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 ).
