英文摘要	Sexual communication in mate choice scenarios involves nonmutually exclusive functions: species recognition, mate location and mate assessment. Most studies on sexual communication in mate choice have focused on female assessment of conspicuous male traits, such as visual and acoustic signals. Only a few studies have addressed male assessment of female traits, especially those that are inconspicuous to the human sensory system, such as chemical signals. Although chemical signals are important in sexual communication of many arachnids, there is a gap in our knowledge about how male scorpions use these signals to evaluate potential partners. Here we studied sexual communication functions in two scorpion species (Urophonius brachycentrus and Urophonius achalensis) with sympatric populations and synchronic reproduction, where males are under a scramble competition mating system. We addressed the volatile pheromones role in each of the sexual communication functions. We used Y-mazes to test volatile pheromones, exposing males to different female stimulus arrays in single-signal (conspecific only) and mixed-signal (conspecific and heterospecific) contexts. Males located conspecific females through volatile pheromones, and the time spent in proximity to the female was proportional to males' perception of the female's quality, reinforcing the pheromones' function in mate location and assessment in single-signal environments. However, these sexually selected functions were overridden in mixed signal contexts, in which males could not differentiate conspecific from heterospecific females, suggesting that pheromones do not allow species recognition. This interaction between sexual communication functions can lead to reproductive interference in this sympatric zone. Male indiscriminateness mediated by scramble competition could attenuate pheromones' species recognition function during mate choice. We provide a comprehensive study of the pheromones' role for mate and species recognition in different social contexts in scorpions. We found support for nonindependent and interacting functions of sexual communication, indicating that mate choice is a complex process in scorpions.
