First record of the hyperparasite Liriopsis pygmaea (Cryptoniscidae, Isopoda) from a rhizocephalan parasite of the false king crab Paralomis granulosa from the Beagle Channel (Argentina), with a redescription

The Cryptoniscidae are epicaridean isopod parasites or hyperparasites of other crustaceans. Liriopsis Schultze in Müller, 1859, one of the genera included in this family, now contains two nominal species: L. pygmaea (Rathke, 1843) and L. monophthalma (Fraisse, 1878). Both of these species infest rhi...
