Sampling and specimens
We analysed a total of 127 Milnesium populations, including 83
newly sequenced. They originate from five continents and nine
zoogeographic realms (according to Holt et al., 2013); from the most
sampled: Afrotropical, Palaearctic, Oriental, Neotropical, Australian,
Madagascan, Panamanian, Nearctic and Oceanian realm (approximate
localities are depicted in Fig. 1, for detailed information see Table
S1).
