Emended by Blake 2017.</p><p>Type species. Berkeleyia profunda Hartman, 1971, Mozambique Basin, 4886–5069 m .</p><p>Diagnosis. (after Blake 2020) Prostomium pointed, conical; peristomium with one or two asetigerous rings. Branchiae from posterior thoracic or abdominal segments. Thoracic noto- and neuropodia with one postsetal lobe, sometimes absent or inconspicuous on anteriormost setigers; subpodial lobes absent; abdominal setigers with simple noto- and neuropodia; neuropodia with or without ventral cirrus; interramal cirri absent. Thoracic noto- and neurosetae all capillaries. Abdominal notosetae include capillaries; pointed spines present or absent; furcate setae present or absent; neuropodia with capillaries and protruding acicular spines, or only spines.</p><p>Remarks. The genus Berkeleyia is similar to Leitoscoloplos Day, 1977 in lacking spines or uncini in thoracic neuropodia. Species of Berkeleyia differ in having neuropodial spines in abdominal setigers and abdominal notopodial spines present or absent. Until recently, Berkeleyia was known for a single deep-water species, B. profunda Hartman, 1971, from the Indian Ocean. Blake (2017) subsequently described four additional species from off South America and Antarctica, three of which were from deep water, with B. hadala Blake, 2017 from the Peru-Chile trench in 6143 m representing the deepest known occurrence for an orbiniid polychaete. Another deep-water species, B. lelievrei Blake, 2020, was recently described from hydrothermal vents on the Juan de Fuca Ridge. Another deep-water species from the Condor Seamount off the Azores is described herein as new to science and is the first species of the genus to be reported in the North Atlantic Ocean. A comparison of the now seven known species of Berkeleyia is presented in Table 1.</p></div>	https://treatment.plazi.org/id/D90A87FCFFA71D4AFF3E1CECFD66724C	Public Domain	No known copyright restrictions apply.

A moderately sized species, all specimens incomplete. Body generally cylindrical in cross section throughout; setigers 1–4 longest, then all segments consistently short to end of body. Holotype (MCZ IZ 0172989) with 28 setigers, posterior setigers coiled, 7.1 mm long as stretched out, 0.5 mm wide across setiger 6; largest paratype (MCZ IZ 172990) with 25 setigers, 7.4 mm long, 0.8 mm wide. Posterior end missing on all specimens. Color in alcohol: light tan without pigment.</p><p>Pre-setiger region triangular, about as long as first two setigers (Fig. 1A–B, 2A). Prostomium narrow, tapering anteriorly to pointed tip, posteriorly merging indistinctly with peristomium; eyes absent; nuchal organs not observed. Peristomium a single smooth ring dorsally (Fig. 1A, 2A); ventrally with mouth bordered by a pair of anterior lips and a curved crenulated posterior lip (F ig. 1B); largest paratype with oblong proboscis everted (Fig. 2B).</p><p>Thoracic segments include first 11–12 setigers, with short cirriform notopodial postsetal lobes from setiger 5 (Fig. 1A), these gradually increasing in length over subsequent setigers becoming elongate and fingerlike in anterior abdominal setigers(Fig. 1A) and continuing throughout;neuropodia similar to notopodia with short cirriform postsetal lobe from setiger 6 (Fig. 1B); most thoracic setigers with lateral parapodia, shifting dorsally by about setigers 9–10 (Fig. 1A). Abdominal parapodia shifted dorsally and identified by appearance of prolonged neuropodium bearing short ventral cirrus (Figs 1A, C, 2C); notopodia rounded lobes bearing elongate postsetal lobe (Figs 1A, 2C); subpodial lobes absent. Branchiae from setigers 11–12 or transition from thoracic to abdominal setigers, continuing to near posterior end; branchiae short, rounded apically (Figs 1A, 2C). Anterior dorsal segmental border of branchialbearing setigers with a pair of minute papillate dorsal organs (Fig. 1A [arrows], 2C–D [arrows]).