Prostomium broadly rounded, posterior end short, extending to chaetiger 1, barely tapered. Nuchal organs with short median and long lateral ciliary bands, median bands extending to tcb of chaetiger 2 and recurved lateral bands up to chaetiger 3; metameric dorsal ciliated organs double-paired, usually present from chaetiger 3. Branchiae from chaetiger 1, continuous to almost end of body, length of first pair of branchiae about two thirds length of second pair; branchiae mostly free from notopodial lamellae. Ventral epidermal glands present from about chaetiger 3 to posterior middle body chaetigers; two pairs of glands per chaetiger. Postchaetal lamellae rounded, notopodial prechaetal lamellae present in anterior and middle chaetigers. From chaetiger 11 row of 4–5 tridentate hooded hooks replacing posterior row of capillaries in neuropodia, uppermost tooth very inconspicuous. Pygidium with two pairs of anal cirri, dorsal pair thinner and shorter.
