Diagnosis. Body U-shaped, approximately cylindrical, may exceed 30cm in length. Color uniform to variegated light reddish brown. Tentacles 20 in 2 rings, 5 large pairs in outer ring alternating with 5 small pairs in inner ring. Body wall ossicles square tables (66 µm in length), commonly with 4 to 8 perforations, of which 2 are larger than others; spire reduced to form 4 vertical projections. Introvert and tentacles with tables and rosettes.

Distribution. Gulf of Mexico, NC to E FL.

Habitat. sublittoral; offshore in soft sediment. 6– 158 m.

Remarks. Miller and Pawson (1984:36), in their discussion of Phyllophorus (Urodemella) occidentalis ( Ludwig, 1875) from the Gulf of Mexico, noted that this species occurred off eastern Florida. Further study showed that the eastern Florida specimens represented a new species described later as Phyllophorus (Urodemella) arenicola Pawson & Miller, 1992 .
