). Pelagic in oceanic waters. Carapace cylindrical to globose, tapered anteriorly in some species. The posterior dorsal corner is unarmed, and either smoothly rounded or obtusely angled. Posterior ventral corner is rounded. Carapace lacks sculpture in the majority of species, but when present is either in the form of longitudinal striae or concentric rings. RAG on posterior margin close to posterior end of hinge between carapace valves. LAG on dorsal face usually posterior to rostrum but always anterior to midlength. Labrum with a deep V-shaped cleft.

genera by the positions of the asymmetrical glands on the carapace valves. The LAG opens on the dorsal margin in the anterior half of the carapace usually just posterior to the anterior end of the hinge between the two carapace valves. In several of the newly designated genera, the LAG opens closer to mid-length, but in one genus, it opens in front of the anterior end of the hinge (i.e. on the rostrum). The RAG opens on the posterior margin, usually close to the posterior end of the hinge and near the rounded posterior dorsal corner of the carapace. However, in some genera the RAG opens lower down the posterior margin sometimes at the apex of a shallow angle.

There are often only subtle intergeneric and interspecific differences in the morphologies of the limbs, so confirming the identities of specimens is seldom easy. There may be slight variations in the external appearances of species that clearly have very different ecologies. Preliminary results of barcoding the CO1 gene of some of these species have confirmed their separate identities (
