Chone veleronis Banse, 1972 [LACM-AHF POLY 0460, paratypes].</p> <p>Description (based on paratypes, in parentheses variation of specimens from Phase II)</p> <p>Colour, body shape, and size. Body cream coloured; each thoracic and anterior abdominal segment has two yellow-whitish glandular ridges; glandular ridge in chaetiger 2 brownorange. Body red-brown in life with whitish glandular rings (Banse 1972). Trunk cylindrical, posterior abdomen depressed dorso-ventrally (Figure 1D). Body length 5– 14 mm (2.5–21), width 0.3–1.5 mm (0.25–1.5). Tubes unknown.</p> <p>Branchial lobes and branchial crown. Insertion of the branchial crown not exposed beyond collar (Figure 1A). Branchial crown length 5–7.5 mm (2–10). Radioles: seven to eight pairs (five to ten). Radioles with median pinnules two times longer than more proximal pinnules. Radiolar tips long. The palmate membrane extends three-quarters the length of the branchial crown (it almost reaches the radiolar tips). Lateral flanges broad (Figure 1G). Dorsal lips triangular, erect, without mid-rib. Ventral lips rounded, about three-quarters the length of the dorsal lips. Ventral radiolar appendages: one pair, as long as branchial crown.</p> <p>Peristomium. Anterior peristomial ring lobe not exposed beyond collar, distally entire, triangular. Posterior peristomial ring collar: dorsal, ventral and lateral margins entire (Figure 1A–C), ventral margin higher than dorsal (Figure 1C), entire length of mid-dorsal collar margins forms a narrow gap (Figure 1A). Ventral shield of collar rounded, with an anterior, small whitish triangle, and two postero-lateral grooves (Figure 1B, C). Ratio of posterior peristomial ring collar length versus chaetiger 2 length, in lateral view: 2.5:1.</p> <p>Thorax. Chaetiger 1: two groups of elongate, narrowly hooded chaetae. Chaetigers 2–8: notopodia—two irregular rows of elongate, narrowly hooded chaetae; one anterior row with bayonet chaetae; two posterior rows with symmetrical; paleate chaetae with medium-sized mucro (Figure 1I, J); neuropodia—one row of acicular uncini per torus, main fang surmounted by four rows of teeth equal in size, occupying half of the main fang length (Figure 1H). Pre- and post-chaetal lobes well developed. Glandular ridge on chaetiger 2 (gr2): narrow dorsally (Figure 1A), broad ventrally (Figure 1B); in dorsal view it almost reaches the anterior margin of the intra-notochaetal groove (Figure 1A).</p> <p>Abdomen. Abdominal segments: 31–48 (26–47). Anterior segments: two transverse rows of elongate, narrowly hooded chaetae, chaetae from upper row half as long as chaetae in lower row; uncini with the main fang surmounted by five regular rows of teeth in frontal view, equal in size, occupying one-half the length of main fang, main fang not extending beyond breast, breast rectangular (Figure 1E). Posterior segments: 1–2 very elongate, narrowly hooded chaetae, 25% longer than in anterior segments; modified uncini with the main fang surmounted by six to seven regular vertical rows of teeth equal in size, occupying three-quarters the length of main fang, main fang not extending beyond breast, breast rectangular (Figure 1F). Pygidium with triangular posterior margin (Figure 1D).</p> <p>Methyl green staining. The anterior margin of the collar is not coloured; the posterior half of the collar is darker than anterior half; anterior half with grooves and dark spots, the triangle above the ventral shield is not coloured. Thorax and anterior abdomen with epidermis completely glandular, stains uniformly, dorsally (Figure 1A), ventrally (Figure 1B), and laterally (Figure 1C). Posterior end with dark glands (Figure 1D). After 1 day, body stays stained, except the posterior abdomen.</p> <p>Gametes. Paratypes immature.