Diagnosis
ReferenceDiagnosis
K. P. Schmidt 1944 (Phyllemys barberi)The characters of the genus serve to distinguish the species from all known forms; the anterior border of the carapace is little emarginate, the pygal not notched or slightly, fenestrae between costal disk of carapace and peripherals large; shell notably thin and dense.
