Erroneous— Psychroplanes obsoleta (Hérouard, 1899)

Reports for the Azores:

Peniagone (Kolga) obsoleta (Hérouard, 1899) — Perrier 1902: 276.

Type locality: between the Azores and the European continent (39°50’N, 17°57’45”W) .

See: Hérouard (1899: 170, fig. 1; 1902: 41–42, pl. 6, figs. 11–15, pl. 8, figs. 16–18, as Kolga obsoleta); Hansen (1975: 134–135, fig. 56).

Occurrence: known from the Mid-Atlantic near the equator and the deep waters between the Azores and the European shores (Hansen 1975); reported elsewhere in the east of the Japanese Trench (Pacific; Gebruk et al. 2014).

Depth: 4,275–6,096 m (Gebruk et al. 2014).

Habitat: soft sediments (Hérouard 1923).

Remarks: Perrier (1902) mentioned Psychroplanes obsoleta among the species reported by Hérouard from the Azores. However, Hérouard (1902) clearly states that the specimens came from waters between the Azores and the European mainland (Princesse Alice, sta 753: 39°50’00”N, 17°57’45”W, 4,360 m). It is possible that P. obsoleta may occur in the abyssal waters of the Azores, considering the known geographical and bathymetric distribution of this species, but at present no records from the archipelago exist.
