Figure *.tif. Schematic visualization for the constrained model selection approaches. The unconstrained phylogenetic hypothesis was tested against four competing evolutionary scenarios in a model selection approach (refer to Table 3). Both scenarios concerning Carychium microgastropods are depicted, since the constraints likewise affected the splitting order of ancient nodes. E = Europe; A = Asia; N+C = North+Central America excl. C. nannodes; N = C. nannodes. Black dots indicate posterior probability ≥ 0.98. A: phylogenetic unconstrained hypothesis. A1a = C. cf. pessimum; A1b = C. nipponense; A2 = Carychium sp.3; A3 = C. cf. noduliferum. B: monophyletic Asian Carychium. C: monophyletic American Carychium. A1 = C. cf. pessimum + C. nipponense; A2 = C. cf. noduliferum + Carychium sp.3.

Figure *.tif. Bioclimatic niche models. The suitable bioclimatic conditions of the native monophyletic North + Central American (A; red) and European (B; yellow) clades are illustrated. Niche projections for these clades and between the areas are depicted in C and D. Black triangles indicated occurrence data of native (in A and B) and schematic snails of introduced taxa (in C). A: Potential distribution of the native North + Central American clade. B: Potential distribution of the native European clade. C: Projected distribution of the European clade in North + Central America. Non-native European Carychium minimum (CM) and C. tridentatum (CT) populations are indicated. D: Projected distribution of the North + Central American clade in Europe.

Table *.xlsx. Non-native Carychium populations in North America. Locality information and literature sources for non-native Carychium populations (based on morphospecies IDs) in North America are listed. Specimens from localities indicated by an asterisk (*) are validated by DNA barcoding as the respective Carychium species [111-116].
