3. Pentactella Verrill, 1876 .

Many Discovery Expedition lots have been identified as species of Pentactella Verrill, 1876 . Based on morphological characters and distribution consideration, and with the support of some genetic data, O’Loughlin et al. (2014) reassigned numbers of species of Pseudocnus Panning, 1949 to a new genus Laevocnus O’Loughlin (in O’Loughlin et al. 2014). Immediately after publication the authors recognized that the type species for the new genus Laevocnus was the type species for the monotypic Pentactella Verrill, 1876 . Laevocnus is an objective junior synonym of Pentactella . A detailed systematic history of genus Pentactella , and the assigned species, is provided by O’Loughlin et al. (2015).
