Coronatella rectangula (Sars, 1862) (= Alona rectangula Sars, 1862). Inhabits

vegetated lotic water bodies of any type, predominantly in spring. Males and ephippial females were recorded in both spring and autumn at localities S4, S7, S32, A22, A34. C. rectangula is a Palearctic species, distributed from Spain to Far East of Russia, common in China. In East Asia, the species penetrates south up to Peninsular Malaysia and Borneo, but South-East Asian populations slightly differ from those of the Palearctic in that they have narrower postabdomen, probably presenting a species-complex (Sinev & Yusoff 2015; Sinev et al. 2015). Common in China (Ji et al. 2015). For description, see Van Damme & Dumont (2008).
