03C69578FFCDFFBAFDFDFCCFFBA70132.taxon	etymology	Etymology The epithet oculicirrata from the Latin ‘ oculi ’, meaning ‘ eyes’, and ‘ cirrata ’, meaning ‘ in cirrus’ refers to the conspicuously pigmented eyespots laterally on the long pygidial cirri.	en	Parapar, Julio, Moreira, Juan, Barnich, Ruth (2019): A new species of Ampharete (Annelida: Ampharetidae) from the West Shetland shelf (NE Atlantic Ocean), with two updated keys to the species of the genus in North Atlantic waters.

03C69578FFCDFFBAFDFDFCCFFBA70132.taxon	description	Description of holotype (SEM images from paratypes MNCN 16.01 / 18482) MEASUREMENTS. Complete specimen of 7.5 mm length and 0.5 mm width in thorax. PROSTOMIUM. Trilobed; rather narrow and protruding median lobe delimited by deep lateral grooves; a pair of nuchal organs as circular ciliated spots located at the base of the median prostomial lobe; prostomial glandular ridges absent (Figs 1 C, 2 A, 4 A – B). EYES. Two small black, circular eyespots located posteriorly on median prostomial lobe next to the lateral grooves (Fig. 1 A, C). PERISTOMIUM. Forming a well-developed buccal lip (Figs 1 B, 5 B, 7 A). BUCCAL TENTACLES. Without groove, with two ventrolateral rows of long and slender pinnae (longer than tentacle diameter); tips of pinnae covered by cilia (Fig. 7 B). BRANCHIAE. Four pairs located in fused segments II + III and arranged in two groups with a short median gap, about one branchia wide (Figs 1 A, C, 4 B); branchiophores fused at base (Figs 1 C, 2 A – B); branchiae of same width throughout, but slightly tapering at distal end, about 3 times as long as the prostomium and 3 ⁄ 5 as long as the thorax (Figs 1 A, 4 A – B), reaching about TC 6 and provided with parallel ciliated rings from base to distal end (Fig. 4 B). Anterior three pairs of branchiae arranged in transverse row, fourth pair posterior to anterior row, between second outermost and innermost branchiae (Fig. 1 A, C). Fused segments II + III (SG 2 + 3) provided with 5 – 6 long, thin and slender chaetae (paleae), slightly longer than following regular notochaetae (Figs 1 A – C, 2 A – B, 4 A – B). THORAX. Longer and wider than abdomen (Fig. 1 A). Fourteen thoracic segments with notopodia and capillary chaetae (SG 4 to SG 17); last 12 segments also with neuropodial tori bearing single row of uncini. Nephridial papillae not observed. Thoracic notopodia as simple lobes from SG 4 and up to three times longer than wide; first notopodium somewhat reduced (Figs 1 A – C, 2 A – B). Notochaetae as simple spinulose capillaries, tapering to slender tips; arranged in two rows, capillaries from anterior row much thinner and shorter than those of posterior row (Fig. 2 C). Thoracic neuropodia from SG 6; anterior ones usually oval-shaped, about three times higher than wide (Figs 1 B, 2 A, D); gradually decreasing in size, becoming more rounded in posterior part of thorax (Fig. 3 B). Cirri and papillae in thoracic parapodia absent. Thoracic uncini with about ten teeth in two vertical rows above rostrum (Fig. 2 D). Well-developed ventral shields present to TU 10, weakly developed in TU 11 and absent in TU 12 (Fig. 5 A). Elevated or modified notopodia absent. ABDOMEN. Shorter and thinner than thorax. Eleven uncinigers, anterior two (AU 1 – 2) with neuropodia of thoracic type (‘ intermediate uncinigers’) (Figs 1 A, 3 C – D, 5 A); remaining nine abdominal uncinigers (AU 3 – 11) with enlarged neuropodial ‘ pinnules’, without dorsal neuropodial cirrus (Figs 1 A, 3 E, F, 5 A, 7 C – D). Glandular pads above pinnules not observed in intermediate or abdominal uncinigers. Abdominal uncini of AU 1 – 2 similar to thoracic ones (Fig. 3 B – D); following ones of typical abdominal shape, with about eight teeth in two vertical rows above rostrum (Fig. 6). PYGIDIUM. Crenulated due to the presence of low pygidial papillae; with a pair of long lateral cirri (Figs 1 D, F, 3 F, 7 D), each with a pygidial eye located in the proximal third of the cirrus; eyes consisting of two dark pigmented spots (Fig. 1 D, F). Fixed specimens creamy white in colour. STAINING. Head (prostomial tip especially) and ventral thoracic shields dyed by methyl blue. TUBE. Unknown. Variations Complete specimens measure 4.0 – 10.0 mm in length and 0.5 – 1.0 mm in width, although most complete specimens are about 4.0 – 5.0 mm long. One specimen (MNCN 16.01 / 18482) observed with the ventral pharyngeal organ protruded (Fig. 7 A). The buccal lip may appear smooth or rough depending on the state of contraction of the buccal opening (Figs 5 B vs 7 A). The gap between groups of branchiae is difficult to see in many specimens, but it is obvious in the holotype (Fig. 1 C) and several paratypes. Some paratypes have pygidial eyes consisting only of a single pigmented spot (Fig. 1 F). Two females (MNCN 16.01 / 18475, 7 mm long and MNCN 16.01 / 18481, 10 mm long) bear oocytes in the coelomic cavity.	en	Parapar, Julio, Moreira, Juan, Barnich, Ruth (2019): A new species of Ampharete (Annelida: Ampharetidae) from the West Shetland shelf (NE Atlantic Ocean), with two updated keys to the species of the genus in North Atlantic waters.
