Branchiomma
No full textBranchiomma species The Branchiomma species in WoRMS (2015) are not completely updated, in fact, its list reports 34 species but some are not valid names. After our review, we refine the list of Branchiomma to 29 confirmed species (Table 2), as some belong to other genera: B. claparedei is Megalomma claparedei Gravier, 1906 and a Lessepsian migrant species; B. kumara, B. picta and B. serratibranchis are Pseudobranchiomma according to Knight-Jones (1994); B. sanjuanense is Sabellastarte magnifica (Shaw, 1800) according to Hartman (1956: pg. 299) and Jones (1962; pg. 201); and B. violacea is Hypsicomus phaeotenia (Schmarda, 1861) according to Hartman (1965).Published as part of Keppel, Erica, Tovar, Maria Ana & Ruiz, Gregory, 2015, First record and establishment of Branchiomma coheni (Polychaeta: Sabellidae) in the Atlantic Ocean and review of non – indigenous species of the genus, pp. 499-518 in Zootaxa 4058 (4) on page 505, DOI: 10.11646/zootaxa.4058.4.3, http://zenodo.org/record/24428
Branchiomma coheni Tovar-Hernandez and Knight-Jones 2006
No full text<i>Branchiomma coheni</i> Tovar-Hernández and Knight-Jones, 2006 <p> <i>Branchiomma coheni</i> was described from the Pacific coast of Panama in 2006 (Tovar-Hernández & Knight-Jones, 2006) and is first recorded in the Atlantic Ocean (Florida) in this study. In the Gulf of California, <i>B. coheni</i> is found in marinas and ports (docks, buoys, ropes, all hull fouling) but even in aquaculture facilities (oyster and shrimp cultures) where it is found in relatively low abundance, reportedly in the ratio of 1:100 with <i>B. bairdi</i> (Tovar- Hernández, unpublished data). Nevertheless, this species could increase in abundance depending on abiotic and biotic factors of the environment, therefore it is important to maintain monitoring although it is not presently considered a threat to marine ecosystem health.</p>Published as part of <i>Keppel, Erica, Tovar, Maria Ana & Ruiz, Gregory, 2015, First record and establishment of Branchiomma coheni (Polychaeta: Sabellidae) in the Atlantic Ocean and review of non – indigenous species of the genus, pp. 499-518 in Zootaxa 4058 (4)</i> on page 508, DOI: 10.11646/zootaxa.4058.4.3, <a href="http://zenodo.org/record/244288">http://zenodo.org/record/244288</a>
Branchiomma nigromaculatum Baird 1865
No full textBranchiomma nigromaculatum (Baird, 1865) This species was first described from the Caribbean Sea, with many records in the Atlantic Ocean. The Australian Check list reports this species for the Pacific Sea (ABRS 2009) but neither Çinar (2013) nor Capa (2013) cited this species or commented on its status. Previous records of B. nigromaculatum from Australia were found by Hartmann-Schröder (1986; 1989; 1991), Hutchings & Rainer (1979), and Hutchings & Murray (1994). The last references reported B. nigromaculatum as widespread in most estuaries of New South Wales throughout the year, but figures or descriptions were not provided. Capa (pers. comm.) re-examined specimens reported from Australia but identification as B. nigromaculatum was not corroborated because specimens were small and morphological traits were not completely developed. Thus, presence of B. nigromaculatum in Australia is still in doubt. Day (1967) reported B. nigromaculatum from South Africa, but Tovar-Hernández & Knight-Jones (2006) suggested that it belongs to B. corollifera Ehlers, 1913. The Hawaiian record of B. nigromaculatum by Bailey- Brock (1987) seems to be B. cingulatum (B. japonicum), but more studies are needed to clarify its status.Published as part of Keppel, Erica, Tovar, Maria Ana & Ruiz, Gregory, 2015, First record and establishment of Branchiomma coheni (Polychaeta: Sabellidae) in the Atlantic Ocean and review of non – indigenous species of the genus, pp. 499-518 in Zootaxa 4058 (4) on page 510, DOI: 10.11646/zootaxa.4058.4.3, http://zenodo.org/record/24428
Branchiomma curtum Ehlers 1901
No full textBranchiomma curtum (Ehlers, 1901) This species was described from Juan Fernández Island (Chile) in 1901, and it was recorded in New Zealand, Cape Verde Islands and the Mexican Caribbean (Tovar-Hernández & Knight-Jones, 2006). In the latter area, it was reported as abundant living in gregarious clumps among algae and was thought to be introduced by ballast water from ships (Tovar-Hernández & Knight-Jones 2006). There are no new records of B. curtum elsewhere; however, the record by Tovar-Hernández & Knight-Jones (2006) from Caribbean may be erroneous, requiring further sampling, because both syntypes of B. curtum and Caribbean specimens were juveniles produced by fission with a low number of thoracic segments (4–6). This is a common reproductive phenomena in species of Branchiomma (Tovar-Hernández & Dean 2014). Materials examined and compared by Tovar-Hernández & Knight-Jones (2006) do not show significant morphological differences with Ehlers syntypes because juveniles of different species can look all similar. Shape and size of stylodes in juveniles of many species of Branchiomma change in adult stages. Additionally, the original description and drawings by Ehlers (1901) emphasized important differences among the nominal species B. curtum and specimens reported in from the Mexican Caribbean. The thoracic uncini has one row of teeth, covering 1 / 4 of the main fang length in B. curtum (Ehlers 1901: plate 25, Fig. 13) versus three rows covering 1 / 2 of the main fang length in Caribbean material. Thus, the status of B. curtum as NIS in the Mexican Caribbean, New Zealand and Cape Verde demands a further morphological study using adult forms as well as molecular markers at juvenileadult stages.Published as part of Keppel, Erica, Tovar, Maria Ana & Ruiz, Gregory, 2015, First record and establishment of Branchiomma coheni (Polychaeta: Sabellidae) in the Atlantic Ocean and review of non – indigenous species of the genus, pp. 499-518 in Zootaxa 4058 (4) on page 508, DOI: 10.11646/zootaxa.4058.4.3, http://zenodo.org/record/24428
