Routes of introduction of Wasmannia auropunctata. Note: Colored dots represent genetically distinct introduced clonal populations. The dark green area represents the native range of W. auropunctata (Wetterer and Porter 2003), and black stars represent areas where populations from the native range have been sampled. The code letter for each introduced country is given in Table 1. Estimated dates of introduction are indicated between brackets when available (see Table S1 for detailed references).
