Figure 1 Terminology of key morphological characters for Theodoxus. A. Shell: a = apex, ap = aperture (im = inner margin, om = outer margin), cp = columellar plate, p = periostracum, s = spire, sh = shell height, sm = shell margin, sw = shell width, w = whorls; B. Operculum: ap = apophysis, ca = callus, cb = calcareous base, cl = conchioline lamella, la = left adductor, pa = pseudo-apophysis, ra = right adductor, rp = rib-pouch, rs = rib-shield; C. Radula: ac = A-central (c = cusp, r = ridge, tp = tooth plate), bc = B-central, cc = C-central, el = E-lateral (le = lower edge, ue = upper edge), mt1 = first row of marginal teeth (sf = small face of marginal teeth), mt2 = second row of marginal teeth, rc = R-central (ae = anterior edge, f = tooth face).
Figure 2 from: Sands AF, Glöer P, Gürlek ME, Albrecht C, Neubauer TA (2020) A revision of the extant species of Theodoxus (Gastropoda, Neritidae) in Asia, with the description of three new species. Zoosystematics and Evolution 96(1): 25-66. https://doi.org/10.3897/zse.96.48312
Figure 2 Dated phylogeny of the genus Theodoxus constructed with BEAST, based on existing GenBank and newly incorporated data for COI, 16S and ATPα (Suppl. material 1: Table S1). Morphospecies where associations are queried are highlighted by a question mark after the species name (see the "Systematic checklist" for more information). Small green (PP ≥ 0.95) and red (PP < 0.95) dots on nodes indicate the relative posterior probability support of divergence events. Node labels (1–32) correspond to divergence dates and HPD intervals in millions of years ago (Mya) for selected nodes (see Suppl. material 1: Table S3). Dashed dark blue and light blue lines represent the minimum interspecific and maximum intraspecific variation determined by Sands et al. (2019a) to aid Theodoxus spp. delimitation (see see Methods, Phylogenetics and species delimitation and that study for more information on the delimitation methods).

Figure 3 Occurrence map for Theodoxus spp. in Asia. All points conform to specimens used in the phylogenetic analyses (Suppl. material 1: Table S1), except for T. gloeri for which no molecular data are available and only the type and paratype localities are indicated.
