| Redescription | |
| Scientific Name Notes | This species was described for specimens identified as lecanicephalidean larvae from a pearl oyster. Jameson also described an adult worm from "Aetobatis narinari" from Shipley's material which he considered to be "in all probability the adult of this larva". This species is essentially unrecognizable based on its original description and is therefore considered a species inquirenda. |
