Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| Z. Qiu 2006 | Plesieomys differs from Eomys Schlosser, 1884 in having a cuspidate enlargement at the end of mesoloph on upper molars; longitudinal crest in the upper cheek teeth being situated more lingually, in the lowers more labially; and in more lingual extension of the 1st and 4th synclines in M1 and M2.
Plesieomys differs from Eomyops Engesser, 1979 and Leptodontomys Shotwell, 1956 in larger dimensions ( except E. hebeiseni) ; having an enlarged end of the mesoloph on upper molars; and a much less distinct lingual anteroloph of M1 and M2. Plesieomys differs from Pentabuneomys Engesser, 1990 in having smaller dimensions and lacking an enlargement of mesocone( id) ; weaker development of lingual anteroloph on Ml and M2; more reduced M3 and m3. Plesieomys differs from Pseudadjidaumo Lindsay, 1972 in having an enlarged termination of the mesoloph and a weaker development of the lingual anteroloph on M1 and M2, and a weaker anterolophid and hypolophid on ml and m2; more rapid changes of the anterolophid and posterolophid with wear in lower molars. Plesieomys differs from Ronquillomys Jacobs, 1977 in smaller dimensions with more pronounced anterolophids on the lower molars; having a deeper 1st syncline on the M1 and M2, a broader 4th syncline on the lower molars; longitudinal crest situated more lingually in the upper cheek teeth, more labially in the lower cheek teeth; lower molars less narrow posteriorly than anteriorly. Plesieomys differs from Kansasimys Wood, 1936 in smaller dimensions; having a deeper labial syncline in the upper cheek teeth and a deeper lingual syncline in the lower cheek teeth; hypolophid directed posteromedially from the entoconid rather than anteromedially. |
