Diagnosis. Ceratonereis species having irregular transverse brown stripes on antero-dorsal body in live specimens (pigmentation faded slightly in preserved specimens; Fig. 1 B); Area III with more paragnaths (17–18) than Area IV; small triangular neuropodial postchaetal lobe in anterior parapodia, and dorsal notopodial ligule about ½ thickness and slightly shorter than ventral neuropodial ligule.
