Bruunosa bruuni .― Barnard & Karaman, 1987: 864.― Barnard & Karaman, 1991: 472.

Types. Lectotype by present designation, 1 female, about 7 mm ( ZMUC CRU-5926 ).

Type locality. Kermadec Trench, South Pacific Ocean, 6660–6770 m depth.

Habitat. Sand, clay and stones.

Depth range. 6660–6770 m ( Dahl 1959).

Remarks. Dahl (1959) did not explicitly designate a holotype or any syntypes in his original description of the species, but refers to one female and one juvenile. In accordance with the International Code of Zoological Nomenclature ( ICZN 1999: Art. 72.1.1) this material collectively constitutes syntypes. The juvenile specimen is now apparently lost and four slides of the female are all that remain of the material. This is re-illustrated by us ( Fig. 1 ), and designated as a lectotype.

Distribution. South Pacific Ocean. Kermadec Trench ( Dahl 1959).