</p> <p>Remarks</p> <p>Chone albocincta, C. veleronis, and C. eiffelturris n. sp. (see below) are distinguished from other species of the genus by the whitish segmental rings in the thorax and anterior abdomen (Table II). Chone albocincta can be distinguished from C. veleronis and C. eiffelturris n. sp. by the following: the glandular ridge on the second chaetiger is broad ventrally, dorsally it extends to the anterior margin of the intra-notochaetal groove (ventrally greatly broadened extending into the third chaetiger, dorsally narrow in C. veleronis; narrow, same width in C. eiffelturris n. sp.); the ventral shield of collar is rounded with an anterior whitish triangle and two postero-lateral grooves (ventral shield of collar horseshoe-shaped, three times longer than wide in C. veleronis; 2.5 times longer than wide in C. eiffelturris n. sp.); short branchial lobes in C. albocincta and C. eiffelturris n. sp. (long in C. veleronis).</p> </div>	https://treatment.plazi.org/id/03B1879F30235C4FFDD9E059C733FC0B	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

Holotype partially dehydrated, preserved body brown (bright orange-red when freshly preserved fide Johnson 1901), with iridescent, rounded small spots in anterior thoracic segments (Figure 2A, C). Trunk cylindrical (Figure 2C), abruptly enlarged in posterior part of abdomen (Figure 2F). Holotype complete, branchial crown regenerating (Figure 2A, C). Body length 74 (51–85) mm, width 4 (3–8) mm.</p> <p>Branchial lobes and branchial crown. Insertion of the branchial lobes not exposed beyond collar. Branchial crown length 4 mm (12–17). Radioles: 17 pairs (25–27). Radioles with median pinnules two times longer than proximal pinnules. Radiolar tips short (Figure 2J). The palmate membrane extends about three-quarters the length of branchial crown. Lateral flanges broad (Figure 2H, J). Dorsal lips broadly rounded in frontal view, as long as wide, without mid-rib, resembling the ventral lips, longer than wide in dorso-lateral view. Dorsal pinnular appendages: (two pairs) united by a palmate membrane (pm) (Figure 2I). Ventral lips rounded, as long as wide, about one-quarter the length of dorsal lips. Ventral radiolar appendages: (eight short pairs).</p> <p>Peristomium. Anterior peristomial ring lobe not exposed beyond collar, distally entire, triangular. Posterior peristomial ring collar: antero-dorsal margins entire (Figure 2A, D), forming two well-developed dorsal pockets; entire length of mid-dorsal collar margins forms a narrow gap; faecal groove broad, V-shaped, from segment of collar to segment 2 (Figure 2A); lateral and ventral margins entire (Figure 2B, C, E); ventral margin higher than dorsal. Ventral shield of collar swollen, horseshoe-shaped, as wide as long (Figure 2B, E). Ratio of posterior peristomial ring collar length versus chaetiger 2 length, in lateral view: 2.5:1 (Figure 2C).</p> <p>Thorax. Chaetiger 1: two groups of eight elongate, narrowly hooded chaetae. Chaetigers 2– 8: notopodia—two rows of elongate, narrowly hooded chaetae (Figure 2O); one anterior row with bayonet chaetae, two posterior rows with symmetrical, paleate chaetae with a very short mucro, sometimes minute or not discernible (Figure 2L–N); neuropodia—two irregular rows of 25 acicular uncini per torus, facing in the same direction, the oldest upper parts of the tori have only one row (one-quarter the length of tori), main fang surmounted by six rows of teeth, second tooth enlarged, located in the midline; dentition covering one-quarter the main fang length (Figure 2K). Glandular ridge on chaetiger 2: narrow.</p> <p>Abdomen. Abdominal segments: 63 (58–64). Anterior segments: two transverse rows of elongate, narrowly hooded chaetae, chaetae from upper row 50% shorter than chaetae in lower one; uncini with the main fang surmounted by four rows of teeth equal in size, occupying one-half the length of main fang, older (dorsalmost) uncini smaller than younger uncini (ventralmost), main fang not extending beyond breast, breast rectangular</p> <p>(Figure 2P). Posterior segments: one or two very elongate, narrowly hooded chaetae; uncini similar to those in anterior abdomen (Figure 2Q). Pygidium pointed (Figure 2F).</p> <p>Gametes. Holotype without gametes; females with oocytes in thorax (RBCM 985-403 - 4) and abdomen (USNM 43637).</p> <p>Methyl green staining. The entire body turns uniformly green. The anterior half of the collar is not coloured, posterior end dark. Anterior half of the ventral shield of collar not coloured, posterior half dark.