Description
Simocephalus (Echinocaudus) exspinosus (De Geer, 1778) s. l.
(fig. 5 A–G).
A littoral phytophilous species, is relatively abundant in both spring and autumn in ponds, lakes and more rarely inhabits rice fields. S. exspinosus is a cosmopolitan species (Orlova-Bienkowskaja, 2001; Korovchinsky et al. 2021) occurring in North and South Eurasia, Africa and Australia. It is a new record for Central China, the species was previously found only in the northern part of the country (Xiang et al. 2015). For a description, see Orlova-Bienkowskaja (2001). According to this study, in the Palearctic S. expinosus coexists with its sibling-species S. congener (Koch, 1841) which differs only in the morphology of the postabdominal claw, having a pecten of 20-25 smaller spines on the outer side instead of 8–12 in S. expinosus. In our material, we found specimens with intermediate number of spines (15–18), thus we consider these taxa as synonyms.
