This extensive synonymy indicates that this species has been regularly recorded in the Southern Ocean, where it is one of the dominant species in the halocyprid assemblages at mesopelagic depths (e.g. Błachowiak-Samołyk & Osowiecki 2002). Müller (1906) reported it at 12 of the Tiefsee stations. However, the record from Tiefsee Station 54 (in the Gulf of Guinea) must be now considered as highly dubious, because subsequent extensive sampling in this region (e.g. Poulsen 1969, Angel et al. 2007, Angel 2010) has failed to confirm its presence (or that of any other Boroecia species). Błachowiak-Samołyk & Angel (2003) plotted its geographical distribution based on all published reports, supplemented by a considerable amount of unpublished data from Discovery Investigations and showed that this species is almost entirely restricted to latitudes south of 40°S, i.e. it is endemic to the Southern Ocean. When we examined the specimens identified as B. antipoda from the Dana Expedition (Poulsen 1973) sampled at low latitudes in the Pacific Ocean, all but one (the female from Dana Station 3642 (46°43’S; 176°09’E)), were found to be a different and novel species, which is described below as B. danae n. sp.
