Mites of the superfamily Pygmephoroidea (Acari: Heterostigmata: Neopygmephoridae, Pygmephoridae) associated with Trox cadaverinus (Coleoptera: Trogidae) from the Far East of Russia, with description of a new genus and two new species

Abstract

Three species of the superfamily Pygmephoroidea (Neopygmephoridae: Pygmephoridae), phoretic on Trox cadaverinus Illiger (Coleoptera: Trogidae) are recorded from the Far East of Russia. A new genus, Troxodania Khaustov and Trach gen. nov. (Neopygmephoridae), and 2 new species, Troxodania magnifica Khaustov and Trach sp. nov. and Pseudopygmephorellus troxi Khaustov and Trach sp. nov. (Pygmephoridae), are described. Bakerdania sinanii Sevastianov and Zahida Al Douri, 1989 (Neopygmephoridae) is considered as a junior synonym of Troxodania decumanus (Krczal, 1959) comb. nov. The key to genera of neopygmephorid females which have median genital sclerites is provided. The taxonomic significance of the median genital sclerite in females of the family Neopygmephoridae is discussed.
