Metambasia faeroensis Stephensen, 1923: 76 , figs 15, 16.―J.L. Barnard, 1958: 95 (list).― Lincoln, 1979: 40.― Palerud & Vader, 1991: 38.― Barnard & Karaman, 1991: 503.— Sainte-Marie, 1991: 217, appendix 1.

Types. Syntypes, 1 male and 1 female, both 6 mm, ZMUC CRU-6388 ; many specimens, ZMUC CRU-6389 , from Thor Stn 78. 8 specimens from Thor stn 99, 7 females (all with oostegites?) 5–6 mm, 1 adult male, about 8 mm, ZMUC CRU-6390 .

Type locality. South-west of the Faeroe Islands north-east Atlantic Ocean at 835 m depth (61°07'N 9°30'W), and 900 m depth (61°05'N 9°35'W) .

Depth range. 835–900 m ( Stephensen 1923).

Remarks. This species appears to have only been collected once, at two separate stations, with a limited distribution near the Faeroe Islands ( Stephensen 1923). It is extremely distinctive with a parachelate gnathopod 1 and vestigial gnathopod 1 coxa. In the original description of the species Stephensen (1923) specified that his description and illustrations were based on a 6 mm ovigerous female and an 8 mm adult male from the syntypes series.
