(D) cephalic amplexus of Notophthalmus viridescens (Urodela: Salamandridae). The male grasps the females's neck whilst fan- ning pheromones towards her nostrils. (E) cloacal region of lentic breeding Cynops pyrrhogaster (Urodela: Salamandridae). The male's cloaca (left) is heavily swollen compared to that of the female (right). (F) cloacal region of lotic breeding Euproctus mon- tanus (Urodela: Salamandridae, after Brizzi et al. 1995). Males (left) possess a cloacal protuberance (cp) which bears a protusible pseudopenis (pp), whereas the female cloaca is slightly conical shaped and its opening is located ventrally (right). (G) amplecting pair of Calotriton arnoldi (Urodela: Salamandridae). The male grasps the female's trunk with his tail. Bonn zoological Bulletin 57 (2): 119-126 ©ZFMK.
