Additional file 2: Figure S1. of The evolution of genital complexity and mating rates in sexually size dimorphic spiders

Relatively simple (left; Clitaetra) and complex (right, Herennia) genital morphology in nephilid spiders. Upper images show distal parts of the male pedipalp, lower images show female epigyna. Note that the male embolic conductor (EC) interacts with the copulatory opening (CO) of the female, and if broken off, may form an elaborate mating plug (lower right). (EPS 7104 kb
