In the present study, we formally describe two new species of
ย from ท.
The most abundantone belongs to the subfamily ย, but based on morphological
characteristics the species could not be further identified
to any hitherto described genera, and consequently a new
genus has been proposed. The other ampharetid species found at
ท is described as a new species of ส , a genus originally described from cold seeps
in the Sea of Okothsk, NW Pacific. The genus ส was considered
a junior synonym to ย but is here recognized as a valid genus, now containing two
species. An emended diagnosis of the genus ส is provided.
