New data on the reproductive biology as well as results of the first captive breeding of very rare Asian pitvipers from Truongson Mountains: Protobothrops cornutus and Triceratolepidophis sieversorum are given. Characteristics of the reproductive biology of Protobothrops cornutus and Triceratolepidophis sieversorum, which are sympatric in Truongson Mountains (karst regions of Quang Binh Province) are discussed in the present paper. The data on copulation, gestation and incubation, clutches, size and weight of newborn snakes, temperatures during hibernation and the activity periods, temperature of incubation, a diet during different seasons for different age groups are given in the result of a successful breeding in the laboratory. The descriptions of size of eggs and structures of a shell are provided.
