MATERIAL EXAMINED.—NORTH ATLANTIC OCEAN: West Africa: Ivory Coast, 05°12′N, 04°02′W, 69 m, Reine Pokou sta SD59, 21 Nov 1969, A. Intes, collector, holotype (MNHN).

DESCRIPTION.—Holotype with 36 segments, last one minute, 12.5 mm long, and 3 mm wide including setae. Body subrectangular, flattened dorsoventrally, without color dorsally; ventral half of body with segmental brown spots lateral to midventral groove and brownish areas on ventral bases of parapodia on posterior fourth of body and pygidium. Elytra 15 pairs, on usual segments, large, oval, covering dorsum, delicate, with small group of microtubercles on anterolateral part, and some scattered micropapillae on border and surface; brownish pigmentation in form of spots over places of attachment to elytrophores and crescent-shape area on medial and posterior sides, forming almost complete circle on some posterior elytra (Figure 50C,D).

Bilobed prostomium with anterior lobes subtriangular, without peaks; anterior pair of eyes anteroventral, larger than posterodorsal pair; ceratophore of median antenna oval, in anterior notch of prostomium, style longer than prostomium; ceratophores of lateral antennae inserted ventrally, with short tapered styles; palps stout, long, tapered; tentaculophores lateral to prostomium, each with aciculum, 2 setae on inner side, and pair of dorsal and ventral tentacular cirri, similar to median antenna; styles of antennae and tentacular cirri with small papillae; brownish pigmentation on prostomium, ceratophores of antennae, tentaculophores, and area between palps (Figure 50A,B,F). Segment 2 with first pair of large elytrophores, biramous parapodia and long ventral buccal cirri similar to tentacular cirri, and lateral to ventral mouth (Figure 50A,B,G); notosetae similar to those of following parapodia; neurosetae more slender than those following, ending in slender sharp tips, upper ones with longer spinose regions (Figure 50H).

Biramous parapodia with notopodium much shorter than neuropodium, conical, with projecting acicular lobe on lower side; larger neuropodium with subconical presetal acicular lobe with digitiform supraacicular process; postsetal lobe shorter, rounded (Figure 50G,I,J). Notosetae numerous, subequal in width to neurosetae, with numerous spinose rows, of 3 lengths: shorter and longer upper ones ending in blunt tips; longest lower ones tapering distally to long capillary tips (Figure 50K). Upper neurosetae with longer spinose regions and bifid hooked tips; middle and lower ones with shorter spinose regions and bifid tips, few lower ones with entire tips (Figure 50L). Dorsal cirri with cylindrical cirrophores and styles extending to tips of neurosetae or beyond, with scattered minute papillae; dorsal tubercles indistinct; ventral cirri short, tapered, with minute papillae (Figure 50J). Pygidium small lobe with anus medial to posterior small parapodia, with pair of small anal cirri.

ETYMOLOGY.—The species is named for André Intes, the collector of the holotype.

DISTRIBUTION.—North Atlantic Ocean, West Africa, in 69 meters.
