Habitat.

Streamlet.

Remarks.

The populations from Zhejiang Province fit the definition of Monatractides macrocorpis Gu & Guo, 2019 (Gu et al. 2019b). Differences with the original description are: (1) the ventral apodeme of gnathosoma, sharp in Zhejiang specimens, but blunt in Hunan specimens; (2) with a red colour pattern in Zhejiang specimens, but purple in Hunan specimens.

Distribution.

China (Hunan, Zhejiang).
