Spiders have long been noted as classic examples of sexual behavioramong arachnids, including extreme sexual dimorphism in some groups, and behavioraladaptations to diverse mating patterns. In recent decades, studies on the biologyof Neotropical spiders have offered novel information on processes related toreproductive biology, including sexual selection. The present chapter synthesizesthe large amount of knowledge on sexual selection and associated subjects in spidersfrom the Neotropics. Some of the groups considered in this review are mygalomorphs,lycosids and related, orb-weaving species, tetragnathids, social species,pholcids, and oonopids, among others. Concepts, patterns, mechanisms, and prospectson different areas of sexual selection are shown in detail for all these groups.In particular, here we highlight selected examples of the different contexts in whichmale?female interactions occur, such as mate choice, sexual cannibalism, spermcompetition, and cryptic female choice. We outline the potential evolutionary consequencesaccording to those contexts, with a final selection of model groups forspecific experimental and comparative investigations.
