Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| I. G. Danilov et al. 2002 | A turtle with a shell of 20 – 30 cm length. Shell bones thick. Nuchal emargination weak. Nuchal plate with a transverse thickening passing
into the anterior peripherals. First neural shortened. Free margin of anterior peripherals upraised. Buttresses moderately developed (intermediate between conditions in Mongolemys and Lindholmemys. Inguinal buttress attaches along the posterior border of the costal V. Trace of the first thoracic rib shortened. Plastral proportions as in Mongolemys. Cervical scale relatively small, square. First vertebral scale widened anteriorly with a waist in its anterior part, overlaps first peripherals but does not reach second marginals. Last pair of marginals low. Three (?) pairs of elongated inframarginals. Their width is about 25% of the half of the plastron width. First inframarginal covers about half of the bridge part of hyoplastron. Shell surface sculpture consists of pronounced tubercles and ridges. |
