03C687A0FFFDFF88FF35FE55FCF2A255.taxon	discussion	Remarks. No cilia are visible in the branchiae of the holotype and the larger paratypes. The smaller paratypes have branchiae with ventral tufts of cilia (Fig. 4 J). The smallest (non-type) specimens have branchiae without cilia. The development of a dorsal ridge between the elevated notopodia differs among specimens. Larger specimens usually have a more pronounced dorsal ridge. The only other species in the genus with 3 pairs of branchiae are Anobothrus laubieri (Desbruyères, 1978) and Anobothrus flabelligerulus sp. nov. Anobothrus dayi sp. nov. differs from these species by the conical shape of the prostomium and the wide gap between the groups of branchiae. Further differences include the chaetae of segment II (paleae), which are much thinner than those of A. flabelligerulus sp. nov., and the notochaetae of segment III, which are absent in A. dayi sp. nov. and A. flabelligerulus sp. nov. but present in A. laubieri.	en	Imajima, Minoru, Reuscher, Michael G., Fiege, Dieter (2013): Ampharetidae (Annelida: Polychaeta) from Japan.

Visible tips of buccal tentacles without ventral groove, smooth. Three pairs of cirriform branchiae in fused segments II + III, arranged in transverse row without median gap (Fig. 6 A, B); branchial bases fused, leaving the segmental origin of branchiae indeterminable (Fig. 16 C). Chaetae of fused segments II + III originating from segment II, very long and thick golden paleae with mucronate tips (Fig. 6 C).

03C687A0FFF3FF8BFF35F9FFFC47A2A5.taxon	discussion	Remarks. The number of paleae ranges from about 24 to 27 per fascicle. The new species is similar to Anobothrus paleatus Hilbig, 2000, A. nataliae Jirkov, 2008, and A. wakatakamaruae Imajima, 2009. All four species have elevated notopodia with hirsute notochaetae, connected by a dorsal ridge in thoracic unciniger 9 (fourth-to-last). Other Anobothrus species have this modification in thoracic unciniger 8 (fifth-to-last). The four species also share number, morphology and arrangement of the paleae. A. flabelligerulus differs from these species by the presence of 3, rather than 4 pairs of branchiae. The only other species with 3 pairs of branchiae, A. dayi sp. nov. and A. laubieri, have elevated notopodia in thoracic unciniger 8, and much less developed chaetae in segment II. We have examined the holotype and three paratypes of A. nataliae and consider the species a junior synonym of A. paleatus. Jirkov (pers. comm.) shares our opinion. The examination revealed that A. nataliae has papillated, rather than smooth buccal tentacles. In addition to the circular band in thoracic unciniger 3, the development of a circular glandular band in thoracic unciniger 2 varies between absent, inconspicuous, and prominent. These two observations lead us to the conclusion that A. wakatakamaruae, which has been described with circular glandular bands in thoracic uncinigers 2 and 3 and papillose buccal tentacles, is also a junior synonym of A. paleatus. No papillae have been observed in the buccal tentacles of A. flabelligerulus. However, only the tips were visible in the holotype and one paratype.	en	Imajima, Minoru, Reuscher, Michael G., Fiege, Dieter (2013): Ampharetidae (Annelida: Polychaeta) from Japan.

03C687A0FFF1FF8CFF35FAC9FD09A476.taxon	discussion	Remarks. The diagnosis has been emended to account for the first Sosane species with elevated and modified notopodia in the second-to-last and fourth-to-last thoracic uncinigers, respectively. Furthermore, the position of the branchiae, and the number of intermediate segments are included. The synonymies of the genera listed above, suggested by Jirkov (2001, 2011), are accepted. The characteristic Sosane - like modification of a posterior thoracic unciniger in these genera is considered synapomorphic. Sosanopsis Hessle, 1917 differs from Sosane Malmgren, 1866 only by the absence of chaetae in segment II (“ paleae ”). This character is not considered valid for the distinction of genera (Jirkov 1994 a, 2001, 2008, 2011; Reuscher et al. 2009; Parapar et al. 2012). The monotypic genus Sosanella Hartman, 1965 was described with 13 thoracic uncinigers. Our examination of the holotype revealed that only 12 thoracic uncinigers are present. The species Sosanella apalea Hartman, 1965 is herein considered a junior synonym of Sosane wireni, Sosanella a junior synonym of Sosane. The holo- and paratype of Melinnata americana Hartman, 1965 are incomplete, missing the modified segment. The species, and the monotypic genus Melinnata Hartman, 1965, are therefore indeterminable. The possible synonymy of the genus with Sosane is doubtful.	en	Imajima, Minoru, Reuscher, Michael G., Fiege, Dieter (2013): Ampharetidae (Annelida: Polychaeta) from Japan.

