon, and also unlike Rencunius and the asiadapines Marcgodinotius and Asiadapis |
