Sars 1904: 63–63, Pl. 34, Figs. 3a–c View FIGURE 3 . Kořínek 1971: 286–289, Figs. 8A–F View FIGURE 8 ; Kořínek 1983: 89–90, Figs. 104–107; Kořínek, Sacherová & Havel 1997: 15; figs. 2C, 4F; Kotov et al. 2009: 19–21, Figs. 9–10 View FIGURE 9 View FIGURE 10 .

Material examined. Several parthenogenetic females from a tin-mining lake in Dengkil , Selangor (2.86975° N, 101.6685° E), 5.10.2013 GoogleMaps ; numerous parthenogenetic females from Batu Dam reservoir, Selangor (3.27472° N, 101.691° E), 30.11.2014 GoogleMaps ; numerous parthenogenetic females from Bukit Merah reservoir, Perak state (5.04147° N, 100.6582° E), 26.01.2018 GoogleMaps ; several parthenogenetic females from a pond at Taiping , Perak state (4.85679° N, 100.7518° E), 04.12.2014 GoogleMaps ; numerous parthenogenetic females from Garden Lake, Taiping , Perak (4.91688° N, 100.7122°E), 26.01.2018 GoogleMaps .

This is the first record for Malaysia. Studied specimens have the morphology typical of the species ( Figs. 3E–F View FIGURE 3 , 4C–F View FIGURE 4 ), including characteristic position of lateral head pore ( Figs. 3G View FIGURE 3 , 4D– E View FIGURE 4 ) and rounded frontal head pore ( Fig. 4F View FIGURE 4 ). Bosmina (Liederobosmina) meridionalis is the only species of subgenus Liederobosmina present in the East Hemisphere, the taxon was first described from Australia and New Zealand ( Sars 1904) and is common in the Indo-Malaysian Province ( Sanoamuang 1998; Maiphae et al. 2008; Tanaka & Ohtaka 2010; Chattergee et al. 2013). For the description of female see Kořínek (1983, 1999) and for the description of male see Kotov et al. (2009).
