Redescription of <i>Helmetophorus rankini</i> Hartman, (Polychaeta: Helmetophoridae) and its transfer to the Flabelligeridae
Proceedings of the Biological Society of Washington
The only representative of the Helmetophoridae, Helmetophorus rankini Hartman, 1978, is redescribed and transferred to the Flabelligeridae. The species shares in common with the Flabelligeridae a papillated body surface, a buccal region with branchiae and grooved palps that is covered (partially)by a cephalic hood, weakly developed parapodia, and cross-barred capillaries.
