Amphiophiura convexa
Description
Amphiophiura convexa (Lyman, 1878) Reports for the Azores:
Ophioglypha convexa (Lyman, 1878) — $ Koehler 1909: 149–150, pl. 25, figs. 1–2;
Amphiophiura convexa (Lyman, 1878) — Mortensen 1927a: 231; $ Cherbonnier & Sibuet 1972: 408; Martynov & Litvinova 2008: 81, fig. 2D;
Ophiura convexa (Lyman, 1878) — Grieg 1932: 32;
Amphiophiura bullata convexa (Lyman, 1878) — Paterson 1985: 132–133, fig. 51; García-Diez et al. 2005: 49; Smirnov et al. 2014: 201.
Type locality: E of Japan, Pacific.
See: Lyman (1878: 84, pl. 3, figs. 83–84, as Ophioglypha convexa); Paterson (1985).
Occurrence: cosmopolitan, in the Atlantic, Pacific and Indian Oceans; in the west Atlantic from Labrador basin to off New England (Paterson 1985) and in the East Atlantic, from Reykjanes Ridge south to the Bay of Biscay (Martynov & Litvinova 2008), Azores, Canaries (Koehler 1909) and?Madeira (Jesus & Abreu 1998); also reported from Vema Fracture zone, off Central African coast (24°02’S 14°41’W; Lyman 1882) and Demerara Abyssal Plain, off northern South America (Paterson 1985).
Depth: 1,950 –6,810 m (Smirnov et al. 2014); AZO: 3,665 –4,261 m (Koehler 1909, Cherbonnier & Sibuet 1972).
Habitat: soft bottoms (ooze; Koehler 1909).
Remarks: Koehler (1909, 1914a) remarked on the variability present in Amphiophiura convexa (= Ophioglypha convexa), which in certain aspects of its morphology resembles A. bullata (Thomson, 1877). Paterson (1985) based on the variability of the dorsal plating of the disc, assumed A. convexa to be a subspecies of A. bullata. Martynov & Litvinova (2008) disagreed and maintained the specific status, a view followed herein.
Jesus & Abreu (1998) reported an ‘ Amphiophiura cf. bullata convexa ’ from Madeira shallow waters, between 20 and 100 m. In the North Atlantic, the genus Amphiophiura includes strictly deep-water species that tend to live well below 1,000 m (Paterson 1985; Smirnov 2014). In light of this, we doubt that the material reported by Jesus & Abreu (1998) belongs to A. convexa or even the genus Amphiophiura.
