Records and distribution of Syscenus infelix in the deep Mediterranean (Crustacea: Isopoda: Aegidae)

Abstract

The parasitic isopod Syscenusinfelix is recorded from the Mediterranean, based on 19 specimens from a depth range of 375–2071 m. The first ovigerous female of the species is also recorded. Patterns of possible parasitism were suggested based on the depth distribution of S. infelix, and their possible host macrourid fish below 900 m depth in the Catalano-Balearic basin.
