Material examined. Several parthenogenetic females from a forest waterbody near Muadzam Shah , Pahang (3.12474° N, 102.9969° E), 18.10.2013 GoogleMaps ; several parthenogenetic females from Chini Lake , Pahang (3.43257° N, 102.9186° E), 19.10.2013 GoogleMaps ; one parthenogenetic female from pond near Pahang river, Pahang (3.44933° N, 103.0478° E), 19.10.2013 GoogleMaps ; several parthenogenetic females from Biru Lake , Selangor (3.24675° N, 101.5265° E), 30.11.2014 GoogleMaps ; three parthenogenetic females from Chini Lake , Pahang (3.42026 ° N, 102.92990° N), 5.09.2022 .

This is the first record for the Peninsular Malaysia. Studied specimens have somewhat higher, more ovoid body ( Fig. 6A View FIGURE 6 ) as compared to the specimens reported from Thailand and Malaysian Borneo, but share a characteristic morphology of labrum ( Fig. 6C View FIGURE 6 ), postabdomen ( Fig. 6D View FIGURE 6 ), and inner distal lobe of limb I bearing remarkable setae 1–2, ending in large spines ( Fig. 6E View FIGURE 6 ). The latter character, shared only by A. vandammei , clearly separates A. spinifera from most of other East Asian Anthalona species. The species is very close in morphology to Anthalona vandammei (see below) but differs from it in the short posterior setae on valves and more numerous setulae (about 25) at postero-ventral angle of valves ( Fig. 6B View FIGURE 6 ).

Rare endemic of South-East Asia, previously known from North-East Thailand (Tiang-nga et al. 2016) and Sabah, East Malaysia ( Sinev & Yusoff 2018). The species is associated with macrophytes. For detailed description see Tiang-nga et al. (2016).
