These genera are Bineurus Simpson, 1900 (5 species), Isannaia gen. nov. (2 species), Lannanaia gen. nov. (1 species) Namkongnaia Jeratthitikul et al., 2021 (2 species), Nyeinchanconcha Bolotov et al., 2020 (1 species), Pilsbryoconcha Simpson, 1900 (9 species), Pseudodon Gould, 1844 (9 species), Songkhlanaia Konopleva et al., 2023 (1 species), Sundadontina Bolotov et al., 2020 (12 species), and Thaiconcha Bolotov et al., 2020 (3 species). Pseudodon mekongi (Bolotov et al., 2020) was nested within a clade of Pseudodon vondembuschianus (Lea, 1840) in the phylogenetic analysis in this study. Therefore, we recognize it as a subspecies of P. vondembuschianus.