</p><p>Setae include crenulated capillaries, furcate setae, and narrow neuropodial acicular spines (Fig. 1C–G). Thoracic noto- and neuropodial setae with long, crenulated capillaries with up to 25 setae in dense bundle, reduced in number over last 2–3 thoracic setigers; furcate setae first appearing among capillaries of setigers 12–13 or last thoracic setigers in both noto- and neuropodia. Abdominal notopodia with 2–3 crenulated capillaries and 1–2 furcate setae; abdominal neuropodia with furcate setae, a few crenulated capillaries and 1–2 narrow acicular spines. Furcate seta with long shafts and two short blunt-tipped tynes, each tyne with fine needles forming a web between tynes (Fig. 1C, G). Spines only weakly curved, with narrow blunt tip (Fig 1C–F).</p><p>Pygidium unknown.</p><p>Remarks. Berkeleyia condoriensis sp. nov. is the seventh species of the genus to be described (Table 1). The new species is most similar to B. abyssala Blake, 2017 and B. weddellia Blake, 2017, both from deep-water in Antarctic seas, in having a triangular-shaped pre-setiger region consisting of a short pointed prostomium merged almost indistinctly with the peristomium. Berkeleyia abyssala has the change from thorax to abdomen at setigers 10–11, branchiae from setigers 9–10, and furcate setae from setigers 9–10; in B. weddellia the thorax/abdominal change is at setiger 8, branchiae start on setiger 18 and furcate setae on setiger 9. In contrast, in B. condoriensis sp. nov. the thorax/abdominal change is at setigers 11–12, branchiae start on setigers 11–12 and furcate setae on setigers 12–13. The minute paired papillate dorsal organs on the anterior segmental border anterior to the branchiae in B. condoriensis sp. nov. have not been observed on other species of the genus.</p><p>Biology. Apart from Berkeleyia heroae Blake, 2017 from intertidal and shallow subtidal depths off Argentina, the other six species are all from deep water of 1000 m or greater. The new species, B. condoriensis sp. nov., is the first species of the genus to be reported from the North Atlantic Ocean and from a seamount.</p><p>Etymology.

Microrbinia linea Hartman, 1965, by monotypy.</p><p>Diagnosis. (Emended) Body long, threadlike; thoracic region with a few short uniannulate segments gradually transitioning to elongate (biannulate) abdominal segments. Prostomium conical, tapering anteriorly; with paired nuchal organs; eyespots absent. Peristomium with one or two asetigerous rings. Noto- and neuropodia with welldeveloped postsetal lobes; branchiae absent; parapodia lateral to dorsolateral, some notopodia directed dorsally, but not shifted onto dorsal surface in abdominal segments. Branchiae absent. Setae include crenulated capillaries throughout; posterior notosetae include acicular spines; neuropodia with acicular spines present or absent; furcate and flail setae absent. Pygidium with 2–4 anal cirri. Males with a conical gland-like dorsal organ on a few abdominal segments.</p><p>Remarks.: The genus Microrbinia is currently known only from the type-species, M. linea from the U.S. Atlantic continental slope (600–3015 m) (Hartman 1965; Blake 1993, 1994, 2021). The species is unusual among orbiniids in having a conical gland-like structure on the dorsal surface of some anterior abdominal segments (Blake 1993; 2021). These structures appear to be associated with males; females have one or two elongate swollen segments containing large eggs, but none of the gland-like dorsal organs. Microrbinia linea has unusual serrated notopodial acicular spines in middle and posterior abdominal segments that have not been reported in other orbiniids. Another species has been found among the orbiniids collected from the Condor seamount and has several characters that required the definition of the genus to be emended. The new species has two peristomial rings instead of one, two anal cirri instead of four, and the acicular spines occur in both noto- and neuropodia instead of only notopodia and are smooth instead of serrated.</p></div>	https://treatment.plazi.org/id/D90A87FCFFA11D4CFF3E1AE5FE07701C	Public Domain	No known copyright restrictions apply.

