| The sessile amoeba is encased in a hyaline, flattened lorica, which holds the MCB and connects to the meroplasmodium. |
| The animal is attached, as in the closely allied genus Tintinnus, by a peduncle to the bottom of the lorica. |
| The animals are similarly fastened to the lorica, sometimes directly, sometimes by means of a short stalk. |
| Sometimes the mouth becomes twisted and the lorica is therefore bilateral. |
| The lorica is swollen posteriorly, narrowest at the oral margin, bent on its axis and is supported on a short stalk. |
| Stiff cuticles are simple to recognize, and loricate genera can often be recognized based upon lorica shape alone. |
