Type locality: off Cape Verde.
See: A.M. Clark & Downey (1992); Benavides-Serrato et al. (2011: 127).
Occurrence: North Atlantic, from the Denmark Strait (SW of Iceland; A.M. Clark & Downey 1992), south of the Rockall Trough (Harvey et al. 1988) to NW Africa, including the Azores, Madeira and Cape Verde (Koehler 1909); also reported for the Gulf of Mexico and the Caribbean (A.M. Clark & Downey 1992).
Depth: 730– 2,970 m (A.M. Clark & Downey 1992); AZO: 1,095 –1,919 m (Koehler 1909).
Habitat: soft sediments (Koehler 1909).
Larval stage: lecithotrophic (A.M. Clark & Downey 1992).
Remarks: Perrier (1896a) reported Psilaster andromeda based on material collected by Hirondelle in the Azores. Later, Koehler (1909) re-examined the material and concluded that Perrier confused P. andromeda with Persephonaster patagiatus (= Psilasteropsis patagiatus), and reassigned the specimens to the latter species (see remarks under P. andromeda andromeda).
