Adult morphology (Material from the type locality, Gulf of Naples, Italy) . Neotype (SMF 24359) largest complete individual 30 mm long, 1.5 mm wide with 175 chaetigers; other individuals (MIMB 28148) 8 to 11 mm long, with 60 to 100 chaetigers. Pigmentation absent on body. No pigment on palps in a 60-chaetiger individual, and in an individual 11 mm long with 100 chaetigers; 75-chaetiger individual and neotype with five and seven paired black bands on each palp, respectively. Prostomium anteriorly incised, extending posteriorly to end of chaetiger 3 as a low caruncle. Occipital antenna absent in 60- and 75-chaetiger individuals; larger individuals, including neotype, with short occipital antenna on prostomium. Eyes absent in neotype; up to four eyes present or eyes absent in other individuals. Chaetiger 1 with short capillaries only in neuropodia. Chaetiger 5 with up to four dorsal superior winged capillaries, six heavy falcate spines alternating with bilimbate-tipped companion chaetae, and six ventral winged capillaries; falcate spines with lateral flange. Hooded hooks in neuropodia from chaetiger 7, up to ten in a series, not accompanied by capillaries; hooks bidentate, with constriction on shaft. Posterior notopodia (from chaetiger 155 onwards in a 175-chaetiger neotype) each with 1–2 heavy recurved spines and a tuft of slender capillaries; spines with curved tips directed medially. Branchiae from chaetiger 7 continuing posteriorly along most of body (on chaetigers 7–154 in neotype). Pygidium white, cup-shaped with dorsal gap. Of five individuals, two were females (175-chaetiger neotype with oocytes in chaetigers 40–113), two had no gametes, and one was male (10 mm long with 75 chaetigers, with branchiae on chaetigers 7–39, and nototrochs composed of single rows of cilia) with spermatocytes, tetrads of spermatids and individual spermatozoa (introsperm with elongated head and midpiece, similar to those in other Polydora species) floating in coelom in chaetigers 29–44. Other material from Italy and France. Large worms of a size range similar to specimens from type locality (see above). Black pigment diffused on anterior part of prostomium (in front of eyes) in some individuals, varying from weak only on lateral sides to intense on lateral and dorsal sides of prostomium. Similar pigment of variable intensity diffused on dorso-lateral sides of peristomium in some individuals. Up to ten black paired bands present on each palp and black pigment diffused on pygidium in some individuals. Notopodia of 5–16 posterior chaetigers with heavy recurved spines in addition to capillaries. Pygidium flaring disc with wide dorsal gap. Material from South Korea ( Polydora hoplura in Korean galgori-kin-eolgool-gat-ji-rung-i, meaning a long face worm with hook). Up to 55 mm long and 2 mm wide for 180 chaetigers. Body pale to light tan in life; with numerous glandular cells on dorsal side from chaetigers 10–15 giving dorsum whitish appearance (Fig. 2 A). Remains of larval melanophores present on dorso-lateral sides of 15–16 anterior chaetigers in individuals up to 50– 60-chaetiger stage; larger worms usually lacking black pigment on body. Black narrow longitudinal stripes on lateral sides of anterior part of prostomium and a pair of small black patches on dorsal side of peristomium present in three individuals (of more than one thousand examined). Up to 25 black paired bands present on each palp in individuals with more than 50 chaetigers (Fig. 2 A–D); bands usually regularly arranged and of equal intensity along palp (Fig. 3 A); in some individuals bands more intense and distinct on distal half of palp. Number of bands weakly correlated with total number of chaetigers in an individual (Fig. 3 B). Prostomium with shallow anterior incision often seen only in ventral view, posteriorly extending to end of chaetiger 3 (usually to middle of chaetiger 3) as a low caruncle, shorter in small individuals (Fig. 3 C). Short occipital antenna present on caruncle in individuals with more than 90 chaetigers; smaller individuals usually without antenna. Two pairs of black eyes usually present. Palps as long as 15–30 chaetigers, with longitudinal frontal groove lined with fine cilia, latero-frontal motile compound cilia, and papillae with short non-motile cilia densely arranged in 4–5 rows along both sides of frontal groove (Fig. 2 C), and also sparsely scattered