Description:
<jats:p><jats:italic>Chauvinelia</jats:italic> contains two abyssal species, <jats:italic>C. biscayensis</jats:italic>, and <jats:italic>C. arctica</jats:italic>. Because of the lack of some relevant details in the original descriptions, they are redescribed, the generic diagnosis is emended, and a key to separate them is included. <jats:italic>Flabelliseta incrusta</jats:italic> and <jats:italic>Helmetophorus rankini</jats:italic>, the type and only species for these genera are redescribed; they lack annulated or multi-articulated capillaries, their chaetae have a detachable cortex carrying successive rows of tiny spines, and they share several features with <jats:italic>Chauvinelia</jats:italic>. Therefore <jats:italic>Flabelliseta</jats:italic>, and <jats:italic>Helmetophorus</jats:italic>, currently regarded as members of Flabelligeridae de Saint-Joseph, 1894, are transferred to the Acrocirridae Banse, 1969. Consequently the family diagnosis is emended to include simple capillary neurochaetae, and a key for all acrocirrid genera is also included.</jats:p>
