Contribution to the Stigmaeidae (Acari: Prostigmata) Fauna of the Altai Republic, Russia

Abstract

During a study of predatory mites of Western Siberia, 13 species of the family Stigmaeidae (Acari: Prostigmata) have been recorded from the Altai Republic, Russia. Stigmaeus akimovi sp. n. and Eustigmaeus summersi sp. n. are described as new to science. Mediolata uspenskii and Eustigmaeus acidophilus have been recorded from Russia for the first time and redescribed based on materials from Altai. Stigmaeus purpurascens, S. longipilis, S. sphagneti, S. delaramae, Mediolata pini, Eustigmaeus segnis, E. rhodomelus, E. parvisetus and Cheylostigmaeus sp. have been recorded from the Altai Republic for the first time.

Review of the Mediolata (Acari: Stigmaeidae) of Russia

“…This species is widely distributed in the Holarctic and was recorded from Austria, Azerbaijan, Canada, Egypt, Italy, Latvia, Moldavia, Poland, Russia, Switzerland, Turkey, Ukraine and the USA (Beron 2020). In Russia, it was recorded from the European part (Wainstein and Kuznetsov 1978) and the Altai Republic (Khaustov 2021a).…”

Two new species and a new synonym of Eustigmaeus (Acari: Stigmaeidae) from Russia with COI barcode

“…The genus Eustigmaeus Berlese, 1910 is one of the largest in the family Stigmaeidae. It comprises 119 described species (Beron 2020;Khaustov 2021aKhaustov , b, 2022, nineteen of which have been reported from Russia (Khaustov and Tolstikov 2014;Khaustov 2016Khaustov , 2019Khaustov , 2021aKhaustov , b, 2022.…”
