A common phytophilous species inhabiting lotic waterbodies of any type in Hunan and Hubei , is abundant in both spring and autumn. Few ephippial females were found in spring in a lake (S24). A cosmopolitan species found in North Eurasia , East Asia, North Africa and North America. In China S. mixtus was recorded in Heilongjiang Province only, but not in the central part of the country ( Xiang et al. 2015 ). However , the species could be misidentified as the widely distributed S. vetuloides Sars, 1898 . For a description see Orlova-Bienkowskaja, 2001 .
