Three new species of Apheviderulix gen. nov. and proposal of Apheviderulicidae fam. nov. (Acari : Hydrachnidia : Eylaoidea)

This paper presents descriptions of known instars of three new species of A pheviderulix gen. nov., including larvae and deutonymphs of the type specie s Apheviderulix welwitschioides sp. nov. from Sicily, deutonymphs of A. lep tomastax sp. nov. from Morocco and deutonymphs of A. santana sp. nov. from California. Apheviderulicidae fam. nov. is proposed to accommodate the new genus, and the phylogenetic affinites and classification of this highly dis tinctive taxon are discussed. The host associations of larval Apheviderulix with dytiscid beetles are discussed.
