Male. Unknown. Material examined. Holotype ♀, No. AH-TO- 2010052001, Hougu Scenic Area, Tangkou, Huangshan, Anhui, China (30 ° 19 ′ 14 ′′ N, 118 ° 86 ′ 27 ′′ E, elev. 890 m), 20. V. 2010, coll. Xu Zhang. Paratype. 0 / 1 / 0, No. AH-TO- 2010052002, same data as holotype. Habitat. Running water; with many rocks on the bed, and no water plants. Distribution. China (Anhui). Etymology. This new species is named after its flattened, sword-shaped rostrum, “ gladius ” means sword-like, and “ rostrum ” means gnathosomal rostrum. Remarks. The new species is similar to T. acrisarostrum Gu & Guo, 2020 for the ventral processes at P- 2 and P- 3 and respectively with a seta, the short and sharp dorsal apodeme of the gnathosoma, and the thin and pointed rostrum (Gu et al., 2020), butdifferent from the latter by: (1) E 4 flush with the acetabula pair IV (vs. the acetabula pair II in T. acrisarostrum); (2) The ventral apodeme of the gnathosoma short and blunt (vs. relatively long and sharp in T. acrisarostrum); (3) P- 4 with two ventral extensions (vs. only one in T. acrisarostrum).	en	Jia, Lan, Gu, Xinyao, Jin, Daochao, Guo, Jianjun (2023): A newly recorded and a new species of torrenticolid mites (Acari: Hydrachnidiae) from China.

Material examined. 1 ♂ 1 ♀, No. JX-TO- 2009080401 — 02, Huangbitan River, Wuyishan National Nature Reserve, Yanshan, Shangrao, Jiangxi, China (27 ° 50 ′ 53 ′′ N, 117 ° 43 ′ 43 ′′ E, elev. 916 m), 4. VIII. 2009, coll. Hao Zhong. Habitat. Streams, running water, with mayflies, small fish and no water plants. Distribution. China (Jiangxi), South Africa (K. O. Viets 1981). Remarks. The species is recorded in China for the first time. The population in China is almost identical to the South African population (Viets, 1981) except P- 2 with four / three dorsal setae in male / female rather than only one dorsal seta as the drawing of the South African specimen.