on lateral and abfrontal palp surfaces all along palp length (Fig. 2 D). Chaetiger 1 with short capillaries in neuropodia and small postchaetal lamellae in both rami; notochaetae absent. Notopodia of posterior chaetigers with two kinds of heavy spines in addition to 2–6 slender capillaries (Fig. 2 H). One spine slender and slightly curved, awl-like (Fig. 2 H, sl ), second spine heavily recurved, sickle-shaped (Fig. 2 H, he ); spines with curved tips directed medially. Slender awl-like spines first appearing in chaetiger 18 in juveniles with 18–19 chaetigers, while heavy sickle-shaped spines first appearing in notopodia in juveniles with 25–30 chaetigers (Table 1: 25-chaetiger individual). Both kinds of spines beginning from more posterior chaetigers in larger individuals (Fig. 3 D) what can only be explained by their falling out from anterior notopodia with growth of worms. Slender awl-like spines and heavy sickle-shaped spines developing and falling out at different rates and, therefore, arranged in notopodia differently (Table 1). In notopodia of new segments developing in growth zone in front of pygidium in worms with more than 25 chaetigers, capillaries and heavy sickle-shaped spines developing first while slender awl-like spines developing later. Consequently, notopodia of a few posteriormost chaetigers bearing only capillaries and heavy sickle-shaped spines. With growth, heavy sickle-shaped spines of anteriormost spine-bearing notopodia falling out first while slender awl-like spines falling out gradually afterwards. Consequently, notopodia of a few anteriormost chaetigers bearing only capillaries and slender awl-like spines. Middle spine-bearing notopodia having both kinds of spines in addition to capillaries. Anterior position of spines correlated with arrangement of branchiae (Table 1). In small individuals, spines first present from 4–17 chaetigers after last branchiate chaetiger. In mid-size individuals, slender awl-like spines usually from last branchiate chaetiger and heavy sickle-shaped spines usually beginning 1–3 chaetigers after last branchiate chaetiger. In large individuals, slender awl-like spines usually from 1–3 chaetigers before last branchiate chaetiger, while heavy sickle-shaped spines usually beginning in last branchiate chaetiger or in next chaetiger after it. Chaetiger 5 twice as large as chaetigers 4 and 6, with up to six dorsal superior winged capillaries, seven heavy falcate spines arranged in a slightly curved diagonal row and alternating with bilimbate-tipped companion chaetae, and seven ventral winged capillaries. Dorsal superior and ventral capillaries shorter and fewer than those on adjacent chaetigers. Falcate spines with large subdistal flange on lateral side; upper and inner parts of flange thinner than lower and outer parts, thus in newly developed spines (situated in posterior part of spine row) whole structure appearing as a large tooth joined to main fang by thin sheath; in older spines (situated in anterior part of spine row) lateral flange greatly worn and indistinct. Hooks in neuropodia from chaetiger 7, up to 12 in a series, not accompanied by capillaries. Hooks bidentate; shaft slightly curved, with weak constriction in upper part (Fig. 2 G). Branchiae from chaetiger 7, full-sized from chaetigers 10–12, gradually diminishing in size along posterior half of body, absent on 5–20 posteriormost chaetigers (Fig. 3 D). Branchiae flattened, with surfaces oriented parallel to body axis, free from notopodial postchaetal lamellae, with longitudinal row of cilia along inner surface. Nototrochs from chaetigers 7–8 onwards, each composed of one row of short cilia, on branchiate chaetigers extending onto branchiae. Pygidium disk-like to cup-shaped, usually with distinct dorsal gap, white due to numerous striated glandular cells (Fig. 2 F). Glandular pouches in neuropodia from chaetiger 6 in individuals with up to about 30 chaetigers, from chaetiger 7 in larger individuals; pouches large in chaetigers 7–9 and considerably smaller in successive chaetigers. Digestive tract without ventral buccal bulb and gizzard-like structure. Nephridia from chaetiger 7 onwards, greenish in life; pairs of nephridia on each chaetiger opening to exterior middorsally via two closely situated nephridiopores. Habitat. Adults of P. hoplura make U-shaped burrows in shells of barnacles, various gastropods and