Abstract:
Holothurians of the family Psychropotidae are widely distributed but remain the least studied deep-sea holothurians. On an expedition to the Western Pacific, six psychropotid specimens were collected by the Jiaolong Human Operated Vehicle (HOV). Through morphological examination, four of them were identified as a new species, Benthodytes jiaolongi sp. nov. , which was characterized as having minute papillae, a narrow brim, and a terminal anus; and the ossicles were rods and primary crosses. The remaining two specimens were identified as Psychropotes verrucicaudatus Xiao, Gong, Kou & amp; Li, 2019, first recorded at the Kyushu-Palau Ridge. The phylogenetic analysis showed that B. jiaolongi sp. nov. and P. verrucicaudatus were embedded in the clades Benthodytes and Psycheotrephes , respectively, and that Benthodytes was paraphyletic. The new species clustered with Benthodytes sanguinolenta and was separated from the clade containing the other Benthodytes species.
