Remarks. This hydroid has commonly been known as Dynamena quadridentata ( Ellis & Solander, 1786) (synonymy in Vervoort & Watson 2003). However, molecular studies by Moura et al. (2011) indicate that the nominal genus Dynamena Lamouroux, 1812 is polyphyletic, and that D. quadridentata is genetically distant from D. pumila ( Linnaeus, 1758) , its type species. Pasya Stechow, 1922 (type species: Sertularia quadridentata Ellis & Solander, 1786 ), generally regarded as a synonym of Dynamena , is resurrected here for the species. The specific name quadridentata has also been combined in the past with Pasythea Lamouroux, 1812 , but that nominal genus is now restricted to Bryozoa (type species: Cellaria tulipifera Ellis & Solander, 1786 ). Additional discussion of nomenclature relevant to these names has been given earlier (Calder 1991: 89).

Pasya quadridentata , common in the Caribbean Sea region ( Vervoort 1968; Calder & Kirkendale 2005, as Dynamena quadridentata ), ranges northwards to the Carolinas along the east coast of the United States ( Cain 1972; Calder 1983, as D. quadridentata ). The species is transported to even higher latitudes in the Gulf Stream on floating Sargassum ( Fraser 1912b; Burkenroad, in Parr 1939, as Pasythea quadridentata ), including New England ( Hargitt 1908, as Pasythea nodosa ).

Reported distribution. Atlantic coast of Florida. Biscayne Bay ( Jones 2002, as Dynamena quadridentata ).

Western Atlantic. Woods Hole region, Massachusetts ( Hargitt 1908, as Pasythea nodosa ) to Brazil (Oliveira et al. submitted, as D. quadridentata ), including Bermuda ( Calder, 1991a, as D. quadridentata ), the Gulf of Mexico ( Calder & Cairns 2009, as D. quadridentata ), and the Caribbean Sea ( Calder & Kirkendale 2005, as D. quadridentata ).

Elsewhere. Circumglobal in temperate and tropical waters ( Vervoort 1968; Vervoort & Watson 2003).