A small threadlike species; holotype (MCZ IZ 172991) complete with 38 setigers, 4.2 mm long, 0.2 mm wide across setiger 16; incomplete paratype (MCZ IZ 172992) larger, with 27 setigers, 5.0 mm long, 0.35 mm wide across setiger 4. Body cylindrical, with 5–7 short thoracic setigers with uniannulate interramal rings, followed by larger, thicker, abdominal setigers with biannulate interramal rings along most of body (Figs 3A–B, 4A); a few transitional setigers with either uni- or biannulate interramal rings variously developed; thoracic setigers with parapodia lateral, shifting a little dorsally along abdominal setigers, but never completely dorsally elevated. Dorsal and ventral groove and ridges absent apart from a large flattened narrow plate on ventral surface of thoracic setigers (Fig. 3B). Specimens believed males with a large conical gland-like dorsal organ on individual segments (Fig. 4B–C); these with distinct apical pore present (Fig. 4C). No specimens observed with oocytes or ova. Color in alcohol light tan.</p><p>Pre-setiger region long, narrow, about as long as first 2.5 to 3 setigers, merging with setiger 1 both dorsally and ventrally (Figs 3A–B, 4A). Prostomium conical, tapering to narrow rounded tip (Fig. 4A); nuchal organs not observed; eyespots absent. Peristomium with two rings, first smaller, merged anteriorly with short prostomium (Fig. 4A); second larger, encompassing mouth ventrally with about ten short lobes (Fig. 3B); proboscis not observed.</p><p>Thoracic setigers numbering 5–7, each relatively short, about 2–3 times wider than long and with a single narrow transverse intersegmental ridge or ring both dorsally and ventrally (Fig. 3A–B). Transition to abdominal segments denoted by a narrowing and elongation of individual segments and with change from a single intersegmental ring to two rings (Figs 3A, 4A). Abdominal parapodia and setae arising from middle of each segment. Branchiae entirely absent.</p><p>Notopodia short, conical, with a distinct postsetal lobe on all setigers; this becoming longer and fingerlike along most of body (Fig. 3A, D); neuropodia short, weakly curved, with a short digitate postsetal lobe first present in posterior thoracic setigers continuing posteriorly, not as long as in notopodia (Fig. 3B, D).</p><p>Setae include camerated capillaries and noto- and neuropodial acicular spines (Fig. 3E–F). Noto- and neuropodia with a spreading fascicle of 6–10 camerated capillaries in thoracic setigers and anterior abdominal setigers; gradually reduced to 2–5 capillaries in abdominal setigers. Notopodia with 1–2 curved acicular spines with hooked tips from setigers 12–14, continuing posteriorly; neuropodia with 1–2 pointed acicular spines from setigers 8–9.</p><p>Pygidium divided into two lobes; with two anal cirri, one arising on each lobe (Fig. 3C).</p><p>Remarks. Microrbinia hartmanae sp. nov. is the second species of the genus to be described. The first, M. linea, was described by Hartman (1965) from off New England in deep water. Blake (2021) provided a detailed description of the species based on extensive collections off the U.S. Atlantic coast in 600–3015 m. Blake (1993, 2021) reported that some specimens of M. linea had unusual a conical gland-like dorsal organ on some abdominal segments. These were suggested to be on males because other specimens with eggs were obviously females and lacked these structures. In the present study, similar dorsal organs were observed on a few specimens of M. hartmanae sp. nov. However, no evidence of eggs or oocytes were found either on these specimens or those that lacked the dorsal organs.</p><p>Morphologically, M. hartmanae sp. nov. differs from M. linea in having a small conical-shaped prostomium, two peristomial rings, abdominal segments that are about as wide as long and with parapodia arising from midbody, blunt-tipped and apically curved acicular spines in the notopodia and straight, more pointed spines in the neuropodia, and a pygidium with two anal cirri. In contrast, M. linea has a larger, triangular-shaped prostomium, one peristomial ring, abdominal segments that are narrow and as much as three times longer than wide and with parapodia arising from near the posterior end of each segment. In addition, the notopodial acicular spines of M. linea are serrated along one edge before curving to a pointed tip instead of smooth shafts, neuropodial spines are absent instead of present, and the pygidium has four anal cirri instead of two.</p><p>Biology. Microrbinia hartmanae sp. nov. is known only from the summit of the Condor Seamount in 206 m. In contrast, M. linea is a deep-water species that occurs off the U.S Atlantic coast from 600 to 3015 m and off the Amazon River in 770–1500 m (Hartman 1965; Blake 2021). The unusual dorsal glandular organs found in both species have not been reported for other orbiniids. It is likely that these are a copulatory organ because specimens of M. linea with eggs did not have these organs (Blake 1993, 2021).</p><p>According to Bongiorni et al. (2013), a total of 1711 specimens of benthic invertebrates were identified from three replicate box cores collected at Station 9 on the summit where Microrbinia hartmanae sp. nov. was collected. From these specimens, 81 species were identified, of which 45 species were polychaetes. The onuphid polychaete, Mooreonuphis pallidula (Hartman, 1965), the syllid polychaete, Pionosyllis weismanni (Langerhans, 1879), and an amphipod, Lembos sp., collectively comprised 76% of the total macrofaunal abundance at the site.</p><p>Microrbinia hartmanae sp. nov. is likely a subsurface deposit feeder, but owing to its small size and narrow body, probably occurs within 5 cm of the surface. Its only congener, M. linea, was found to have 96.5% of its total abundance in the upper 5 cm of sediment cores, with the majority in the 2–5 cm depth interval (Blake 1994).</p><p>Etymology. This species is named for the late Dr. Olga Hartman, prominent annelid systematist who originally described the genus Microrbinia .</p><p>Distribution.
