Type locality. Indonesia: “Baie d’Amboine” (Pictet 1893).
Voucher material. Beach north of Jupiter Inlet, 26°56’45”N, 80°04’16”W, washed ashore on a tarball, 20.ii.1991, collected manually, one colony, up to 6 mm high, without gonophores, coll. D.R. Calder, ROMIZ B1109.— Sebastian Inlet, 27°51’43”N, 80°26’47”W, washed ashore on Sargassum, 19.ii.1991, collected manually, one colony, up to 8 mm high, without gonophores, coll. D.R. Calder, ROMIZ B3971.— Fort Pierce, Fort Pierce Inlet State Park, 27°28’29.5”N, 80°17’25.8”W, on stranded Sargassum fluitans, 14.vii.2012, 28° C, 35‰, collected manually, two colonies, up to 6 mm high, without gonophores, coll.

Remarks. Plumularia strictocarpa Pictet, 1893 resembles P. setacea (Linnaeus, 1758), but its gonothecae are barrel- to cocoon-shaped with spiral annulations instead of being fusiform with smooth walls. Its colonies also tend to be much smaller. It is one of the more abundant species on pelagic Sargassum in the western North Atlantic (Calder, 1995, 1997).
Reported distribution. Atlantic coast of Florida. Biscayne Bay (Jones 2002).
Western Atlantic. From the Gulf Stream off Nova Scotia (Fraser 1918, on Sargassum, as Plumularia setaceoides Bale, 1882) to Brazil (Oliveira et al. submitted), including Bermuda (Calder 1991a), the Gulf of Mexico (Calder & Cairns 2009), and the Caribbean Sea (Calder & Kirkendale 2005).
Elsewhere. Circumglobal, tropical and subtropical waters (Kirkendale & Calder 2003).
