Diagnosis. Prostomium with broadly rounded, distinctly projecting forward over peristomium; posterior prostomial margin not discernable as completely fused with dorsum (Figures 2 A–B, 3 A–C); occipital antenna absent. Nuchal organ as U-shaped ciliary band lateral to the fused prostomium and dorsum extending to the beginning of the second chaetiger (Figure 3 A–B). Metameric dorsal ciliated organs absent. Interparapodial lateral pouches absent. Dorsal branchiae from chaetiger 2 to maximally chaetiger 17 (Figures 2 A, 3 A–D, 5 left). Notopodial postchaetal lamellae on chaetiger 2 enlarged in medium- and large-sized specimens (Figure 3 B). Hooded hooks with pair of small, somewhat perpendicular apical teeth above main fang present in noto- and neuropodia (Figures 2 C, I, H, 3 F, 5 right). Rows of holes present on the dorsum of chaetigers of the branchiate region or adjacent to it (only observable with SEM, Figure 4). Pygidium with 4 cirri of about equal length (Figures 2 C, 3 G). Description. Widest specimen 0.57 mm wide (at chaetiger 10), 17.5 mm long for 71 chaetigers. Prostomium with broadly rounded, slightly inflated anterior rim, distinctly projecting forward over peristomium, laterally separated from peristomium by furrow, posterior margin not discernable as completely fused with dorsum (Figures 2 A–B, 3 A–C). Occipital antenna absent. Prostomium with two pairs of small red eyes arranged in trapezoid: anterior pair farther apart with eyes located just behind the inflated anterior rim, posterior pair close to the anterior pair, eyes close to the lateral prostomial margins; usually lost in formalin-fixed specimens but visible in ethanolfixed material. Peristomium separated from the prostomium, not well developed. Palps arising in front of the nuchal organs, reaching back to chaetiger 10 (Figure 3 B, palps lost in this picture but scar at former point of attachment discernable). Nuchal organ as U-shaped ciliary band lateral to the fused prostomium and dorsum reaching the beginning of chaetiger 2 (Figure 3 A–B). Metameric dorsal ciliated organs absent. Dorsal branchiae present from chaetigers 2 to maximally chaetiger 17, last branchiate chaetiger dependent on specimen size, branchiae usually present to chaetiger 6 in small specimens, in very small specimens very few branchiae present (Figures 2 A, 3 A–D, 5 left); branchiae easily lost. Branchiae cirriform, ciliated on outer margins, separate from notopodial lamellae throughout; first and last branchiae smallest, about half as long as notopodial lobe of the respective chaetiger; branchiae in between all of about the same length, in small specimens slightly shorter than notopodial lamellae, in medium-sized and large specimens as long as notopodial lamellae of the same chaetiger or longer, but even in largest specimens hardly touching above dorsum (Figures 2 A, E, 3 A–D, 4 A–C). Parapodia on first and second chaetiger slightly more dorsally positioned than parapodia in following chaetigers (Figure 3 A). Both notopodial and neuropodial lamellae relatively small. On first chaetiger notopodial lamellae very small, short cirriform; neuropodial lamellae subtriangular with broad base, longer than notopodial lamellae (Figure 2 D). Second chaetiger with fully developed notopodial lamellae, often longest notopodial lamella of all, longer than branchiae of the respective chaetiger, leaf-like and prominent particularly in larger specimens (Figures 3 B, 4 A–B); neuropodial lamellae subtriangular to cirriform, shorter than notopodial lamellae (Figure 3 C). From third chaetiger notopodial and neuropodial lamellae in branchiate chaetigers tapered to cirriform with notopodial lamellae sometimes slightly longer than neuropodial lamellae or both of equal length (Figure 2 E). Postbranchiate region with shorter lamellae with broader base in both rami, further decreasing in size towards the end of the body though in about 5–8 posteriormost chaetigers again slightly longer and cirriform (Figures 2 G–H, 3 G). Praechaetal lamellae not developed but large specimens with little bulge stainable with methyl green in front of notopodial chaetae in some chaetigers of the branchiate region. Interparapodial lateral pouches absent. Dorsal crests absent. Two rows of holes present on the dorsum of some chaetigers of the branchiate region or adjacent to it (only observable with SEM, Figure 4): starting on chaetigers 3–5 with few large holes (N= 1–2) next to the branchial base, on succeeding chaetigers number of holes increasing to up to 10, then arranged in a straight row from the branchial base nearly all the way across the segment (Figure 4 A–C); from about chaetiger 6 second anterior group of holes present, again starting with few holes only, later with increasing number of holes (N max= 7) describing an outward curved line from the notopodial base to the anterior intersegmental border (Figure 4 A–C); both