Key to the species of Lepidozetes in the Holarctic region

For the Palaeactic and Nearctic regions, five valid species were described; Lepidozetes bavaricus n. sp. is the sixth one. The geographical distributions are cited in the following after Subías (2013): Lepidozetes singularis Berlese, 1910 (Holarctic) ; L. latipilosus Hammer, 1952 (Holarctic) ; L. dashidorzsi Balogh et Mahunka, 1965 (Eastern Palaearctic); L. trifolius (Fujikawa, 1972) (Holarctic) ; L. umbellatus (Bugrov, 1991) (Western Asia). The characters used in the key are taken mostly from the original descriptions, in L. dashidorzsi additionally from Bayartogtokh & Aoki (1999). The structure of the tutorium is not described for L. dashidorzsi and L. trifolius .
