The pineal complex and associated brain structures make up the epithalamus. In embryonic development, they form as an evaginations of the diencephalon roof. The structures of the epithalamus are of great interest among scientists due to their involvement in vital physiological functions of mammalian and other vertebrates. Of particular interest are animals in which the pineal complex has a photoreceptor function and includes a parapineal organ (parietal eye). It is described in lampreys, some teleosts, anurans and reptiles in which it is particularly complex. For the first time, we described the early stages of the development of the paraphysis and epiphysis in a representative of the family Diplodactylidae, the gecko Correlophus ciliatus. These primordia are evaginations of the roof of diencephalon, localized on its anterior and posterior borders. At the same time with epithalamic structures in this area of the brain, a network of blood vessels develops. The formation of a blood sinus in the parietal region of the embryo occurs by the 33rd stage of development, before the appearance of the skull. An analysis of the literature showed that the features of the development of the primordia of epithalamic structures in C. ciliatus are similar to the development of these structures in turtles, in which, like in gecko, the pineal complex does not have a parapineal organ.
