Current status. Valid.

Remarks. The hydroid described as Antennella curvitheca  by Fraser (1937b) was collected off the northeast coast of Puerto Rico during the Johnson-Smithsonian Deep-Sea Expedition. Material designated as the holotype by Fraser ( USNMAbout USNM 43291), currently listed as a syntype in the NMNHAbout NMNH online database, is taken to be a single colony after its examination here. Paratype material exists at the RBCMAbout RBCM ( BCPMAbout BCPM 976-00816-001; BCPMAbout BCPM 976-00816-002). No gonophores were present in Fraser’s material, but the species is distinctive in the curvature of the adcauline wall of the hydrotheca ( Schuchert 1997). Gonothecae have subsequently been described by Van Gemerden-Hoogeveen (1965) and Schuchert (1997).

Antennella curvitheca  is considered valid ( Schuchert 1997; Cairns et al. 2002; WoRMS). Outside several locations in the Caribbean region ( Galea 2010), the species is now known to range from Plantagenet (=Argus) Bank, near Bermuda ( Calder 2000), to waters of the continental shelf off Brazil ( Grohmann et al. 2003).