</p> <p>Remarks</p> <p>Megachone was synonymized in Chone by Banse (1972) by the presence of spatulate chaetae in the type species. Banse (1972) recorded irregular orange-red spots in collar and anterior segments in the holotype. These spots are actually whitish and iridescent.</p> <p>Chone aurantiaca, C. gracilis, C. magna, C. mollis, C. picta, and the type species (C. infundibuliformis) constitute a group of species (Group I) that have anterior and posterior abdominal uncini of similar shape (Table III). This is in contrast with a second group (Group II) in which the posterior abdominal uncini are modified (Table II).</p> <p>Chone aurantiaca, C. farringtonae, and C. magna have a long posterior peristomial ring collar: in C. aurantiaca and C. farringtonae it is 2.5 times as long as second chaetiger (three times longer in C. magna). Chone aurantiaca and C. magna have uniform abdominal uncini throughout and narrow glandular ridge on chaetiger 2 (posterior abdominal uncini modified and broad glandular ridge in C. farringtonae). Chone aurantiaca can be distinguished from C. magna by having short radiolar tips (long in C. magna), broad radiolar flanges (narrow in C. magna), and ventral shield of collar horseshoe-shaped (rounded in C. magna).</p> <p>In the case of Chone aurantiaca, C. mollis (Figure 19B), and C. infundibuliformis the glandular ridge occupies only the external half of the ventral glandular epithelium; whereas dorsally, the glandular ridge occupies only a very small area. For Chone aurantiaca and C. infundibuliformis, Tovar-Hernández and Sosa-Rodríguez (2006) determined that the glandular ridge is composed of strongly differentiated acidophil glandular cells, tubularshaped with granulose secretions. From both taxonomic and systematic standpoints, it is recommended that the characterization of the external shape and the extension within the epithelium of the glandular ridge be taken into account as species diagnostic characters.</p> <p>Chone bimaculata Banse and Nichols, 1968</p> <p>(Figure 3)</p> <p>Chone bimaculata Banse and Nichols 1968, p 227 –229, Figure 2a–j.</p> <p>Material examined</p> <p>Type material.

Posterior peristomial ring collar: antero-dorsal margin forming two welldeveloped dorsal pockets, entire length of mid-dorsal collar margins forms a narrow gap (Figure 7B); lateral, dorsal, and ventral margins entire (Figure 7A–C); ventral margin higher than dorsal (Figure 7C). Ventral shield of collar Eiffel Tower-shaped, swollen, 2.5 times longer than wide (Figure 7A). Ratio of posterior peristomial ring collar length versus chaetiger 2 length, in lateral view: 2.5:1.</p> <p>Thorax. Chaetiger 1: two groups of elongate, narrowly hooded chaetae. Chaetigers 2–8: notopodia—two irregular rows of elongate, narrowly hooded chaetae; one anterior row with bayonet chaetae; two posterior rows with five symmetrical, paleate chaetae with minute mucro (Figure 7I); neuropodia—one row of acicular uncini per torus, main fang surmounted by four rows of teeth equal in size, second tooth enlarged, located offset midline, dentition occupying three-quarters of main fang length (Figure 7L). Pre- and postchaetal lobes well developed. Glandular ridge on chaetiger 2 (gr2): narrow. Very narrow glandular ridges (gr) in thoracic segments.</p> <p>Abdomen. Abdominal segments: 53 (43–51). Anterior segments: two transverse rows ofelongate, narrowly hooded chaetae, chaetae from upper row half as long as chaetae in lower row; uncini with the main fang surmounted by three regular rows of teeth in frontal view, second tooth enlarged, dentition occupying half the length of main fang (Figure 7J), main fang not extending beyond breast, breast rectangular; single, narrow glandular ridge per segment, more evident than those in thorax. Posterior segments: one or two very elongate, narrowly hooded chaetae, directed upwards, modified uncini with the main fang surmounted by six to seven regular vertical rows of teeth equal in size (Figure 7K), occupying three-quarters the length of main fang, main fang not extending beyond breast, breast rectangular.

