Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| X. Shi et al. 2022 | Annulated worm-like body with an anterior armoured proboscis, an elongate trunk of consistent width and terminal posterior hooks. Anterior proboscis divided into three sections from proximal to distal: introvert with circumoral longitudinal rows of spines ( presumed scalids); collar region with or without spines; and pharynx covered in rings of pharyngeal teeth. Introvert at least partially retractable into the trunk, pharynx elongate and fully eversible. Posterior terminal hooks arranged bilaterally about the sagittal plane of the trunk. |
