Exploring Deep-Sea Biodiversity in the Porcupine Bank (NE Atlantic) through Fish Integrative Taxonomy
This study combined morphological and molecular approaches to the species assignment of several rare or poorly known deep-water fishes caught between 549 and 1371 m depth during a Spanish bottom trawl survey in the Porcupine Bank, west of Ireland. The following fish species were identified: <i>...

| description | This study combined morphological and molecular approaches to the species assignment of several rare or poorly known deep-water fishes caught between 549 and 1371 m depth during a Spanish bottom trawl survey in the Porcupine Bank, west of Ireland. The following fish species were identified: <i>Nessorhamphus ingolfianus</i> (Schmidt, 1912), <i>Borostomias antarcticus</i> (Lönnberg 1905), <i>Scopelosaurus lepidus</i> (Krefft and Maul 1955), <i>Bathypterois dubius</i> Vaillant, 1888, <i>Evermannella balbo</i> (Risso, 1820), <i>Antimora rostrata</i> (Günther, 1878), <i>Melanonus zugmayeri</i> Norman, 1930, <i>Lyconus brachycolus</i> Holt and Byrne, 1906; <i>Paraliparis hystrix</i> Merrett, 1983, <i>Neocyttus helgae</i> (Holt and Byrne, 1908); <i>Platyberyx opalescens</i> Zugmayer, 1911; <i>Howella atlantica</i> Post and Quéro, 1991, <i>Lycodes terraenovae</i> Collett, 1896 and <i>Pseudoscopelus altipinnis</i> Parr, 1933. The presence of <i>L. brachycolus</i>, <i>P. opalescens</i> and <i>P. altipinnis</i> is reported for the first time in the Bank. The DNA barcoding results were largely consistent with morphological identification in 10 species but four did not fit the current taxonomy, indicating cases of potential cryptic speciation, misidentification, synonymy or recent diversification. Among them, the results strongly suggest that <i>P. garmani</i> and <i>P. hystrix</i> are conspecific, making <i>P. hystrix</i> a junior synonym of <i>P. garmani</i>. |