Posterior end with a granular pattern (Figure 7A).</p> <p>Gametes. Paratype and specimen from [LACM-AHF 003249, 6762] females with abundant polygonal oocytes in all thoracic segments and anterior abdomen, diameter 115–150 mm.</p> <p>Etymology</p> <p>The specific name refers to the peculiar shape of the ventral shield of the collar, which is Eiffel Tower-shaped. Derived from the Latin turris, meaning tower.</p> <p>Remarks</p> <p>Chone eiffelturris n. sp., C. paramollis n. sp., C. aurantiaca, C. magna, C. mollis, and C. picta have paleate chaetae with a minute mucro, not easily discernible (Tables II, III). However, Chone eiffelturris n. sp. and C. paramollis n. sp. have the modified posterior abdominal uncini typical of Group II, in comparison with C. aurantiaca, C. magna, C. mollis, and C. picta the abdominal uncini are of similar shape throughout (Group I). Chone eiffelturris n. sp. has extremely long radiolar tips (long in C. paramollis n. sp.); the palmate membrane extends more than three-quarters the length of branchial crown, almost reaching radiolar tips (three-quarters in C. paramollis n. sp.); ventral shield of collar is Eiffel Tower-shaped (horseshoe-shaped in C. paramollis n. sp.) and glandular ridges are present in thorax and anterior abdominal segments (absent in C. paramollis n. sp.). Chone eiffelturris n. sp. is unique in having extremely long radiolar tips, ventral shield of collar Eiffel Tower-shaped and glandular ridges in thorax and anterior abdomen. Other species with glandular ridges in thorax and anterior abdomen are Chone albocincta and C. veleronis (see remarks on C. albocincta). Chone mollis and Chone eiffelturris n. sp. are species with wide distribution in California, Western Mexico, and the Pacific coast of Panama.</p> </div>	https://treatment.plazi.org/id/03B1879F30355C51FE3EE6C7C56FFD23	Public Domain	No known copyright restrictions apply.

The species of Moore is a senior homonym [according to the Principle of Homonym (Article 52.2) and the Principle of Priority (Article 52.3) from the International Commission on Zoological Nomenclature 2000]. It may be used as a valid name. The holotype of Chone gracilis has the ventral margin of the collar incised probably, due to a regeneration process. However, in paratype and additional material it is entire. Deep-water specimens from Oregon have abdominal elongate narrowly hooded chaetae, extremely long. Chone gracilis is unique among the species of Chone distributed in North American waters in having medium-length radiolar tips. Among species in Group I, Chone gracilis and C. infundibuliformis have a short mucro; however, the ventral margin of the collar is higher than dorsal margin in C. gracilis, and slightly higher in C. infundibuliformis.</p> </div>	https://treatment.plazi.org/id/03B1879F30385C53FE17E4FEC700FA43	Public Domain	No known copyright restrictions apply.

Body cream coloured, collar yellow, ventral shield of collar and ventral thoracic segments whitish, glandular ridge on chaetiger 2 white, iridescent epicuticle; ventral and dorsal lips red; radioles with six to eight irregular red-brown coloured, narrow bands [LACM-AHF, Tomales Bay, June 2004, LH 04-286-001].</p> <p>Branchial lobes and branchial crown. Insertion of the branchial lobes not exposed beyond collar. Branchial crown length 8 mm (8–10). Radioles: 17 pairs (13–16). Pinnules from middle region twice as long as more proximal pinnules. Radiolar tips long, elongate (Figure 10G). The palmate membrane extends to three-quarters the length of branchial crown. Lateral flanges broad. Dorsal lips broadly rounded in frontal view, as long as wide, without a mid-rib, resembling the ventral lips. Dorsal pinnular appendages: (five to eight) short pairs united by a palmate membrane. Ventral lips rounded, as long as wide, about one-half of the dorsal lips length. Ventral radiolar appendages (vra): one to five pairs, onequarter to one-half the length of branchial crown (Figure 19B).