Remarks. Han et al. (1985) based their description of Heteronychia helanshanensis upon the holotype 3 and 7 male paratypes from the Helan Shan in Ningxia (China); the holotype is deposited at AMMN. I was unable to examine the holotype, but differences between Heteronychia helanshanensis and H. kozlovi highlighted by Han et al. (1985: 78) appear to be based partly on an insufficient knowledge of S. (H.) kozlovi, and partly on character states that do not justify the description of a new species. On this basis, after comparing original illustrations of H. helanshanensis (Han et al. 1985: 76, figs 1–3) with the holotype of S. (H.) kozlovi, and considering their common origin from the Helan Shan (Neimenggu and Ningxia, China), I propose the above new synonymy.
