DOIAbstract
Oceanic archipelagoes, by their young origin and isolation, provide privileged settings to study the origin and diversification of species. Here, we study the anyphaenid spider genus Philisca, endemic to the Valdivian temperate rainforest, which includes species living both on the mainland as well as on the Robison Crusoe Island in the Juan Fernández archipelago. Anyphaenids, as many spiders, are potentially good colonizers due their ability for ballooning, an airborne dispersal mediated by strands of silk that are caught in the wind. We use a molecular approach to estimate both the phylogenetic relationships and the timeframe of species diversification of Philisca, with the aim to infer its evolutionary history. We further estimate the rat...