Branchiomma japonicum McIntosh 1885
No full textBranchiomma japonicum (McIntosh, 1885) This species was described from Kobé, Japan in 1885. Carlton & Eldredge (2009) regarded B. japonicum as introduced in Hawaii, given its largely harbor and fouling habitat in the Islands and the highly disjunct distribution between Japan and Hawaii. However, confusion arises when trying to track records of B. japonicum, a species name which is under a subjective synonym (B. cingulatum (Grube, 1870). In addition, one Branchiomma species originally described from Honolulu (B. havaicum Kinberg, 1867) was synonymized with B. cingulatum by Hartman (1948). Augener (1914) and Imajima & Hartman (1964) suggested that B. japonicum is synonym of B. cingulatum, a species described originally from the Fiji islands. However, Augener (1914) and Imajima & Hartman (1964) did not provide any evidence or comments about this consideration and stylodes were not described. Knight-Jones (1994) introduced both names (B. cingulatum and B. japonicum) as separate species while trying to form groups based on artificial categories, but any indication about the status of both species was not provided. She was reported to be in the process of redescribing B. cingulatum, but unfortunately, she died in 2009 without concluding her revision. Carlton & Eldredge (2009) included under the name B. japonicum previous records from Hawaii (Branchiomma nigromaculata of Bailey-Brock & Hartman (1987), Sabella havaica and Branchiomma cingulata of Hartman (1966) and many others studies). However, these attributions were based on a personal communication that Phyllis Knight-Jones had with Carlton & Eldredge in 2000, but not on the examination of specimens. Branchiomma cingulatum has uncini with two rows of teeth above the crest (Fitzhugh 2002: Fig. 2 B) and stylodes are digitiform, proximal stylodes with length same as radial width and more distal stylodes up to two times longer than radial width (Grube 1870: plate 14, Fig. 6 a–c; Fitzhugh 2002: Fig. 2 A). Although in B. japonica the uncini present only one clear tooth above crest and apparently a second short tooth (McIntosh 1885: plate 30 A, Fig. 24), stylodes are similar to those described for B. cingulatum (McIntosh 1885: plate 39 A, Fig. 5). Thus, the synonymy of these species remains tentative until a revision based on type materials can further clarify the status of species involved. If synonyms are confirmed among these three species, B. cingulatum will be the valid name according to Priority Principle of ICZN, having implications about its status as NIS in Hawaii or in other worldwide localities.Published as part of Keppel, Erica, Tovar, Maria Ana & Ruiz, Gregory, 2015, First record and establishment of Branchiomma coheni (Polychaeta: Sabellidae) in the Atlantic Ocean and review of non – indigenous species of the genus, pp. 499-518 in Zootaxa 4058 (4) on page 509, DOI: 10.11646/zootaxa.4058.4.3, http://zenodo.org/record/24428
Branchiomma luctuosum Grube 1870
No full textBranchiomma luctuosum (Grube, 1870) Branchiomma luctuosum was described from the Red Sea and reported as introduced for the first time in the Lucrino Lake (Naples, Tyrrhenian Sea, Italy) by Bianchi (1983). Since this first finding, many records of this species have been reported in the western and central Mediterranean basins (Sordino & Gambi 1992; Licciano et al. 2002; Mastrototaro et al. 2004; El Haddad et al. 2008; Licciano & Giangrande 2008; Giangrande et al. 2012), as well as in the eastern Mediterranean (Knight-Jones et al. 1991, Arvanitidis 2000; Simboura & Nicolaidou 2001; Çinar 2005; Çinar et al. 2006). It was included in the 100 ‘Worst Invasives alien marine species in the Mediterranean’ (Streftaris & Zenetos 2006). Moreover, this species was reported colonizing the Brazilian coast (Nogueira et al. 2006; Costa-Paiva et al. 2007). In the Red Sea, this species has been found mainly in the more sheltered areas of coral reefs (Grube 1870). In the Aegean Sea it has been found associated with sponges (Arvanitidis 2000), while its presence in Italian waters has mostly been recorded in lagoon environments (Sordino & Gambi 1992; Knight-Jones et al. 1991) or sheltered marine areas (Sordino & Gambi 1992; Licciano et al. 2002; Matarrese et al. 2004). In Valencia Port, El Haddad et al. (2008) found specimens of B. luctuosum mostly on rocky substrates, grouped in small aggregates of specimens or more rarely isolated. Specimens were present in practically all orientations of the substrate, but especially on the vertical surfaces of the docks where densities reached 320–370 ind./m 2. In Lake Faro, it was found in a maximum density of 19 ind./m 2 (Giangrande et al. 2012). In Brasil, it was found on rocky shores where it was the dominant sabellid sharing the space with B. patriota Nogueira, Rossi & López, 2006 and Parasabella microphtalma (Nogueira et al. 2006).Published as part of Keppel, Erica, Tovar, Maria Ana & Ruiz, Gregory, 2015, First record and establishment of Branchiomma coheni (Polychaeta: Sabellidae) in the Atlantic Ocean and review of non – indigenous species of the genus, pp. 499-518 in Zootaxa 4058 (4) on page 510, DOI: 10.11646/zootaxa.4058.4.3, http://zenodo.org/record/24428
