Boroecia antipoda (Müller, 1906) (Figures 4–6) Synonymy: 1906 Conchoecia antipoda Müller: 110, Pl xxvi 5–16 (‘ mollis group’). 1912 Conchoecia antipoda —Müller: 97. 1920 Conchoecia borealis antipoda —Skogsberg: 718–719, Fig. 137 1921 Conchoecia antipoda —Barney: 182. 1967 Conchoecia antipoda —Hillman: 199–200. 1969 Conchoecia antipoda —Hillman: 189 1972 Boroecia antipoda —Rudjakov: 52–62 non 1973 Boroecia antipoda —Poulsen: 170–171, Fig. 87 A–G. 1974 Conchoecia antipoda —Deevey: 375, Fig. 87 A–G. 1976 Conchoecia antipoda —Deevey: 43–46. 1978 Conchoecia antipoda —Deevey: 65, Fig 18. 1981 Conchoecia antipoda —Angel: 557, Fig. 194–21. 1985 Boroecia antipoda —Hopkins: 202. 1992 Boroecia antipoda —Benassi et al.: 247. 1992 Boroecia antipoda— Kock: 54–59, Fig. 15. 1999 Boroecia antipoda —Angel: Fig. 9.30. 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(2003) plotted its geographical distribution based on all published reports, supplemented by a considerable amount of unpublished data from Discovery Investigations and showed that this species is almost entirely restricted to latitudes south of 40°S, i.e. it is endemic to the Southern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.
