Material examined. Three parthenogenetic females from Bera Lake , Pahang (3.13704° N, 102.60639° E), 01.02.2018 .

This is the first record for Malaysia. Studied specimens have a body shape typical of the species ( Fig. 6F), morphology of valves ( Fig. 6G), head pores ( Fig. 6H), labrum ( Fig. 6I) and postabdomen ( Fig. 6J). The species is very close in morphology to Anthalona spinifera but differs from this and all other East Asian species of the genus in long posterior setae on valves ( Fig. 6G), with the last setae located at postero-ventral angle of valves, followed by 15 short setulae only. For detailed description see Sinev et al. (2023).

Anthalona vandammei is a rare endemic of South-East Asia, previously known from Lake Kud-Thing in Bueng Kan Province, North-East Thailand, and in Thungtong swamp in Surat Thani Province, Southern Thailand (Sinev et al. 2023). The species is associated with macrophytes.
