ABSTRACT Spiders utilize an indirect method of sperm transfer via specialized male palpal structures. In entelegyne spiders, these structures exhibit a remarkable complexity, comprising various sclerites that interlock with the female genitalia to provide stability and facilitate transfer. Among four primary coupling mechanisms recognized in one, termed self‐bracing, involves interactions between stabilizing expanded copulatory organ during mating. Such can involve elements are not part...