bivalves, including abalone and oysters. Worm burrows appear as detrital tubes inside shells: the walls of the burrows are lined with detritus, and median space of each burrow is also filled with detritus forming a medial wall. Each burrow opens to the outside via two joined apertures forming a characteristic 8-shaped hollow in a shell, and extended by two smooth silty tubes each up to 5 mm long. In Italy and France, adults of P. hoplura were found in shells of live whelk Stramonita haemastoma , European flat oyster Ostrea edulis , Pacific oyster Crassostrea gigas , empty shells of pilgrim scallop Pecten maximus (Linnaeus, 1758), and empty shell of gastropod Ocenebra erinaceus occupied by hermit crab Clibanarius erythropus . The worms were rare and did not cause serious damage to the mollusks. 25-chaetiger individual 50-chaetiger individual chaetiger branchia awl-like sickle-like chaetiger branchia awl-like sickle-like spine spine spine spine 17 42 + In South Korea, P. uncinata (= P. hoplura ) was first recorded in 2004 from the oysters cultivated in Geoje and Goseong (south-eastern part of South Korea), but not found in abalone cultivated in sea cages (Sato-Okoshi et al . 2012). In the present study, we found up to three worms per shell in abalone cultivated in cages in the sea in Wando county, and a maximum of 80 large worms in one shell of abalone cultivated in land-based tanks on Jeju Island (Fig. 4 D). In many cases worms caused formation of dark brown muddy or nacreous, parchment-like blisters on the inner shell surface (Fig. 4 A–C). Heavy infestation by P. hoplura occasionally caused secondary bacterial infestation, clogging of respiratory pores and death of mollusk. In contrast to abalone, shells of the Pacific oyster C. gigas widely cultivated around Geoje Island were rarely infested by P. hoplura which seems to not effect oyster condition. : Published as part of Radashevsky, Vasily I., Choi, Jin-Woo & Gambi, Maria Cristina, 2017, Morphology and biology of Polydora hoplura Claparède, 1868 (Annelida: Spionidae), pp. 543-555 in Zootaxa 4282 (3) on pages 545-550, DOI: 10.11646/zootaxa.4282.3.7, http://zenodo.org/record/827990 : {"references": ["Claparede, E.

Adult morphology (Material from the type locality, Gulf of Naples, Italy) . Neotype (SMF 24359) largest complete individual 30 mm long, 1.5 mm wide with 175 chaetigers; other individuals (MIMB 28148) 8 to 11 mm long, with 60 to 100 chaetigers. Pigmentation absent on body. No pigment on palps in a 60-chaetiger individual, and in an individual 11 mm long with 100 chaetigers; 75-chaetiger individual and neotype with five and seven paired black bands on each palp, respectively. Prostomium anteriorly incised, extending posteriorly to end of chaetiger 3 as a low caruncle. Occipital antenna absent in 60- and 75-chaetiger individuals; larger individuals, including neotype, with short occipital antenna on prostomium. Eyes absent in neotype; up to four eyes present or eyes absent in other individuals. Chaetiger 1 with short capillaries only in neuropodia. Chaetiger 5 with up to four dorsal superior winged capillaries, six heavy falcate spines alternating with bilimbate-tipped companion chaetae, and six ventral winged capillaries; falcate spines with lateral flange. Hooded hooks in neuropodia from chaetiger 7, up to ten in a series, not accompanied by capillaries; hooks bidentate, with constriction on shaft. Posterior notopodia (from chaetiger 155 onwards in a 175-chaetiger neotype) each with 1–2 heavy recurved spines and a tuft of slender capillaries; spines with curved tips directed medially. Branchiae from chaetiger 7 continuing posteriorly along most of body (on chaetigers 7–154 in neotype). Pygidium white, cup-shaped with dorsal gap. Of five individuals, two were females (175-chaetiger neotype with oocytes in chaetigers 40–113), two had no gametes, and one was male (10 mm long with 75 chaetigers, with branchiae on chaetigers 7–39, and nototrochs composed of single rows of cilia) with spermatocytes, tetrads of spermatids and individual spermatozoa (introsperm with elongated head and midpiece, similar to those in other Polydora species) floating in coelom in chaetigers 29–44. Other material from Italy and France. Large worms of a size range similar to specimens from type locality (see above). Black pigment diffused on anterior part of prostomium (in front of eyes) in some