Diagnosis. Threadlike body, 5–6.5 mm long and 0.2–0.3 mm wide measured in the third chaetiger, with about 48–56 chaetigers. Prostomium conical, without eyes or appendages ( Fig. 5A View FIGURE 5 ). Peristomium biannulate ( Fig. 5A View FIGURE 5 ); parapodia biramous with 2–7 capillary chaetae on each rami and at least 1 bidentate hook ( Fig. 5C View FIGURE 5 ). Up to 15 pairs of branchiae posteriorly, consisting of simple cirriform appendages increasing in length towards the pygidium ( Fig. 5B View FIGURE 5 ). Pygidium with two pairs of short anal cirrus (dorsal and ventral). Segments modified at sexual maturity all have at least one type of chaetae (capillaries, hooks, or both), including chaetigers 12–14. Two oocytes recorded in chaetigers 10–13 of mature females ( Fig. 5A View FIGURE 5 ), and in anterior chaetigers 6–11 masses of glandular tissue ( Fig. 5A View FIGURE 5 ); males have chaetae reduced in size in chaetigers 12–13, with a slit-like dorsal fold.

Distribution. West coast of North America (California, British Columbia), Gulf of Mexico (west coast of Florida) ( Giere & Erséus, 1998). Mediterranean Sea ( Somaschini & Gravina, 1993) and Macaronesian region (Azores and Canary Islands). The species is recorded for the first time from the Azores.
