Biodiversity and Phylogeny of North Atlantic Euphrosinidae (Annelida)
Euphrosinidae (Amphinomida) is a clade of generally small, short but stout annelids characterized by long, calcareous chaetae that may be distally forked or ringent. Little is known about the diversity of Euphrosinidae from the North Atlantic and the phylogeny of the group has received little attent...

Euphrosinidae (Amphinomida) is a clade of generally small, short but stout annelids characterized by long, calcareous chaetae that may be distally forked or ringent. Little is known about the diversity of Euphrosinidae from the North Atlantic and the phylogeny of the group has received little attention. Here, we examined 59 specimens of Euphrosinidae (primarily from the IceAGE I and II cruises) and sequenced fragments of the mitochondrial 16S rDNA and nuclear 28S rDNA genes to improve understanding of euphrosinid diversity in the North Atlantic and gain insights into euphrosinid phylogeny. Maximum likelihood analysis of 28S + 16S recovered Euphrosine as a ‘basal’ paraphyletic grade; a clade containing E. armadillo (plus other unidentified specimens) was sister to Euphrosinopsis + Euphrosinella while a clade containing E. aurantiaca and E. foliosa (plus three unidentified species) was recovered sister to all other sampled Euphrosinidae species.