</p> <p>Peristomium. Base of the peristomium composed of two lateral horns of basal central skeleton (bcs) surrounding the mouth (mo); anterior peristomial ring lobe (lo) exposed beyond collar, distally triangular, elongate (Figure 10B–D, F). The base of the posterior peristomial ring collar is supported by basal lateral skeleton (bls). Antero-dorsal, lateral, and ventral margins of the posterior peristomial ring collar entire (Figure 10A–D); ventral margin slightly higher than dorsal (Figure 10C); entire length of mid-dorsal margins forms a narrow gap; dorsal pockets well developed. Ventral shield of collar swollen, inside and outside of the collar wall (Figure 10B), horseshoe-shaped, two times wider than long (Figure 10B, D), divided by a median-longitudinal line in large specimens (Figure 10B). Ratio of posterior peristomial ring collar length versus chaetiger 2 length, in lateral view: 2:1.</p> <p>Thorax. Chaetiger 1: elongate, narrowly hooded chaetae. Chaetigers 2–8: notopodia—two rows of elongate, narrowly hooded chaetae; one anterior row with bayonet chaetae (Figure 10M), two posterior rows with paleate chaetae with minute mucro, not easily discernible (Figure 10H–K); neuropodia—one row of acicular uncini, main fang surmounted by five rows of teeth equal in size, second tooth enlarged, located in the midline, dentition occupying a quarter the length of main fang (Figure 10L). Pre- and postchaetal lobes well developed. Broad glandular, columnar epithelium (gce), swollen in first two ventral thoracic segments, narrow in following thoracic segments (Figure 19B). Narrow glandular ridge on chaetiger 2, it occupies a quarter of the epithelium in longitudinal section (Figure 19B).</p> <p>Abdomen. Abdominal segments: 42 (41–43), two transverse rows of five to six elongate, narrowly hooded chaetae, chaetae from upper row half as long as chaetae in lower one; uncini with the main fang surmounted by four regular vertical rows of teeth equal in size, occupying one-half the length of main fang, older (dorsalmost) uncini smaller than younger uncini (ventralmost), main fang not extending beyond breast (Figure 10N), breast rectangular. Posterior segments: one or two very elongate, narrowly hooded chaetae; uncini similar to those in anterior abdomen (Figure 10O). Pygidium with rounded posterior margin (Figure 10E).</p> <p>Gametes. Holotype and specimens from Pacific Panama females with oocytes (oo) in thorax (Figure 19B).</p> <p>Methyl green staining. The epidermis is completely glandular and stains uniformly in thorax and abdomen, dorsally and ventrally (Figure 10A–C). The ventral shield of collar is not coloured in the anterior margin (Figure 10B, D). Posterior end with granular pattern (Figure 10E).</p> <p>Remarks</p> <p>Metachone mollis was established as having thoracic paleate chaetae lacking a mucro; however, Fauvel (1927) transferred this species to Chone, arguing that because the size and length of the mucro varies greatly between species it cannot have generic significance. Reexamination of type material confirmed the presence of a very short hair-like mucro in complete chaetae in holotype. Chone aurantiaca, C. magna, C. picta, and C. mollis have paleated chaetae with mucro minute or absent (Table III). In C. mollis, the ratio of posterior peristomial ring collar length versus chaetiger 2 length is 2:1 (2.5: 1 in C. aurantiaca, 3: 1 in C. magna and C. picta); the ventral margin of the posterior peristomial ring collar is slightly higher than dorsal (very much higher in C. aurantiaca, C. magna, and C. picta); the radiolar flanges are narrow (broad in C. aurantiaca); and the entire length of mid-dorsal margins forms a narrow gap (broad C. magna and C. picta). Like Chone eiffelturris n. sp., C. mollis is distributed in California, Western Mexico, and Pacific coast of Panama.</p> </div>	https://treatment.plazi.org/id/03B1879F303D5C69FE6EE254C5F0FB65	Public Domain	No known copyright restrictions apply.

