non Laetmogone wyvillethomsoni Théel, 1879 — Hérouard 1902: 31–32, pl. 4, figs. 10–16 [misidentification]; Mortensen 1927a: 361 [based on Hérouard 1902]; Grieg 1932: 5, 46 [based on Hérouard 1902].
Type locality: off Chile, Southern Pacific Ocean.
See: Hansen (1975: 54–57, fig. 20); O’Loughlin (2002: 321).
Occurrence: Southern Ocean and Antarctica (Hansen 1975).
Depth: 245– 4,410 m (O’Loughlin 2002).
Habitat: soft substrates (Hansen 1975).
Remarks: Hansen (1975) believed that all historical reports of Laetmogone wyvillethomsoni from the Atlantic were misidentifications of closely similar species such as L. violacea. However, on re-examination of the specimens identified by Hérouard (1902) from the Azores, Hansen suggested that these animals belonged to a yet unnamed new species (see also remarks under L. violacea).
