This study presents a detailed taxonomic review of water mite deutonymphs of the genus Unionicola Haldeman, 1842 (Hygrobatoidea: Unionicolidae) found in the fauna of Russia during the long-term survey period of 1979-2013. The review includes descriptions and illustrations of 14 Unionicola species found in this country: U. aculeata (Koenike, 1890), U. arcuata (Wolcott, 1898), U. bonzi (Claparède...

A new species, Empitrombium makolae sp. nov., is described based on active postlarval forms and larvae obtained from adult females kept in the laboratory. Based on the adult morphology of E. makolae, the adult life stage of Platytrombidium littorale (Michener 1946) is moved back to the genus Empitrombium. A key to species of Empitrombium is provided.

Based on the recent ascertaining studies of type specimens, the new systematic placement for one subgenus and three species of oribatid mites of the family Galumnidae (Acari, Oribatida) are proposed, resulting in the following taxonomic proposals: Pergalumna (Bigalumna) Mahunka & Mahunka-Papp, 2009 stat. nov., P. (B.) rimosa (Mahunka & Mahunka-Papp, 2009) comb. nov., Allogalumna quadrimaculata ...

Three species of Rhodacaroidea are reported from soil in Colombia. Desectophis anthuriumsetis n. sp. (Ologamasidae) and Multidentorhodacarus colombianus n. sp. (Rhodacaridae) are described from newly-collected material. Multidentorhodacarus triramulus (Karg, 1998) is redescribed from the holotype and adult females collected in this study. A key for the separation of females of the five recognis...

Ixodes holocyclus (Acarina: Ixodidae) and Ixodes cornuatus (Acarina: Ixodidae) are two tick species found in the more densely populated areas of Australia and are known to be the cause of the neurotoxic disease tick paralysis in humans and mammals. Borreliosis otherwise known as Lyme disease is an emerging infectious disease in humans in Australia. Borrelia burgdorferi sensu stricto (Spirochaet...
