English title: Diversity of chewing lice in seven duck species and three geese species inhabiting Chile

Anatids (ducks, geese) host a great lice diversity. However, there is scarce knowledge about the lice diversity in Chilean ducks, geese, and swans. Here, we describe the lice species parasitizing seven species of duck and three species of geese inhabiting Chile. Among all sampled anatid species, we found eight lice species. The Yellow-billed Pintail (Anas georgica) and Upland Goose (Chloephaga picta) hosted a higher richness of lice species (n = 4). The Blue-winged Teal (Spatula discors) and Chiloé Wigeon (Mareca sibilatrix) hosted only one species of louse each. The lice Anaticola crassicornis and Trinoton querquedulae parasitized the higher number of anatid species (six and five, respectively). The records of Acidoproctus rostratus and Holomenopon leucoxanthum are new for Chile. We identified sixteen new lice-anatid associations, eight of which are new worldwide. In addition, our findings allow us to extend the geographic distribution of five species of lice previously recorded in Chile.
