Protodiopatra willemoesii
comb. nov.
(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
