Material examined. Over 20 parthenogenetic females from Putrajaya Wetland , Putrajaya (2.94434° N, 101.6926° E), coll. in 24.01.2018 GoogleMaps .

This is the first record for Malaysia. The species was previously reported from the same locality by Umi et al. (2020) as B. (Bosmina) longirostris . Studied specimens have the morphology typical of the species ( Figs. 3A–D View FIGURE 3 , 4A View FIGURE 4 ), including characteristic position of lateral head pore ( Fig. 3C View FIGURE 3 ), and horseshoe-shaped frontal head pore ( Fig. 4B View FIGURE 4 ). The species clearly differs from other species found in Malaysia, B. (Liederobosmina) meridionalis , in position of the lateral head pore and shape of the frontal pore. B. (S.) fatalis is endemic to East and Southeast Asia, distributed in Thailand, Cambodia, the Philippines, eastern China, Korea and Japan ( Maiphae et al. 2008; Tanaka & Ohtaka 2010; Korovchinsky et al. 2021b). For detailed description of female see Kotov et al. (2012), for description of male see Kotov et al. (2009).
