Remarks.
The specimens match the general morphology of Monatractides xiaoxiensis Gu & Guo, 2019, a species from China ( Gu et al. 2019b). Monatractides xiaoxiensis is characterized by: frontal platelets trapezoidal, shoulder platelets triangular; only the tip of Cx-I and Cx-II exceeding to the anterior margin of idiosoma; tips of Cx-I with an elongated cuticle extension; gnathosoma dorsal apodeme long with a blunt end, ventral apodeme pointed and bent towards dorsum; bs curved heavily towards ventrum ( Gu et al. 2019b). According to these characters, we believe our specimens from Zhejiang Province are M. xiaoxiensis . The only differences are found in V4, which is away from the line of primary sclerotization in Zhejiang specimens, but close to the line in Hunan specimens.