rows of large holes often accompanied by irregular anterior and posterior rows of small holes (Figure 4 D). Additional single or very few large holes sometimes present laterally between parapodia of the branchiate region (Figure 4 A). Cilia originating from inside the large holes often present (impairing the observation of this character). First postbranchial chaetiger usually with very few large and some small holes next to the branchial base; on following chaetigers holes no longer present (Figure 4 E). Chaetae in two rows, anterior and middle chaetigers with two rows of capillaries (Figure 3 C), until chaetigers 10–14 with granulations, afterwards smooth (Figure 2 J), until chaetigers 20–25 with narrow sheaths, thereafter without sheaths; anterior row of capillaries slightly shorter than posterior row. Anterior row of capillaries replaced by row of hooks (Figure 3 E) from chaetigers 15–22 in neuropodia and from chaetigers 19–37 in notopodia, first presence of hooks depending on specimen size (Figure 5 right); hooks hooded, tridentate, with pair of small, somewhat perpendicular apical teeth above main fang (Figures 2 I, 3 F); 1–7 hooks in neuropodia and 1–6 hooks in notopodia (Figure 2 H). Posteriormost chaetigers with 3–4 long simple capillaries behind rows of hooks in neuro- and notopodia (Figure 3 G). Sabre chaetae usually absent but single large specimen from Seine Seamount with sabre chaeta in three posterior chaetigers (50 th– 52 th) at the end of the fragment. Pygidium with 4 cirri of about equal length, arranged as dorsal and ventral pair; cirri with thin elongated tips (Figures 2 C, 3 G); anus terminal. Pigmentation . Pigment not discernable in preserved specimens. Methyl green staining pattern . Anterior inflated rim of the prostomium, peristomium, branchiae, and postchaetal lamellae most intensively stained. In larger specimens sometimes darker stained low praechaetal bulge in notopodia of branchiate chaetigers observable. Some specimens with metameric pairs of dark-blue dots on the ventrum from about chaetiger 8 to some mid-body chaetigers. Ecology. Aonidella cf. dayi was found on seamounts of the NE Atlantic in coral and crushed shell gravel in about 178–300 m of depth. Geographical distribution. NE Atlantic Ocean: Great Meteor Seamount, Little Meteor Seamount, Irving Seamount, Hyères Seamount, Seine Seamount. The species may also occur in the Mediterranean Sea, off the Atlantic coast of the Iberian Peninsula and in deep waters south of the Canary Islands (see Remarks). Remarks. Aonidella specimens found on the NE Atlantic seamounts are very close to Aonidella dayi Maciolek in López-Jamar, 1989. The amended description of A. dayi by Maciolek (2000) was based on the examination of specimens mainly from NW Atlantic but also on few specimens from the Mediterranean Sea and from deep waters South of the Canary Islands. Maciolek (2000) already noticed that her description reports the presence of 10–12 pairs of branchiae whereas other authors reported up to 16 pairs of branchiae, e.g Imajima (1992) for specimens from Japan and López-Jamar (1989) for specimens from the Gulf of Cadiz. In specimens from the Atlantic seamounts the number of branchiae was found to be size-dependent and largest specimens usually to have branchiae up to chaetigers 12–17 (i.e. 11–16 pairs of branchiae) (Figure 5 left). Direct comparison of specimens from both sides of the Atlantic Ocean revealed that largest specimens (> 0.5 mm wide at chaetiger 10) from off Brazil and from off the U.S. coast have fewer pairs of branchiae compared with specimens of the same size from the Eastern Atlantic seamounts (11–13 pairs versus 14–16 pairs) (Figure 5 left). Also many small seamount specimens (0.18–0.5 mm wide) with 10–15 pairs of branchiae were found. Differences concerning the start of neuropodial hooks between specimens from the Eastern and Western Atlantic were less distinct (Figure 5 right). For A. dayi from the Western Atlantic the presence of hooks with 2–4 apical teeth was reported (Maciolek 2000). In their taxonomic catalogue of the Spionidae of the Grand Caribbean Delgado-Blas & Salazar-Silva (2011) list a record of Aonidella cirrobranchiata (Day, 1961) with the note, that the presence of this species in the Grand Caribbean is doubtful because specimens of Johnson (1984) (Gulf of Mexico) and Ibarzabal (1986) (Cuba) have a slight medial indentation on the prostomium, four eyes instead of none, and hooded hooks with 2–4 teeth. It seems obvious that those records should rather be assigned to A. dayi than to A. cirrobranchiata , but again : Published as part of Bick, Andreas, Guggolz, Theresa & Götting, Miriam, 2014, Spionidae (Polychaeta: Canalipalpata: Spionida) from seamounts in the NE Atlantic, pp. 201-245 in Zootaxa 3786 (3) on pages 209-217, DOI: 10.11646/zootaxa.3786.3.1, http://zenodo.org/record/252942 : {"references": ["Lopez-Jamar, E.