individuals, varying from weak only on lateral sides to intense on lateral and dorsal sides of prostomium. Similar pigment of variable intensity diffused on dorso-lateral sides of peristomium in some individuals. Up to ten black paired bands present on each palp and black pigment diffused on pygidium in some individuals. Notopodia of 5–16 posterior chaetigers with heavy recurved spines in addition to capillaries. Pygidium flaring disc with wide dorsal gap. Material from South Korea ( Polydora hoplura in Korean galgori-kin-eolgool-gat-ji-rung-i, meaning a long face worm with hook). Up to 55 mm long and 2 mm wide for 180 chaetigers. Body pale to light tan in life; with numerous glandular cells on dorsal side from chaetigers 10–15 giving dorsum whitish appearance (Fig. 2 A). Remains of larval melanophores present on dorso-lateral sides of 15–16 anterior chaetigers in individuals up to 50– 60-chaetiger stage; larger worms usually lacking black pigment on body. Black narrow longitudinal stripes on lateral sides of anterior part of prostomium and a pair of small black patches on dorsal side of peristomium present in three individuals (of more than one thousand examined). Up to 25 black paired bands present on each palp in individuals with more than 50 chaetigers (Fig. 2 A–D); bands usually regularly arranged and of equal intensity along palp (Fig. 3 A); in some individuals bands more intense and distinct on distal half of palp. Number of bands weakly correlated with total number of chaetigers in an individual (Fig. 3 B). Prostomium with shallow anterior incision often seen only in ventral view, posteriorly extending to end of chaetiger 3 (usually to middle of chaetiger 3) as a low caruncle, shorter in small individuals (Fig. 3 C). Short occipital antenna present on caruncle in individuals with more than 90 chaetigers; smaller individuals usually without antenna. Two pairs of black eyes usually present. Palps as long as 15–30 chaetigers, with longitudinal frontal groove lined with fine cilia, latero-frontal motile compound cilia, and papillae with short non-motile cilia densely arranged in 4–5 rows along both sides of frontal groove (Fig. 2 C), and also sparsely scattered on lateral and abfrontal palp surfaces all along palp length (Fig. 2 D). Chaetiger 1 with short capillaries in neuropodia and small postchaetal lamellae in both rami; notochaetae absent. Notopodia of posterior chaetigers with two kinds of heavy spines in addition to 2–6 slender capillaries (Fig. 2 H). One spine slender and slightly curved, awl-like (Fig. 2 H, sl ), second spine heavily recurved, sickle-shaped (Fig. 2 H, he ); spines with curved tips directed medially. Slender awl-like spines first appearing in chaetiger 18 in juveniles with 18–19 chaetigers, while heavy sickle-shaped spines first appearing in notopodia in juveniles with 25–30 chaetigers (Table 1: 25-chaetiger individual). Both kinds of spines beginning from more posterior chaetigers in larger individuals (Fig. 3 D) what can only be explained by their falling out from anterior notopodia with growth of worms. Slender awl-like spines and heavy sickle-shaped spines developing and falling out at different rates and, therefore, arranged in notopodia differently (Table 1). In notopodia of new segments developing in growth zone in front of pygidium in worms with more than 25 chaetigers, capillaries and heavy sickle-shaped spines developing first while slender awl-like spines developing later. Consequently, notopodia of a few posteriormost chaetigers bearing only capillaries and heavy sickle-shaped spines. With growth, heavy sickle-shaped spines of anteriormost spine-bearing notopodia falling out first while slender awl-like spines falling out gradually afterwards. Consequently, notopodia of a few anteriormost chaetigers bearing only capillaries and slender awl-like spines. Middle spine-bearing notopodia having both kinds of spines in addition to capillaries. Anterior position of spines correlated with arrangement of branchiae (Table 1). In small individuals, spines first present from 4–17 chaetigers after last branchiate chaetiger. In mid-size individuals, slender awl-like spines usually from last branchiate chaetiger and heavy sickle-shaped spines usually beginning 1–3 chaetigers after last branchiate chaetiger. In large individuals, slender awl-like spines usually from 1–3 chaetigers before last