Five species of Unionicola Haldeman, 1842 (Acari: Hydrachnidia: Unionicolidae) were collected between 2018 and 2019. Notably, Unionicola (Armatax) armata Walter, 1929, previously unrecorded in China, is now documented for the first time in the country. Additionally, Unionicola newsumi Wiles, 1999 has been reclassified and assigned to the new subgenus Vespicola within the genus Unionicola Haldeman, 1842. These findings also led to the establishment of three new subgenera: Micronodusgen. nov., Vespicolagen. nov., and Lingshuiataxgen. nov. including four species: Unionicola soluplatussp. nov. U. jinisp. nov. U. caudipessp. nov. and U. armatallasp. nov. This marks the first description and documentation of these subgenera and species. [ABSTRACT FROM AUTHOR]

The genus Dyneogamasus is transferred to the subfamily Pergamasinae, and the generic diagnosis is revised. A new mite species, Dyneogamasus serratus Yao & Jin sp. nov., is described and illustrated based on females from Fujian province, China. A key to the known species of the genus is given.

This paper further enriches the taxonomic study of Feltriidae Viets, 1926 in China since it was first reported by Yi & Jin in 2011. Seven species, Feltria hanmaensis sp. nov., Feltria pesici sp. nov., Feltria pseudoparva sp. nov., Feltria expendis sp. nov., Feltria yinjiangensis sp. nov., Feltria neoflatheadensis sp. nov. and Feltria glandulosa sp. nov., are described as new to science; Feltria minuta Koenike, 1892 is new to the Chinese water mite fauna. In addition, some slit organs of these species are photographed by SEM (scanning electron microscope) and illustrated in detail by optical microscope to provide material for exploiting valuable character in specific identification.

Two new water mites species of the genus Sperchon Kramer, 1877 from China, Sperchon synsetus sp. nov. and Sperchon xiaoqikongensis sp. nov. are described and illustrated in this article. Sperchon synsetus sp. nov. differs from known species of the genus in the following: cuticle covered with very fine spinules arranged in polygonal pattern and each polygon with an annular line inside; two peg-like setae fused at the base on the ventral side of P-IV. Sperchon xiaoqikongensis sp. nov. is characterized by cuticle covered with scale-shaped papillae; P-II with an obtuse projection bearing three setae and A1 setae is plumose. To the present, 18 species of the genus Sperchon have been described from China. [ABSTRACT FROM AUTHOR]

Three new aturid species are described and illustrated from China: Woolastookia allobasilicalabricasp. nov., and Paraxonopsis suturasp. nov. in the Axonopsinae, and Aturus jixiensissp. nov. in the Aturinae. The genus Paraxonopsis is a newly recorded genus for the Chinese fauna. Woolastookia allobasilicalabricasp. nov. is the third species and Aturus jixiensissp. nov. is the second species in their respective genera from China. A key to the Chinese fauna of Aturidae is provided in this paper. Meanwhile, the diagnosis of Paraxonopsis is revised. [ABSTRACT FROM AUTHOR]
