This individual was collected at CIMAR24 station Polygon 1B at a depth of 1917 m on the slope of the continental shelf, Los Lagos region. This female specimen matches the diagnosis for the family Cyatholaimidae with a multispiral amphid, it also partially matches the diagnosis for the genera Paralongicyatholaimoides as it clearly has an oesophageal bulb, a small buccal cavity without teeth, no obvious lateral differentiation. However it is lacking a filiform tail, the tail on this specimen is conical.

Pomponema tautraensis
This individual was collected at CIMAR24 station POL1A at a depth of 166 m on the continental shelf, Los Lagos region. This male specimen matches the diagnosis for Praecanthonchus with the exception of the tail which is is conico-cylindrical, with the cylindrical portion accounting for 50% of its length. This species has an obvious forward pointing dorsal tooth. The multispiral amphid is located just behind the buccal cavity. The cuticle is without lateral differentiation, but there are regular large pores. The spicule is curved with a clavate head, the gubernaculum has a squarish distal portion with teeth. There are 5 tubular precloacal supplements, and one very short postanal setae.
