Remarques

épipélagique.
Soyer-Gobillard (1965, p.223) décrit une femelle (Lg.: 0,83 mm) prélevée à Banyuls, et dont la chétotaxie ne coïncide pas avec celle donnée in Boxshall (1979). Si cette forme n'est pas considérée comme une espèce nouvelle (peut-être une anomalie), ce serait la première localisation en Méditerranée. Par contre les individus que j'ai récoltés à Banyuls (C.R) sont tout à fait conformes à la description de l'espèce.
