Identifying the various factors that influence complex signal evolution is a difficult task, yet it is fundamental to understanding the evolution of animal communication. Here we explore the evolution of complex courtship signaling by taking advantage of a system in which sexual selection on male courtship traits has driven the diversification of geographically isolated populations of the jumping spider Habronattus pugillis Griswold. Using 2 populations (Santa Rita [SR] and Atascosa [AT]) in which SR females show xenophilic mating preferences for foreign (AT) over local males (SR), we examine the mechanisms driving this preference. Both AT and SR males produce multimodal …
