A brief introduction of Chinese Hygrobatidae taxonomy is reviewed. A new species, Sinibates xinyaoae Li, Smit & Guo sp. nov. from Hainan province is described representing a new genus Sinibates Li, Smit & Guo gen. nov. A second species, Hygrobates (Minibates) cf. dobriyali Pešić & Smit, 2019, from Hunan province represents a new subgenus, Minibates Li, Smit & Guo subgen. nov. inHygrobates. The other new species, Mixobates neoamurensis Li & Guo sp. nov. from Inner Mongolia Autonomous Region adds a newly recorded genus, Mixobates Thor, 1905 from China.

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 Arrhenoseius Walter & Lindquist, 2000 is recorded for the first time from the Oriental Realm on the basis of two new species. Arrhenoseius hallidayisp. nov. can be distinguished from other species of the genus by the ventrianal shield bearing five pairs of ventral setae and unsclerotised ventro-lateral cuticle without setae in the adult female, and Arrhenoseius granulatussp. nov. can be distinguished by the ventrianal shield bearing eight pairs of ventral setae and unsclerotised lateral cuticle with six pairs of setae. A key to species of Arrhenoseius is given based on the adult females. [ABSTRACT FROM AUTHOR]

Dambullaeus hainanensis Xu & Jin sp. nov. is described and illustrated based on larvae ectoparasitic on Delphacidae (Hemiptera) from Hainan Island, China. A modified generic diagnosis of larval Dambullaeus is provided and a key to the species of larval Dambullaeus is presented. [ABSTRACT FROM AUTHOR]
