Almost all of the species are ectoparasites of soft-bodied invertebrates (e.g. polychaete worms and other molluscs) ( Dinapoli et al. 2011 ). Taxonomic descriptions have been based on the teleoconch morphology and especially on the protoconch according to descriptions and illustrations of Peñas et al. (1996) . Works on the phylogenies of the family are few, which complicates the correct assignment of species to genera.
