Size: 20-300 mm by 2 mm.

Body stout a little flattened; 80-90 segments. Prostomium broader than long. Four black eyes. Palps stout, divergent as long as the tentacles. Longer tentacular cirri reaching backwards to the 4th or 5th segment. Jaws dark, curved, smooth on edge. Maxillary ring with small conical denticles, transparent, hardly visible. Dorsal ramus with 3 ligules, the upper triangular, with well marked dark glands; the two lower ligules subequal, conical, smaller; dorsal cirrus on the base of the superior ligule and a little longer. Ventral ramus with two unequal fillets and a slightly longer, blunt, ligule; ventral cirrus tapering, shorter. In the posterior region, dorsal ramus much longer than the ventral. Dorsal setae all homogomph spinigers. Ventral setae, in the anterior and posterior feet, homogomph and hemigomph spinigers and shorter heterogomph ones. On the middle region from about the 13th and 15th setigerous segment, the ventral heterogomph spinigers are superseded by falcigerous setae the terminal piece of which has a spinous convex edge and an enlarged and abruptly truncated tip. Event in the posterior feet, there are no dorsal falcigerous setae and the ventral falcigerous setae are absent, in the anterior and posterior feet. Two long anal cirri.
