Title

Scytalium herklotsi sp. nov. (Anthozoa, Octocorallia, Pennatulacea), the first Atlantic species in the genus Scytalium Herklots, 1858

Abstract

A new species of the sea pen genus Scytalium Herklots, 1858, is proposed based on the morphological and molecular study of a colony collected during the Océano Profundo 2018 cruise to the Caribbean Sea (NW Atlantic). The new species, Scytalium herklotsi sp. nov., is characterized by its well-developed and overlapping polyp leaves (up to 68 mm in length and 27 mm in width), the presence of eight spiculated large digitiform processes at the distal part of the basal portion of autozooids, the axis rounded in cross section, the numerous siphonozooids in a continuous band of 3–6 rows along the latero-dorsal area of the rachis, and up to 3 rows between contiguous polyp leaves, among other features. An additional unrecorded type of sclerites is reported from the pharynx of autozooids, probably also present in other species of the genus. Scytalium herklotsi sp. nov. is the first species of the genus recorded so far from the Atlantic Ocean, all other described species being Indo-West Pacific. The new species is also the deepest record of a Scytalium species (ca 500 m in depth); the previous published records range from 10 to 206 m in depth. A molecular comparison based on a set of concatenated sequences of four markers (three mitochondrial genes (mtMutS, ND2, and Cox1) and a nuclear segment (28S)) relates the new species to other published sequences attributed to Scytalium species, within the named Clade II of previous general phylogenetic studies on the octocoral Order Pennatulacea.
