Elytra 12 pairs, becoming more elongate posteriorly (Figures 30e-h; 31f-k); first pair subtriangular, each with

12-13 papillae on anterior and lateral borders; rest of elytra subreniform to subrectangular, lateral borders with single notch or up to 8 digitiform or wide processes between anterior and posterior rounded lobes, some biarticulate. Branchiae 12 (holotype and paratype from Togo) or 13 (paratype from Adriatic) pairs, inflated, with distal branchial cirrus (Figure 31a). Dorsal cirri, on segments 3 and 6, subulate. Posterior lamellae, beginning on segment 28 or 29, subcordiform to subconical (Figure 31b).

Prostomium covered by segment II and attached middorsally on posterior half; median antenna short, conical, inserted anterodorsally on prostomium; lateral antennae conical, inserted more ventrally; palps elongate-tapered, extending beyond tentacular cirri; 2 pairs small eyes on lateral border; nuchal organs oval, lateral to prostomium (Figure 30a). Tentacular parapodia (I) narrower basally, enlarged distally, each with dorsal and ventral tentacular cirri, subequal in length or ventral slightly longer, 2 acicula and 2 bundles of smooth

and spinous capillary setae (Figure 30b). Ventral buccal cirri on segment II thicker and longer than those following (Figure 30c).

Biramous parapodia supported by light amber-colored acicula and neuropodial hammer-shaped distal plates (Figure 31a). Notopodial acicula with hooked tips. Notopodial capillary setae smooth and spinous, forming long, spreading bundles on posterior parts of notopodia; stout light amber-colored notopodial hooks, beginning on segment III, smooth, with tips tapered to fine tips or flattened spatulate. Neuropodial acicula with hammer-shaped distal plates. Neurosetae of several kinds: 1-2 upper pectinate setae (Figure 31c); limbate capillary neurosetae with long tapering tips (Figure 30d); lower more slender nonlimbate neurosetae; without acicular neurosetae in anterior segments. Upper neurosetae of posterior region stouter than lower ones, curved downward, tapering to fine tips, faintly spinous along bend (Figure 31b,d,e). Ventral cirri of anterior few segments subulate, tapered; following ventral cirri globular, with short clavate tips (Figure 31a,b). Pygidium with single long anal cirrus on right side; cirrus finely papillate along one side; left cirrus short, rudimentary. Pharynx not extended.

DISTRIBUTION.—West Africa, Central-east Atlantic (French Congo, Togo), Adriatic. In 34 meters.

Grubeulepis augeneri Pettibone, 1969

Grubeulepis augeneri Pettibone, 1969:38, figs. 30, 31 [synonymy].—Uebelacker, 1984:24–11, figs. 24–7, 8a-i.

MATERIAL EXAMINED.—Gulf of Mexico: MAFLA sta 2208B, E, Jul 1976, 27°56′N, 83°27′W, 30 m, clayey sandy silt, adult and juvenile (USNM 98355); sta 2209, Jul 1976, 27°52′N, 83°33′W, 34 m, clayey sandy silt, adult (USNM 98356); sta 2959, Aug, Nov 1977, 25°40′N, 83°05′W, 60 m, silty fine sand, juvenile and advanced juvenile (USNM 98357). SOFLA sta 16B, D, Nov 1980, Jul 1981, 25°45′N, 83° 11′W, 54 m, fine sand, 2 adults, 2 advanced juveniles (USNM 74464-5); sta 18D, Apr 1981, 25°45′N, 83°42′W, 87 m, medium sand, advanced juvenile (USNM 74466); sta 28C, Aug 1981, 24°47′N, 83°13′W, 58 m, fine sand, adult and advanced juvenile (USNM 74467).

DESCRIPTION OF ADULT SPECIMENS FROM GULF OF MEXICO.—Length of 4 adult specimens 14–18 mm, width 3–4 mm, segments 35–36. Elytra 12 pairs, increasing in length posteriorly (Figure 20A–E); 1st elytra with papillae on anterior border (Figure 20A); following few elytra with 1–3 lateral processes, some with terminal buds (Figure 20B,C); posterior elytra with up to 6 wide lateral processes, without terminal buds (Figure 20D,E).

Elytrigerous parapodium of segment 2 with capillary notosetae; neuropodium with upper pectinate seta, limbate capillary and lower non-limbate capillary setae, and long buccal cirrus (Figure 20F). Cirrigerous parapodium of segment 3 with stout notopodial hooks in addition to posterior bundle of capillary setae; bilimbate capillary neurosetae with long tapering tips, middle ones somewhat stouter, without acicular neuroseta (Figure 20G–I).

Notopodia of middle biramous parapodia with posterior bundle of long capillary notosetae and long, stout, smooth notopodial hooks, with tips tapered, truncate, or flattened, spatulate; neuropodia with fan-shaped bundle of neurosetae: upper one pectinate, limbate capillaries with middle ones slightly stouter, and lower group of short capillaries (Figure 21A–D). Posterior lamelligerous parapodia differing in having upper group of neurosetae stouter than lower group, bent downward, and finely spinous along bend, with curled slender tips (Figure 21E–G).

DESCRIPTION OF JUVENILES FROM GULF OF MEXICO.—Length of five advanced juveniles 8.5–12 mm, width 2–3 mm, segments 31–34. Elytra 12 pairs, increasing in length posteriorly but not as much in comparison to adults (Figure 22A,D); 1st elytra with papillae on anterior border (Figure 22A); following few elytra with 1–3 lateral processes, some with terminal buds (Figure 22B); posterior elytra with up to 5 wide lateral processes, without terminal buds (Figure 22C,D), thus differing from adults only in size. Cirrigerous parapodia of segment 3 differing from adults by presence of stout acicular neuroseta in middle of bundle (Figure 22F,G). Middle elytrigerous and branchial parapodia similar to adults (Figure 22H–J). Posterior lamelligerous parapodia similar to adults, with upper neurosetae stouter than lower ones, bent downward and spinous along bend, with curled slender tips (Figure 22K,L). Small juvenile (USNM 98357) 5 mm long, 2 mm wide, with about 26 segments (posterior end damaged). Acicular neuroseta present in parapodia of segments 3, 4, and 5.

DISTRIBUTION.—West Africa, Adriatic, in 34 meters; Gulf of Mexico, in 19–87 meters.
