MATERIAL EXAMINED. — Japan. Ise Bay, NSMT-Pol 20508.

DISTRIBUTION. — Indopacific: southern Sakhalin ( Annenkova 1937; Uschakov 1965), Japan ( Marenzeller 1879; Moore 1903; Izuka 1912; Imajima & Hartman 1964; Imajima & Higuchi 1975), Yellow Sea ( Treadwell 1936; Uschakov & Wu 1962, 1979), Viet-Nam ( Fauvel 1939; Gallardo 1968), Singapore, India ( Fauvel 1932, 1953), Persian Gulf (Wesenberg- Lund 1949), Red Sea ( Crossland 1924).

DESCRIPTION

The specimen examined is posteriorly incomplete, with 196 setigers and c. 200 mm long; maximum width without parapodia is 8 mm. Three antennae, easily detached, deeply hidden in the nuchal fold. Simple multidentate hooded hooks begining on setigers 47-50. Ventral limbate setae present through setiger 58; dorsal limbate setae displaced to a subdorsal position at about setiger 105. Notopodia button-like, with notoaciculae. In median and posterior segments a tiny nephridial papilla is present in ventral position ( Fig. 2A ), and in dorsal position a small branchial lobe is visible. Maxillary carriers about three quarters the length of maxillae I; maxillae I with well-developed bridles; maxillae II with four teeth each, shorter than maxillae I and connected to them by wide connecting plates; maxillae III bidentate; maxillae IV unidentate; maxillae V rounded, relatively small ( Fig. 2B ).

REMARKS

The type material was not available for study, but the specimen described was collected close to the type locality, and the characters of the specimen agree with the original description. Reviewing all the records of K. heteropoda n. comb. is beyond the scope of this study; at least some of them could be different species within the purported geographic range of K. heteropoda n. comb.

DISTRIBUTION. — Western Indian Ocean and Red Sea: Djibouti, Madagascar, South Africa (Natal), and Mozambique.

DESCRIPTION

Complete syntype ( MNHN 5023) with 219 setigers, 72 mm long and 1.6 mm wide without parapodia. Prostomium conical, the antennae

A B C D

are detached, but there are scars under the nuchal fold (antennae could be lost while specimens were handled and dorsally dissected by Fauvel). Parapodia well developed, largest in posterior setigers; all notopodia button-like with notoaciculae. Simple multidentate hooded hooks start on setiger 30 ( Fig. 2C ). Nephridial papillae unilobed, beginning on setiger 134, absent from the last few setigers ( Fig. 2D ). In middle and posterior segments a small branchia is present on anterior, dorsal surface of each segment. Pygidium with four anal cirri of similar length. Maxillary carriers slightly shorter than maxillae I; maxillae I with bridles well developed; maxillae II with four to five teeth, shorter than maxillae I (less than half) and connected to them by well-developed connecting plates; maxillae III bidentate; maxillae IV unidentate; maxillae V free, relatively small ( Fig. 2E ).