Sosane brevibranchiata sp. nov. differs from the other species of Sosane sensu stricto, S. jirkovi, S. occidentalis, and S. sulcata, by the rudimentary 4 th pair of branchiae and the large gap between the groups of branchiae. The ventral tufts of cilia in the first 3 pairs of branchiae and their distinct annulation have also been observed in other species of the genus Sosane, i. e., Sosane uebelackerae sp. nov. (see below), and other genera, e. g., Anobothrus (see above). The ciliation is probably a juvenile character.	en	Imajima, Minoru, Reuscher, Michael G., Fiege, Dieter (2013): Ampharetidae (Annelida: Polychaeta) from Japan.

03C687A0FFF7FF8EFF35FBE6FBC7A4AD.taxon	discussion	Remarks. During the examination of holo- and paratypes of Sosane cinctus (Hartman, 1965) we found that the species has 4, rather than 3 pairs of branchiae. The number of branchiae is, even with methyl green staining, indeterminable in specimens where branchiae are broken off, e. g. in the holotype. Several paratype specimens, however, have a complete set of 4 pairs of branchiae. Numbers of thoracic chaetigers and uncinigers are 14 and 11, respectively, which is in contrast to the 13 thoracic chaetigers and 10 thoracic uncinigers given in the original description. In our single specimen all branchiae are broken off. We were not able to determine the number of branchiae. All other characters, however, agree with those observed in S. cinctus.	en	Imajima, Minoru, Reuscher, Michael G., Fiege, Dieter (2013): Ampharetidae (Annelida: Polychaeta) from Japan.

03C687A0FFEBFF93FF35F953FECCA370.taxon	discussion	Remarks. The tips of buccal tentacles are visible in one paratype. Besides the usual, smooth tentacles, some median ones are covered by papillae. Papillated tentacles have never been described in any of the Sosane species. The specimens from Japan do not differ morphologically from the Gulf of Mexico specimens described by Uebelacker (1984) as Genus A, which have since been referred to as Genus A sensu Uebelacker or Sosane sp. Uebelacker. The three smallest of the four examined specimens from the Gulf of Mexico have ventral tufts of cilia in their branchiae. This is the first species with the typical Sosane modification in the second-to-last thoracic unciniger. The only other species of the genus with only 3 pairs of branchiae, Sosane bathyalis and S. wahrbergi, have 9 thoracic uncinigers and the modified notopodia in the last thoracic unciniger. All other species with 12 thoracic uncinigers have 4 pairs of branchiae, 2 intermediate uncinigers, and the modified notopodia in the third-to-last thoracic unciniger.	en	Imajima, Minoru, Reuscher, Michael G., Fiege, Dieter (2013): Ampharetidae (Annelida: Polychaeta) from Japan.

03C687A0FFE9FF94FF35FA86FE38A191.taxon	discussion	Remarks. There are two different species, Sosane wireni (Hessle, 1917) (described as Sosanopsis wireni) and Sosane wireni Caullery, 1944. The synonymy of Sosane and Sosanopsis would leave S. wireni Caullery, 1944 as homonym of Hessle’s species. However, Caullery’s species description of S. wireni and S. fauveli Caullery, 1944 seem to be based on a misconception of the genus Sosane since both of Caullery’s species do not have the characteristically modified segment. We think that Caullery’s species may belong to Lysippe. A re-examination of Caullery’s material was not possible because collections were being moved between the natural history museums of Amsterdam and Leiden during the time of this study.	en	Imajima, Minoru, Reuscher, Michael G., Fiege, Dieter (2013): Ampharetidae (Annelida: Polychaeta) from Japan.

