Phylogenetic position of the enigmatic genus Atherospio and description of Atherospio aestuarii sp. nov. (Annelida: Spionidae) from Japan.

ABSTRACT:

Background

There are currently two species within the small enigmatic genus Atherospio Mackie & Duff, 1986, which belongs to the Pygospiopsis-Atherospio group in the family Spionidae Grube, 1850. The taxonomic relationship of the genus Atherospio with other spionid or spioniform genera is currently not well understood due to its unusual morphological characteristics.

Methods

Here, we describe a new Atherospio species, Atherospio aestuarii sp. nov., based on materials collected from three localities in Japan: Hirota Bay (Iwate Prefecture), Ago Bay (Mie Prefecture), and Yakushima Island (Kagoshima Prefecture). We have also evaluated the possible systematic position of this new species by conducting molecular phylogenetic analyse
