is likely a juvenile but has several unique characters not found heretofore in the genus: (1) the pre-setiger region is large, oval-shaped, and longer than the first five setigers, (2) setigers 1–2 entirely lack notopodial postsetal lobes; then long, digitate fully developed postsetal lobes appear on setiger 3 and continue along the entire body, (3) the furcate setae have unequal tynes that terminate in narrow, pointed tips. Most orbiniids have furcate setae with blunt-tipped tynes. While the presence of emergent and prominent aciculae in abdominal neuropodia is typical in the genus,

The lack of specimens of this species is surprising given the long timeframe of benthic studies along the US Atlantic coast. However, the species was collected from sediments having high sand content and these non-depositional sediments are not routinely sampled as part of offshore monitoring and reconnaissance programs.

Prostomium pointed on anterior margin. Peristomium consisting of a single achaetous ring. Transition from thorax to abdomen abrupt due to distinct change in neuropodia. Branchiae from setiger 8–10; each branchia simple, lanceolate, may be lacking in most of abdominal region. Thoracic setae all capillaries; abdominal setigers 1–3 (rarely 4) with dense fascicles of thickened uncini in neuropodia and none to a few capillaries; subsequent thoracic neuropodia usually with all capillaries; one species with a few thin uncini and capillaries continuing to end of thorax. Neuropodial uncini of setigers 1–3 with shafts either smooth or with ribs; tip of shaft with distinct sheath, often frayed, appearing bristled in light microscopy. Neuropodia with or without postsetal lobe; subpodial lobes absent. Abdominal segments lacking interramal and ventral cirri. Abdominal setae including capillaries, furcate setae, and flail setae; no uncini. Pygidium a rounded lobe with two anal cirri.

The heavy spines provide setigers 1–3 with a different appearance relative to the subsequent thoracic segments that have only capillaries or only a few similar spines. Pettibone (1957) noted that a few transitional spines were sometimes present among the capillaries of the unmodified setiger 4 of
