The Freshwater Mussels (Unionoida) of the World (and other less consequential bivalves)
FM(U)otW(aolcb) is the web version of the MUSSEL Project Database. Follow the links to browse the data or use the custom Google search field. Either way, you win!
For each taxon, information is provided regarding habitat, horizon (Recent unless otherwise listed), and diversity. We are actively working on the Recent freshwater mussels, and those are the taxa for which the data are most complete. For other Recent freshwater bivalves, the information largely follows Graf (2013). For other taxa (e.g., marine, fossil), any content is largely incidental.

Bivalvia | Unionoida | Etherioidea family ETHERIIDAE Deshayes, 1832
6 nominal families as synonyms | cladomics
Global Distribution of the Etheriidae. The thin yellow wedge of the pie represents the Recent species diversity of the family (4 of 1015).
The Etheriidae is the least species rich of all six freshwater mussel families with only 4 Recent species. However, these species have a widely disjunct, Gondwanan distribution in Afrotropica, Neotropica and Indotropica. The monophyly of the family has been disputed.
