Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. J. Horný 2006 (Pygmaeoconinae) | Small cap-shaped, thick-shelled cyrtonellids adapted for stationary life on hyolithid conchs. Apertural margin cradle-like, with lifted anterior and posterior margins to fit with the hyolithid dorsum. A set of discrete muscle scars parallel with the apertural margin relocated by saltation. External surface with crowded thin growth lines interrupted by periodically repeating intervals of reduced rate of shell secretion corresponding to relocation of muscle attachments. |