03C687A0FFEFFF95FF35FF4CFEBFA381.taxon	discussion	Remarks. Tanseimaruana gen. nov. shares the number of thoracic chaetigers, absence of intermediate uncinigers, number of branchiae, and presence of enlarged chaetae (paleae) in segment II with Amphicteis and a number of other genera. However, because of a number of differences, we think that the description of Tanseimaruana gen. nov. for the two species Tanseimaruana vestis (Hartman, 1965) comb. nov., described as Amphicteis vestis, and T. boninensis sp. nov. is warranted. Tanseimaruana gen. nov. lacks prostomial glandular ridges, possesses 4 foliose lobes that emerge from a dermal fold in the first abdominal unciniger, and its uncini have several rows of teeth, rather than a single row. Jugamphicteis Fauchald & Hancock, 1981, another genus that is related to Amphicteis, also has a dorsal lobe structure in the first abdominal unciniger. The dorsal modification of Jugamphicteis is a very high “ valve-like ” (Fauchald & Hancock 1981) dermal fold with papillated convex margin and a median notch. Despite the same location of the modification, we share the opinion of Fauchald & Hancock (1981) and Holthe (2000), who discussed the status of Tanseimaruana vestis (as Amphicteis vestis), that the modification of Jugamphicteis is different. Therefore, they are not considered homologous. Furthermore, Jugamphicteis differs from Tanseimaruana gen. nov. by the presence of prostomial glandular ridges. The modifications in Tanseimaruana vestis comb. nov., in the four species of Jugamphicteis, and in the monotypic genus Ymerana Holthe, 1986 b have been defined as modified notopodial structures by their describers. This terminology was reiterated by subsequent authors (Jirkov 2008, 2011; Reuscher et al. 2009; Parapar et al. 2011). However, a notopodial origin of the dermal fold or lobes seems unlikely. The lobes do not resemble notopodia. They rather seem to be dermal protrusions from a transverse dermal fold across the dorsum. The dermal folds with its accessory structures are likely to be apomorphic structures that might have evolved to help create a current through the mucus-sediment tube (see also Parapar et al. 2011). A notopodial origin seems also unlikely in the light of the phylogeny of the genus. Tanseimaruana gen. nov. and, even more so, Jugamphicteis seem to be genera that are related to Amphicteis. All three genera have 17 pairs of notopodia (paleae of segment II not included). If the modification of Tanseimaruana gen. nov. and Jugamphicteis was of notopodial origin, Amphicteis, the potential ancestral genus, would be expected to have an additional 18 th pair of notopodia from which the lobes have been derived. Additionally, the neuropodia of the modified segment are not tori but pinnules, which is a strong indication that the modified segment belongs to the abdomen, rather than to the thorax.	en	Imajima, Minoru, Reuscher, Michael G., Fiege, Dieter (2013): Ampharetidae (Annelida: Polychaeta) from Japan.

03C687A0FFEFFF97FF35F9F2FC48A7E6.taxon	discussion	Remarks. Tanseimaruana boninensis sp. nov. resembles the genotype, T. vestis (Hartman, 1965), in the shape of the prostomium, the arrangement of branchiae, and the presence of 4 foliose lobes in the first abdominal chaetiger. T. boninensis sp. nov. can be distinguished from T. vestis by the presence of ventral papillae in the notopodia, conical dorsal cirri in the tori, and dorsal papillae in the pinnules. The type specimen broke between thorax and abdomen during a shipment. Drawings were prepared prior to the shipment when the specimen was in one piece (Fig. 13).	en	Imajima, Minoru, Reuscher, Michael G., Fiege, Dieter (2013): Ampharetidae (Annelida: Polychaeta) from Japan.

03C687A0FFEDFF98FF35FC5EFA3AA191.taxon	discussion	Remarks. The two paratypes are complete. They have 20 and 21 abdominal uncinigers, respectively. The pygidium bears a pair of blunt ventral lobes (Fig. 14 J). Zatsepinia jirkovi sp. nov. is only the second species of the genus. It differs from Zatsepinia rittichae by having 3, rather than 2 pairs of branchiae. The new species has 20 – 21 abdominal uncinigers, Z. rittichae has only 13 – 15. Furthermore, the pygidium bears two blunt lobes, whereas Z. rittichae has a pygidium that bears a ring of papillae around the anus. The thoracic uncini have 3 teeth in single row over paired teeth, whereas Z. rittichae has thoracic uncini with two median teeth in a single row over 4 teeth in 2 lateral rows. Despite the differences that require an emendation of the generic diagnosis, we refrained from describing a new genus. The shape of the prostomium, the absence of chaetae in segment III, the type and position of the elevated notopodia connected by a dorsal ridge, and the unusually high number of 4 intermediate uncinigers are unique characters among all ampharetid genera, shared by Z. rittichae and Z. jirkovi sp. nov.	en	Imajima, Minoru, Reuscher, Michael G., Fiege, Dieter (2013): Ampharetidae (Annelida: Polychaeta) from Japan.

03C687A0FFE3FF9BFF35FF4CFC8CA43E.taxon	discussion	Remarks. Three of the examined specimens collected in November 2007 are filled with eggs. The abdominal unciniger count of 15 is slightly higher than in the holotype (13). The tentacles, of which only the tips are visible in the holotype, seem to be smooth, in contrast to Jirkov’s description as “ pinnate (?) ”, and the uncini are in agreement with our specimens. We consider the difference in the number of abdominal uncinigers an intraspecific variation.	en	Imajima, Minoru, Reuscher, Michael G., Fiege, Dieter (2013): Ampharetidae (Annelida: Polychaeta) from Japan.
