Specimens light tan in spirit with epidermal pigments on the first few segments. Two pairs of black eyes, prostomium heavily pigmented and antennae about the length of palps. Four pairs of tentacular cirri. Only soft papillae are present on the oral and maxillary ring. Dental formula: Up to three or four nipple like papillae on each side of Area VII, A ring of smaller conical papillae encircling the distal margin of the maxillary ring, including Area IV. Biramous parapodia with pinnate branchiae arising from the dorsal cirrus of the middle segments. The branchial filaments of the pinnate gills are simple, which begin around chaetiger 10 and bright red in alive material. At chaetiger five, the dorsal cirrus is slender and slightly lengthier than the prechaetal notoligule. Three notopodial lobes are present in the anterior feet of which the chaetigers notoligule is shortest. The ventral ramus of the anterior chaetigers comprise five neuropodial ligules that are conical and papiliform, of which the top and bottom most is pronounced. In the middle feet, the dorsal cirri develop pinnate branchiae with simple filaments. The arrangement of the notopodium remains similar to the anterior chaetigers but there is a reduction in the number of neuropodial lobes to four. In the posterior parapodia, the foot is bi-lobed, the neuropodial ramus presents a single large lobe, with the ventral cirrus much shorter and set farther back than the dorsal cirrus. Notopodial and neuropodial chaetae are similar with only long homogomph spingers present.




On clay and mud banks of estuaries and brackish waters.
