Bimeria franciscana View in CoL .— Joyce, 1961: 36, pl. 5, figs 3, 4 [not Bimeria franciscana Torrey, 1902 View in CoL ].

Type locality. USA: Florida, Dry Tortugas, shallow water ( Allman 1877: 9) .

Material examined. Fort Myers Beach, stranded intertidally on detached octocoral, 16 February 2013, one colony, 4 mm high, without gonophores, coll. D. Calder, ROMIZ B4330.—Sanibel Island, beach at Lighthouse Point, on a detached and stranded colony of Thyroscyphus , 13 December 2017, one colony, 6 mm high, without gonophores, coll. D. Calder, ROMIZ B4331.

Remarks. Bimeria humilis Allman, 1877 from the southwest coast of Florida ( Allman 1877), and other locations in the warm western Atlantic ( Vervoort 1968), has frequently been considered a junior synonym of B. vestita Wright, 1859 from Scotland and elsewhere in northwest Europe ( Schuchert 2007). This hypothesis needs confirmation given the very different environmental conditions extant at these locations. Allman’s (1877) species is provisionally upheld as valid here.

Hydroids misidentified as Bimeria franciscana by Joyce (1961) from Seahorse Key, on the Gulf Coast of Florida, were based on specimens of Bimeria humilis Allman, 1877 .

Reported distribution. Gulf coast of Florida. Dry Tortugas, shallow water ( Allman 1877: 9).—Seahorse Key ( Joyce 1961: 36, misidentified as Bimeria franciscana ).