Trunk depressed dorso-ventrally, posterior abdomen with a dorso-ventral depression (Figure 11E). Body length 20 mm (13–24), width 1 mm (0.9–1). Tubes unknown.</p> <p>Branchial lobes and branchial crown. Insertion of branchial lobes not exposed beyond collar (Figure 11A, B). Branchial crown length 5 mm (4). Radioles: eight pairs (seven to eight). Radioles with median pinnules twice the length of proximal pinnules. Radiolar tips long (Figure 11G). The palmate membrane extends to three-quarters the length of branchial crown. Lateral flanges narrow. Dorsal lips (dl) triangular, elongate, erect, without mid-rib (Figure 11F). Dorsal pinnular appendages: two pairs. Ventral lips rounded, as long as wide, about one-quarter the length of dorsal lips. Ventral radiolar appendages: one pair, occupying one-half the length of branchial crown.</p> <p>Peristomium. Anterior peristomial ring lobe triangular at their base, then digitiform, not exposed beyond collar. Posterior peristomial ring collar: antero-dorsal margin forming well-developed dorsal pockets, entire length of mid-dorsal collar margins forms a narrow gap (Figure 11C); lateral and ventral margins entire (Figure 11A, B, D); ventral margin slightly higher than dorsal (Figure 11B). Ventral shield of collar horseshoe-shaped, swollen, as wide as long (Figure 11D). Ratio of posterior peristomial ring collar length versus chaetiger 2 length, in lateral view: 2:1.</p> <p>Thorax. Chaetiger 1: elongate narrowly hooded chaetae. Chaetigers 2–8: notopodia—two irregular rows of elongate, narrowly hooded chaetae; one anterior row with bayonet chaetae (Figure 11O); two posterior rows with five symmetrical, paleate chaetae with minute or indiscernible mucro (Figure 11H, I); neuropodia—one row of acicular uncini per torus, main fang surmounted by four rows of teeth equal in size, second tooth enlarged, located offset midline, dentition occupying three-quarters the length of main fang (Figure 11J). Pre- and post-chaetal lobes well developed. Glandular ridge on chaetiger 2: narrow.</p> <p>Abdomen. Abdominal segments: 46 (37–43). Anterior segments: two transverse rows of elongate, narrowly hooded chaetae, chaetae from upper row half as long as chaetae in lower row; uncini with the main fang surmounted by three regular rows of teeth in frontal view, second tooth enlarged, dentition occupying half the length of main fang, main fang not extending beyond breast, breast rectangular (Figure 11K, L). Posterior segments: one or two very elongate, narrowly hooded chaetae, modified uncini with the main fang surmounted by six to seven regular vertical rows of teeth equal in size, occupying threequarters the length of main fang, main fang not extending beyond breast, breast rectangular (Figure 11M, N).

Ventral radiolar appendages: one to three pairs, the inner one as long as three-quarters the length of branchial crown, the remainder about one-quarter the length of branchial crown.</p> <p>Peristomium. Anterior peristomial ring lobe exposed beyond collar (Figure 13B–D), distally bilobed (Figure 13D, F). Posterior peristomial ring collar: antero-dorsal margin deeply incised, forming two well-developed dorsal pockets (Figure 13A), two dorsal, oval glandular shields (ogs) (Figure 13A, B), entire length of mid-dorsal collar margins forms a narrow gap (Figure 13A); lateral and ventral margins entire (Figure 13C, D); ventral margin slightly higher than dorsal (Figure 13B, C). Ventral shield of collar swollen, horseshoe-shaped, two times wider than long (Figure 13D). Ratio of posterior peristomial ring collar length versus chaetiger 2 length, in lateral view: 2:1.</p> <p>Thorax. Chaetiger 1: two groups of four to six elongate, narrowly hooded chaetae. Chaetigers 2–8: notopodia—two irregular rows of four to five elongate, narrowly hooded chaetae; one anterior row with four to five bayonet chaetae (Figures 13I, 14D, F); two posterior rows with five symmetrical, paleate chaetae with long mucro (Figures 13J–L, 14D, E); neuropodia—one row of 8–13 acicular uncini per torus, main fang surmounted by four rows of teeth equal in size, occupying half the length of main fang (Figures 13H, 14A). Pre- and post-chaetal lobes well developed. Broad glandular, columnar epithelium (gce), swollen in ventral thoracic segments (Figure 19C). Broad glandular ridge on chaetiger 2, occupying half of the epithelium in longitudinal section (Figure 19C).