Pedipalpus

 

one of the second pair of jointed appendages of the cephalothorax of Arachnoidea. In most species, the palpal organ serves to crush prey. Other species have chelate pedipalpi, for example, the scorpions and pseudoscorpions. The true spiders and other species have a simple palpus, whose extreme segment in the males serves as a copulative organ.
