Abstract

The male cloacal region of Salamandra s. gigliolii is examined by light microscopy. The cloacal cavity exhibits a complex architecture consisting of typical outfoldings and recesses, which correspond to the secretion sites of specific accessory glands. These are the dorsal, pelvic, Kingsbury's, and ventral glands. The hypertrophy of these secretory components, particularly of the dorsal and ventral ones, contributes to form the cloacal swelling of the male during the reproductive season. The morpho‐functional characteristics of the cloacal structures in Salamandra are discussed in comparison with members of the same and other urodele families.