</p> <p>Abdomen. Abdominal segments: 46 (42–46). Anterior segments: two transverse rows of five to six elongate, narrowly hooded chaetae (Figure 13M, V), chaetae from upper row half as long as chaetae in lower row (Figure 14G); 10–12 uncini per torus, older (dorsalmost) and younger uncini (ventralmost) with the main fang surmounted by six regular rows of teeth in frontal view, equal in size, occupying three-quarters the length of main fang (Figure 14B), main fang not extending beyond breast (Figure 14O), breast rectangular. Posterior segments: one or two very elongate, narrowly hooded chaetae, 25% longer than in anterior segments (Figure 14H), making a small angle with the shaft at the base of the hood (Figure 13N, U); five to eight modified uncini per torus with the main fang surmounted by six to seven regular vertical rows of teeth equal in size (Figure 14C), occupying threequarters the length of main fang, older (dorsalmost) uncini smaller than younger uncini (ventralmost), main fang not extending beyond breast, breast rectangular. Ventral, glandular, whitish band on posterior abdomen (gb) (Figure 13G). Pygidium with triangular posterior margin (Figure 13G).</p> <p>Gametes. Females with oocytes polyhedron-shaped in thorax and abdomen (Figure 15B), diameter 37.5–56.25 mm. Sperm in posterior abdominal chaetigers, spermatozoa rectangular nucleus (two times longer than wide), acrosome sucking-shaped (occupying one-quarter the length of nucleus) and two small, rounded mitochondria.</p> <p>Methyl green staining. Anterior end of the ventral shield of collar not coloured, posterior end dark. Dorsally, there is no colour in collar, chaetigers 1 and 2; then each segment is divided into four dark rectangles by the presence of the faecal groove, inter-segmental and intra-notochaetal and neurochaetal grooves. Ventrally, each segment has a median, longitudinal dark band; lateral sides are coloured uniformly. Laterally, the collar has two large, rectangular spots (Figure 13C). Pygidium stays darker for several days.</p> <p>Histology. The ventral, posterior abdominal glandular band (gb) in Chone quebecensis n. sp. is a complete whitish band in preserved material (Figure 13G), pink with haematoxylin–eosin (Figure 15A). This structure is located in a mid-ventral transition zone on the columnar epithelium (Figure 15A, C, E, F), and composed of strongly differentiated acidophil glandular cells (ag), tubular-shaped with granulose secretions (Figure 15F). The glandular columnar epithelium (gce) has large, rectangular cells, covered by cuticle (cu) (Figure 15E). Abdomen is composed of two ventral (vplm) and two dorsal packages of longitudinal muscle (dplm) (Figure 15A, D); the coelom is filled with oocytes (oo) and yolk (y) (Figure 15B).</p> <p>Remarks</p> <p>Chone quebecensis n. sp. is unique among Chone species in having (1) the ventral margin of anterior peristomial ring lobe distally bilobed; (2) two peristomial, dorsal glandular shields; (3) a ventral, longitudinal glandular band on the posterior part of abdomen; and (4) spermatozoa with rectangular nucleus (two times longer than wide), head suckershaped and two small, rounded mitochondria. The bilobed condition of the anterior peristomial ring lobe in Chone quebecensis n. sp. is common in species of Amphicorina Claparède, 1864 (in which it could be minutely bilobed or trilobed), and also in C. bimaculata and C. sp. 3 Fitzhugh, 2002 (bilobed in both). However, C. quebecensis n. sp. is easily distinguished from C. bimaculata and C. sp. 3 by having two peristomial, dorsal glandular shields and a ventral, longitudinal glandular band on the posterior part of abdomen.</p> <p>Chone quebecensis n. sp., C. albocincta, and C. perkinsi have the glandular ridge on chaetiger 2 broad on one side: broad ventrally in C. quebecensis n. sp. and C. albocincta, and broad dorsally in C. perkinsi. Paleate chaetae with long mucro in C. quebecensis sp. nov. and C. perkinsi, with medium-sized mucro in C. albocincta. C. perkinsi has radioles with five to six dark brown bands, each band constituted by a variable number of bright, brownish spots surrounding the cells of the branchial skeleton; these bands are absent in C. quebecensis n. sp. Branchial lobes are exposed beyond the collar in C. quebecensis n. sp., and not exposed in C. perkinsi.</p> <p>Chone quebecensis n. sp. and C. letterstedti have the antero-dorsal margin of the posterior peristomial ring collar deeply incised. Chone quebecensis n. sp. has long radiolar tips (short in C. letterstedti); narrow flanges (broad in C. letterstedti); posterior abdominal uncini modified (not modified in C. letterstedti); and a posterior dorso-ventral abdominal depression (absent in C. letterstedti).</p> <p>Etymology</p> <p>The specific epithet refers to the collecting and distribution zone.</p></div> 	https://treatment.plazi.org/id/03B1879F30065C62FE31E236C5B6FA92	Public Domain	No known copyright restrictions apply.

