Genus Bispira Krøyer, 1856

Remarks. A partial revision of Bispira was provided by Knight-Jones & Perkins (1998). A cladistic analysis was undertaken by Fitzhugh (1989), which found Bispira as monophyletic with the inclusion of the sister taxa Branchiomma Kölliker, 1858 , and Pseudobranchiomma Jones, 1962 , supported by a number of synapomorphies: presence of interramal eyespots; inferior thoracic notochaetal fascicles in bundles with longitudinal chaetal rows, and abdominal neuropodial tori in the form of conical lobes. On the contrary, the hypothesis provided by Capa (2008), found Bispira as paraphyletic without the inclusion of Pseudobranchiomma and Branchiomma , but the high homoplasy and the low jacknife support for the clade suggest that these results are preliminary. Currently Bispira is composed of 22 species ( Capa et al. 2014). In South America , only one species of Bispira is currently known, B. klautae Costa-Paiva & Paiva, 2007 , from Rocas Atoll ( Brazil).
