Abstract
The family Torrenticolidae belongs to Lebertioidea (Trombidiformes: Hydrachnidiae), one of the most abundant groups in species diversity in water mites (Krantz & Walter 2009). Up to now, the world’s total number of known torrenticolid species is 618 (Gu et al. 2019c, 2022a, b, c; Gu & Guo 2019; Pešić et al. 2019, 2020a, b, 2022). The earliest taxonomic study of Torrenticolidae started in 1837 (Koch 1837), but that in China started later in the 1990s (Jin 1997; Gu & Guo 2019). Therefore, the taxonomy of Torrenticolidae in China is relatively backward. As of December 2016, only 13 torrenticolid species were identified in China. So there are still many new taxonomic categories to be discovered. In addition, some other critical scientific problems are required to be solved quickly, such as limited available morphological characteristics and taxonomical methods.