branchiate chaetiger, while heavy sickle-shaped spines usually beginning in last branchiate chaetiger or in next chaetiger after it. Chaetiger 5 twice as large as chaetigers 4 and 6, with up to six dorsal superior winged capillaries, seven heavy falcate spines arranged in a slightly curved diagonal row and alternating with bilimbate-tipped companion chaetae, and seven ventral winged capillaries. Dorsal superior and ventral capillaries shorter and fewer than those on adjacent chaetigers. Falcate spines with large subdistal flange on lateral side; upper and inner parts of flange thinner than lower and outer parts, thus in newly developed spines (situated in posterior part of spine row) whole structure appearing as a large tooth joined to main fang by thin sheath; in older spines (situated in anterior part of spine row) lateral flange greatly worn and indistinct. Hooks in neuropodia from chaetiger 7, up to 12 in a series, not accompanied by capillaries. Hooks bidentate; shaft slightly curved, with weak constriction in upper part (Fig. 2 G). Branchiae from chaetiger 7, full-sized from chaetigers 10–12, gradually diminishing in size along posterior half of body, absent on 5–20 posteriormost chaetigers (Fig. 3 D). Branchiae flattened, with surfaces oriented parallel to body axis, free from notopodial postchaetal lamellae, with longitudinal row of cilia along inner surface. Nototrochs from chaetigers 7–8 onwards, each composed of one row of short cilia, on branchiate chaetigers extending onto branchiae. Pygidium disk-like to cup-shaped, usually with distinct dorsal gap, white due to numerous striated glandular cells (Fig. 2 F). Glandular pouches in neuropodia from chaetiger 6 in individuals with up to about 30 chaetigers, from chaetiger 7 in larger individuals; pouches large in chaetigers 7–9 and considerably smaller in successive chaetigers. Digestive tract without ventral buccal bulb and gizzard-like structure. Nephridia from chaetiger 7 onwards, greenish in life; pairs of nephridia on each chaetiger opening to exterior middorsally via two closely situated nephridiopores. Habitat. Adults of P. hoplura make U-shaped burrows in shells of barnacles, various gastropods and bivalves, including abalone and oysters. Worm burrows appear as detrital tubes inside shells: the walls of the burrows are lined with detritus, and median space of each burrow is also filled with detritus forming a medial wall. Each burrow opens to the outside via two joined apertures forming a characteristic 8-shaped hollow in a shell, and extended by two smooth silty tubes each up to 5 mm long. In Italy and France, adults of P. hoplura were found in shells of live whelk Stramonita haemastoma , European flat oyster Ostrea edulis , Pacific oyster Crassostrea gigas , empty shells of pilgrim scallop Pecten maximus (Linnaeus, 1758), and empty shell of gastropod Ocenebra erinaceus occupied by hermit crab Clibanarius erythropus . The worms were rare and did not cause serious damage to the mollusks. 25-chaetiger individual 50-chaetiger individual chaetiger branchia awl-like sickle-like chaetiger branchia awl-like sickle-like spine spine spine spine 17 42 + In South Korea, P. uncinata (= P. hoplura ) was first recorded in 2004 from the oysters cultivated in Geoje and Goseong (south-eastern part of South Korea), but not found in abalone cultivated in sea cages (Sato-Okoshi et al . 2012). In the present study, we found up to three worms per shell in abalone cultivated in cages in the sea in Wando county, and a maximum of 80 large worms in one shell of abalone cultivated in land-based tanks on Jeju Island (Fig. 4 D). In many cases worms caused formation of dark brown muddy or nacreous, parchment-like blisters on the inner shell surface (Fig. 4 A–C). Heavy infestation by P. hoplura occasionally caused secondary bacterial infestation, clogging of respiratory pores and death of mollusk. In contrast to abalone, shells of the Pacific oyster C. gigas widely cultivated around Geoje Island were rarely infested by P. hoplura which seems to not effect oyster condition. : Published as part of Radashevsky, Vasily I., Choi, Jin-Woo & Gambi, Maria Cristina, 2017, Morphology and biology of Polydora hoplura Claparède, 1868 (Annelida: Spionidae), pp. 543-555 in Zootaxa 4282 (3) on pages 545-550, DOI: 10.11646/zootaxa.4282.3.7, http://zenodo.org/record/827990 : {"references": ["Claparede, E.
