but differs most noticeably in the number of thoracic and
abdominal chaetigers. In P. schanderi gen et sp. nov., 15 thoracic and
up to 20 abdominal chaetigers are present compared to 20 thoracic
and up to 12 abdominal chaetigers in specimens identified as Paramytha
sp. from Setúbal Canyon. The inclusion of the specimens from
Setúbal Canyon as a separate species in Paramytha is supported by
molecular data (see Section 3.1).
