| Summary: | Chydorus cf. biovatus Frey 1985 (fig. 7 J–L). Common in spring and autumn, occurs in waterbodies of any type. Eurybiotic littoral species, sometimes encountered in pelagic zone. The first record for China. Ch. cf. biovatus belongs to the Chydorus sphaericus species complex. Species of the sphaericus -complex in Eurasia have identical morphology of parthenogenetic females, but might be distinguished by male and ephippial female morphology (Belyaeva & Taylor, 2009; Klimovsky & Kotov, 2015; Kotov et al. 2016). A single male (Fig. 8 J) was found in a lake (S6) in spring; the individual had a rounded rostrum (Fig 8 K) and a weak preanal angle in the postabdomen (Fig. 8 L) typical for the species. Ch. biovatus s. str. is widely distributed in the Nearctic, but populations with a similar morphology have been reported in Yakutia and Kamchatka (Korovchinsky et al. 2021). For description see Klimovsky & Kotov (2015). ... : Published as part of Dadykin, Ivan A., Sinev, Artem Y., Gu, Yangliang & Han, Bo-Ping, 2023, Spring and autumn fauna of Cladocera (Crustacea: Branchiopoda) in the center of East Asia plain: Hunan and Hubei Provinces of China, pp. 1-25 in Zootaxa 5380 (1) on page 17, DOI: 10.11646/zootaxa.5380.1.1, http://zenodo.org/record/10212806 ... |
