If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L. M. Lambe 1906 | Supramarginal shields present in the carapace; mesoplastra well developed, in contact in the median line for some distance; intergular shield divided; inframarginal shields present on the bridges. | |
| O. P. Hay 1908 | Like Baena, but having on each side supramarginal scutes, which alternate with the costal scutes. Nuchal bone short and wide. A preneural present. | |
| E. S. Gaffney 1972 | 1) shell oval, sides roughly parallel; 2) ornamentation varied as in Baena; 3) nuchal scute much wider than long; 4) no anterior emargination; peripherals not meeting medially; 5) preneural bone present but much smaller than in Chisternon; 6) first vertebral scute roughly rectangular but anterior width invariably less than posterior width, paired lateral supracostal scute present; 7) supramarginal scutes present, usually three pairs; 8) last vertebral scute opening widely on posterior edge of carapace, scute width narrowing posteriorly due to presence of paired lateral supracostal scutes; 9) posterior edge of carapace slightly emarginated; 10) posterior edge of carapace scalloped; I 1) xiphiplastral notch absent; 12) paired intergulars meeting medially as do gulars. |
