Pedipalps (commonly shortened to palps or palpi) are the secondary pair of forward appendages among chelicerates – a group of arthropods including spiders, scorpions, horseshoe crabs, and sea spiders.
In spiders, male copulatory organs are separated from the site of sperm production in the opisthosoma. Instead they are shifted to the prosoma, where they are situated on a pair of modified legs, i.e.pedipalps, which are also present in females.

24 paź 2019 · In spiders, the paired male copulatory organs are situated on the pedipalps, which are paired body appendages anterior to the four pairs of walking legs. The use of pedipalps as intromittent organs in males is a synapomorphy for the Araneae [16].
…second pair of appendages, the pedipalps, are modified in the males of all adult spiders to carry sperm (see below Reproduction and life cycle). In females and immature males, the leglike pedipalps are used to handle food and also function as sense organs.
6 maj 2019 · Spiders have evolved a unique male copulatory organ, the pedipalp bulb. The morphology of the bulb is species specific and plays an important role in species recognition and prezygotic reproductive isolation.
In whip spiders, males deposit spermatophores on the substrate for females to collect, which they do using sclerotized claspers from their genitals (Weygoldt, 2000). In this order, pair formation between sexes is a prerequisite for indirect sperm transfer (Chapin & Hebets, 2016).
