|---|---|---|
| M. Mlynarski 1969 | A small land species with a very strongly vaulted carapace, which has a characteristic conical shape, distinctly steep in the pygal region. Shields with visible sculpturing, separated by deep and clear sulci. Plastron broad, without mobile joints of plates. Gular region of plastron very clearly narrowed, epiplastral lips thick and fossa epiplastralis large and deep. Entoplastron large, distinctly elongated, without humeropectoral sulcus; anal notch triangular. Pectoral shields very narrow, much narrower than other shields of plastron. Gular region of carapace with two metaneurals and one postcentral, typical of the members of the genus. Praecentral shield narrow but distinct. Skeleton unknown. Length up to 220 mm. | |
