(SIO RAS, Pelamida 1961 St. 73): A, anterior end, dorsal view; B, anterior end, ventral view; C, maxillae; D, mandibles (cutting plates missing); E, parapodium of chaetiger 2, anterior view; F, parapodium of chaetiger 4, anterior view; G, parapodium of chaetiger 14, anterior view; H, parapodium of chaetiger 16, anterior view. Diagnosis: Median antenna thicker and longer than lateral ones; first four pairs of parapodia modified with subulate ventral cirri and pseudocompound bidentate falcigers with moderately long pointed hoods; postchaetal lobes present on all chaetigers; subacicular hooks starting from chaetigers 15–21; branchiae pectinate, starting from chaetigers 11–18 and continuing to the end of the body; peristomial cirri present; tube with long thin spines attached to distal slightly curved end. Description: All specimens lacking posterior ends; one posterior end with pygidium present in the material examined. Holotype 1.9 mm wide and about 50 mm long in two fragments: anterior part consisting of 21 chaetigers and posterior part consisting of 52 chaetigers. Prostomium and first few chaetigers of holotype have been dissected, and some parts are missing. Non-type specimens ranging from 1.3 to 6.5 mm in width (mean value 2.4 mm ). The most complete specimen consisting of 286 chaetigers, and about
