Three artotrogids (Crustacea: Copepoda: Siphonostomatoida) from the Ross Sea, Antarctica
The Artotrogidae, one of the most primitive of siphonostomatoid families, consists currently of 117 species in 21 genera. Most of these species (65%) are poorly or incompletely described since they have been rarely recorded in recent decades and, when encountered, have been found in very low numbers...
