Description. A moderately-sized species, 11–15 mm long, 0.4–0.5 mm wide for 95–105 setigers. Body long, thickened throughout with narrow, crowded segments. Body dorsoventrally flattened with narrow ventral groove; typically coiled in preservation. Longitudinal muscles apparent along medial dorsal surface. Color in alcohol light tan to brown; no obvious pigmentation except dark internal area in prostomium, possibly indistinct nuchal pigmentation.
Pre-setiger region as long as first eight setigers. Prostomium unusually long, narrow, tapering to pointed tip ( Fig. 8A–E View FIGURE 8 ); eyes absent; nuchal organs elongate lateral slits on posterior lateral margin. Peristomium enlarged, an achaetous single ring with one or two lateral grooves not crossing dorsum; surmounted by prominent dorsal crest extending from posterior margin of prostomium to setiger 1. Dorsal tentacles arising from posterior margin of peristomium; first pair of branchiae located posterior and lateral to tentacles; second pair of branchiae dorsal to notosetae, continuing throughout. Dorsal tentacles thick with ciliated groove; branchiae long, thin.
Parapodia of anterior setigers reduced to low rounded lobes, becoming low vertical ridges on segments with hooks; noto- and neuropodia widely separated. Notosetae of anterior setigers 4–6 thickened capillaries; bidentate hooks first present from setiger 13–14, with capillaries reduced to a single threadlike seta or entirely absent; up to two hooks per notopodium. Neuropodia with a single bidentate hook from setiger 9–10, increasing to two hooks per fascicle in posterior segments with single threadlike capillary. Hooks of noto- and neuropodia directed toward each other vis-á-vis; hooks with shaft curved on concave side; main fang with apical tooth narrow, short, hood absent ( Fig. 8G–H View FIGURE 8 ).
Posterior end narrow, tapering; pygidium with two short anal cirri ( Fig. 8A, I View FIGURE 8 ).
Methyl Green staining. Body stains uniformly; anterior half of prostomium not staining.
Remarks. Caulleriella venefica , an offshore shelf species, is most similar locally to C. nobska n. sp., a nearshore species. Both species share a pointed prostomium, an elongate peristomium with a dorsal crest, and bidentate hooks that lack a hood or sheath. However, the prostomium of C. venefica is longer, narrower, and more acutely pointed than that of C. nobska n. sp. Caulleriella venefica has maximally two instead of three hooks in posterior neuropodia and there are two anal cirri instead of none. In addition, the bidentate hooks of C. venefica have the main fang at a more acute angle than the 45° angle observed in C. nobska n. sp. Caulleriella venefica has a single thin capillary seta accompanying the hooks in middle and posterior setigers instead of these being entirely absent in C. nobska n. sp. The additional records recorded here suggest that the species is widespread throughout the northeastern United States in continental shelf depths having sandy sediments.
Biology and Habitat. On Georges Bank, Caulleriella venefica inhabits sediments having98–99%sand, consisting of primarily very coarse to medium-sized sand particles (Maciolek et al. 1985). The long pointed prostomium and narrow elongate body suggest that the species is adapted to burrowing through these larger sediment particles. Other specimens examined as part of this study are also from sediments having high sand inventories.
Distribution. Northeastern US continental shelf, 35– 145 m.
