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
ReferenceDiagnosis
O. P. Hay 1908Plastron in most cases suturally articulated to the carapace; with an entoplastron, but without mesoplastra; the anterior and posterior lobes usually reduced in size. Nuchal bone with or without costiform processes. Neural bones reduced in number, except in Baptemys; some of the hinder costal bones meeting their fellows in the midline, except in the same genus. Peripheral bones in 10 or 11 pairs. Plastron furnisht with a full series of inframarginal scutes, except in Basilemys. The scutes of the anterior lobe perhaps in all cases modified from the condition seen in Baina. Caudal vertebrae in all the known forms procoelous. The hinder lobe of the plastron often with a scar for the pelvis, but the latter never suturally joined to the plastron. Temporal region not rooft over and no parieto-squamosal arch. Quadrate notcht behind for the stapedial rod.
E. Perrier 1928Queue courte, moindre que la moitié de la carapace; tête complètement rétractile, grande, recouverte d'une peau non divisée en écailles, sauf un bouclier corné sur le nez ; carapace fortement déprimée, tricarénée, recouverte par des plaques cornées typiques; série des plaques osseuses neurales non continue, les costales postérieures se rejoignant sur la ligne médiane; plaques cornées du plastron séparées des marginales par des inframarginales. Tortues de marais, s'enfonçant dans la vase, vivant de poissons, de crustacés et de mollusques.
J. R. Bourque et al. 2015Plastron suturally united to the carapace;
entoplastron present (Appendix S1:Ch. 28); plastral lobes
reduced; nuchal with or without costiform processes; three to
five pairs of inframarginal scutes present (Appendix S1:Ch. 30)(Hay, 1908); temporal region emarginated from behind, separating
squamosal from parietal and postorbital; frontals enter
orbital margin; maxilla does not meet quadratojugal; quadrate
does not surround stapes; no foramen present in prootic for temporal
artery; dentary expanded posteriorly over much of external
surface of jaw; only one biconvex centrum in cervical vertebrae;
eighth centrum doubly concave anteriorly; caudal vertebrae procoelous;
paired pubes and ischia meet ventrally, but pubic and
ischiadic symphyses are widely separated; trochanteric fossa of
femur widely open (Iverson and Mittermeier, 1980); axillary buttress
contacts C1 (Appendix S1:Ch. 25) (Meylan and Gaffney,
1989); carapace smooth or with some crenulated sculpturing;
club-shaped terminus of axillary buttress; C3 spans P5 dorsally
(Hutchison and Bramble, 1981); distal C1 terminates in P3
(Appendix S1:Ch. 7); two suprapygals present (Appendix S1:Ch.
10); lack of distinct anterior musk duct groove (Appendix S1:Ch.
15); loss of extragular and pectoral scutes; marginals not
encroaching upon suprapygals or costals; abdominals contribute
to axillary notch (Appendix S1:Ch. 34); femoral–humeral sulcus
arched anteriorly; reduction or loss of foramen stapedio-temporale;medial triturating ridge of dentary curving laterally anteriorly
and contacting lateral ridge to form a pocket.
