A review of Fedrizzia mite species (Acari: Mesostigmata: Fedrizziidae) found in association with Australian Mastachilus beetles (Coleoptera: Passalidae)

Abstract

Mites of the genus Fedrizzia from passalid beetles of the genus Mastachilus are reviewed, and two new species, Fedrizzia classeni sp. nov. and Fedrizzia humei sp. nov. are described, both associated with Mastachilus polyphyllus (Macleay, 1826). Fedrizzia oudemansi Womersley, 1959, is redescribed and shown to occur only on the southern form of Mastachilus australasicus (Percheron, 1841); previous records of this mite from M. polyphyllus are placed in F. classeni. A revised key to Fedrizzia is presented. © The State of Queensland, Queensland Museum 2013.