Each thoracic segment is uniformly coloured ventrally (Figure 18A); laterally, each segment has a dark rectangle in the upper and lower side of the torus (Figure 18B); dorsally, colourless.</p> <p>Remarks</p> <p>In this study, a lectotype and two paralectotypes are designated from syntypes according to Article 74.4, International Commission on Zoological Nomenclature (2000). Chone princei is redescribed and transferred to the genus Jasmineira due to the fact that the original description lacked some critical details diagnostic for Jasmineira. The redescription provided here shows that in J. princei: (1) insertion of the branchial lobes is exposed beyond collar; (2) pinnules are similar-sized along radioles; (3) palmate membrane is absent; (4) radiolar flanges are narrow; (5) dorsal lips are elongate, triangular with radiolar appendages; (6) dorsal pinnular appendages are absent; (7) anterior peristomial ring lobe is not exposed beyond collar; (8) dorsal pockets are well developed with vascular loops in the peristomium; (9) abdominal uncini have the main fang covered by teeth of equal size, breast reduced to narrow swelling, and handles long; and (10) oocytes are distributed in thorax and anterior abdomen.</p> <p>Jasmineira is often confused with Fabrisabella Hartman, 1969, because both have abdominal uncini with a reduced narrow breast and long handle; however, they differ in that Fabrisabella lacks dorsal pinnular appendages and bayonet chaetae; both are present in Jasmineira (Fitzhugh 1989).</p> <p>McIntosh (1916), in his description of Chone princei, referred to a ‘‘glandular tubular organ’’ located at the dorsal peristomium; this structure is called ‘‘vascular loops’’ in the redescription given here. The vascular loops are circular cameras situated dorsally in each side of the peristomium; inside each camera there is an S- or C-shaped vessel; their structure and function has not been studied yet, but it is very probable that they are vascularized by the central blood vessel. The vascular loops have also been recorded in the genus Fabrisabella (Fitzhugh 1989), and in some specimens of Euchone analis (Figure 18O).</p> </div>	https://treatment.plazi.org/id/03B1879F30115C7AFE84E4BBC715F9AE	Public Domain	No known copyright restrictions apply.

North West Territories [CMN 1900-8369 (holotype) Hudson Strait, King George’s Sound, 62 ° N, 73 ° W, 64.3 m, coll. Low and Wakeham, Diana Expedition, September 1897].</p> <p>Additional material. Chone infundibuliformis KrØyer, 1856 [ZMUC POL-1749, lectotype; USNM-376, paralectotype; BMNH 82.5.12.33, paralectotype].</p> <p>Description</p> <p>Holotype dried out, complete but torn in thorax and abdomen. Branchial crown as long as half of the body length. Insertion of the branchial lobes exposed beyond collar, anterior peristomial ring lobe triangular, exposed beyond collar. Ventral margin of collar higher than dorsal. Dorsal margins forming two deep pockets. Radioles with broad flanges, radiolar tips short. Ventral shield of collar swollen. Thoracic uncini distributed as irregular double rows in tori, four rows of teeth above the main fang, hood present (Figure 18I). Bayonet chaetae (Figure 18H). Anterior abdominal uncini with four to five rows of teeth above the main fang, occupying half the length of main fang, main fang not extending beyond breast, breast rectangular (Figure 18J, K), posterior abdominal uncini similar to the anterior ones, but smaller (Figure 18L, M). Pygidium rounded (Figure 18N). Holotype female with oocytes in thorax.</p> <p>Remarks</p> <p>Holotype is dried out, no additional material is available, and there are no new records of this species since its description in 1920. From the holotype, only a few characters were recognized, two of them also being present in C. infundibuliformis. Chone ungavana and C. infundibuliformis have short radiolar tips, broad flanges and thoracic uncini distributed in two irregular rows in each torus. However, in C. ungavana the anterior peristomial ring lobe is exposed beyond the collar (not exposed in C. infundibuliformis), and branchial lobes exposed beyond the collar (not exposed in C. infundibuliformis). At this time it is not possible to recognize the validity of C. ungavana due to the dehydration of the only available material.</p> </div>	https://treatment.plazi.org/id/03B1879F30135C7CFEB9E07AC762FDEB	Public Domain	No known copyright restrictions apply.
