            <p>Distribution and Ecology. Up to date, P. j e j u e n s i s sp. nov. is known from two close localities on Jeju Island. No similar species were found in nearest regions of China (Chiang &amp; Du 1979), Far East of Russia (Kotov et al., 2011a–b), Japan (Uéno 1926, 1937; Tanaka 1994) and continental South Korea (Kotov et al. 2012). The species seems to be endemic of this island.</p>
            <p> The information on localities is given in Tables 1–2. It is remarkable, that at two different dates  P. jejuensis sp.nov. occurred both in the river and in the puddles from the swampy area. It means that it could be present in water bodies of different type. In November it co-occurred with six other species of cladocerans in stony pools (remnants of the almost dried Daseong river, Fig. 1 F). Unfortunately, our sampling covered only the winter season, no data are available on these localities in summer, i.e. at the monsoon time. </p>
