Anguillosyllis, Day, 1963

Maciolek, Nancy J., 2020, Anguillosyllis (Annelida: Syllidae) from multiple deep-water locations in the northern and southern hemispheres, Zootaxa 4793 (1), pp. 1-73 : 70

Anguillosyllis sp.

Material examined. Abyssal Pacific, Clarion-Clipperton Fracture Zone. Coll. Dwight D. Trueblood for NOAA. Sta. 4-94, 12 o 55.967′N, 128 o 35.758′W, 4851 m, 1 specimen ( USNM 1480276 ) .

Remarks. This single nine-setiger specimen is in poor condition, with significantly decomposed tissue that precludes a full description. However, it is recognized as unique because of the combination of characters that distinguish it from other Anguillosyllis species with nine setigers (i.e., A. enneapoda n. sp., A. inornata n. sp., and A. pupa ). It has large posterior lobes that are lacking in A. enneapoda n. sp. and A. inornata n. sp. and differs from A. pupa in having more obviously pointed fused palps and other details of the parapodial lobes. Large eggs are present in setigers 6 and 7. It is also found in very deep water (4851 m) compared with the other three species.
