On Willowsia View in CoL distribution

Willowsia jacobsoni View in CoL has several records from the Eastern region of the Old World, but it had never been recorded from China mainland ( Fig. 8 View FIGURE 8 ). Due to the main distribution of the genus and the species in the Old World, especially in Asia, we believe that W. jacobsoni View in CoL was possibly introduced in the Americas (including Caribbean and Hawaiian Islands), given its ability to occupy different natural and even anthropic habitats ( Christiansen & Bellinger 1994: 316). This is the case of Brazilian populations herein reported, which was found in urban areas found in urban areas, representing the first record of the species and the genus in Brazil ( Zeppelini et al. 2025). We believe that W. jacobsoni View in CoL was probably also introduced into Africa, since no endemic species of Willowsia View in CoL has been described for the continent to date ( Bellinger et al. 1996 –2024). In the Americas, although there are other species widely distributed (e.g. W. buski View in CoL , W. nigromaculata View in CoL ), the genus has only three species restricted to North America ( W. mexicana View in CoL , W. neonigromaculata View in CoL and W. pyrrhopygia View in CoL ). The distribution data suggest that Asia is most likely the origin center of Willowsia View in CoL , since this region concentrates the greatest richness of the genus, with 37 species (84% of the total).
