Key to genera of aperturally dentate Charopidae in southern Africa

1. Protoconch with fine, but well-defined, crisp, axial riblets ............................................................... 2

– Protoconch smooth or micro-shagreened; lacking crisp, axial riblets (at most with low, indistinct, radial undulations). ............................................................................................................................ 4

2. Protoconch with only axial riblets, spiral sculpture lacking; eastern South Africa........................... 3 – Protoconch with both spiral threads and axial riblets; W. Cape .......................... Iterodonta gen. nov.

3. Spire deeply sunken, teleoconch sculpture of widely-spaced axial riblets with numerous intermediary axial threads .............................................................................................. Biomphalodonta gen. nov.

– Spire flat or slightly raised, teleoconch sculpture of close-set axial riblets with fewer intermediary axial threads .................................................................................................... Costulodonta gen. nov.

4. Spire deeply sunken, shell markedly biconcave; Amathole Region of E. Cape. ................................. ...................................................................................................................... Amatholedonta gen. nov.

– Spire elevated, flat or at most shallowly sunken ................................................................................ 5

5. Teleoconch sculpture of fine but distinct compound axial riblets with multiple intermediary axial threads; umbilicus wide to very wide ............................................................... Phialodonta gen. nov.

– Teleoconch silky, sculptured by simple axial riblets usually of alternating strength; umbilicus narrow to moderate ................................................................................................................ Afrodonta s. str.
