Four new species of mites in Ologamasiphis and Holzmannia genera, and a new Juvaria subgenus defined (Parasitiformes: Parasitidae)

The present study proposes the restructuring of Ologamasiphis genus (family Parasitidae) comprising two subgenera Ologamasiphis s. s. and Holzmannia Juvara-Balş, 2002, to have the respective subgenera elevated to the genus level, as well as to have the brand-new Juvaria subgenus created within the Holzmannia genus. The proposed restructuring is based on two newly described species belonging to the genus Holzmannia and subgenus Juvaria n. subgen., to wit Holzmannia (Juvaria) pilosa n. sp. and Holzmannia (Juvaria) silvestris n. sp. Furthermore, two new species belonging to Ologamasiphis genus are described: Ologamasiphis setosus n. sp. and Ologamasiphis zelkovae n. sp. Pertinent modification of the existing key to the Parasitidae genera by Hrúzová & Fenďa (2018) is also supplied.
