Wang ” [CWBS 282, 283]. Remarks. This species has been originally described from Sichuan by Jiang and Chen (2023). The material from Guizhou Province (Fig. 10 A – E) is here tentatively identified as Zaitzeviaria cf. muchuanensis. Although the specimens from Guizhou agree quite well with the specimens from Sichuan in external characters, they are on average smaller (Guizhou: BL 1.21–1.39 mm; Sichuan: BL 1.25–1.46 mm). In addition, the median lobe (Fig. 10 C – E) appears to be thinner and usually slightly shorter (0.46–0.5 mm) than in specimens from Sichuan (0.50–0.54 mm), less distinctly subbasally curved, and the lateral sinuation appears to be placed further proximal (close to the middle) and is marked by a tiny excision lacking in specimens from Sichuan. More detailed morphological studies and the use of molecular data will be necessary to clarify whether the specimens from Guizhou are conspecific with Z. muchuanensis or whether they represent an undescribed species.
