Types. Type material could not be found at the Museum für Naturkunde, Humbolt-Universität, Berlin or at the

Zoologischen Museum, Hamburg, Germany and is considered lost. However, it is a very distinctive species readily

characterized by the description and figures provided by Claus (1879, 1887).

Type locality. Near Zanzibar, tropical south-western Indian Ocean.

Habitat. Marine, pelagic. Reliably known from trawls with 50–1500 mw (meters of wire out). Associations. There are no records of associations with gelatinous plankton which are often hosts for hyperiidean amphipods.

Distribution. Indian Ocean: off Zanzibar (Claus 1879). Atlantic Ocean: near the Azores (Spandl 1927); off southwestern Africa (08°26’N 15°11’W), 600 mw, (Zeidler 2016). Pacific Ocean: just north-east of the Galapogos Islands (02°52’N 87°38’W), 50 & 300 mw (Zeidler 2016); just north-west of the Kermadec Islands (27°00’S 177°41’W), 1500 mw (Zeidler 2016). South China Sea: (07°13.5’N 111°49’E), 1000 mw (Zeidler 2016).
