Abstract: Facultative paedomorphism is regularly observed in salamanders, including newts of the Lissotriton vulgaris group. We document the first record of paedomorphism in L. (v.) kosswigi from a locality near Karasu, in the vicinity of Sakarya, Turkey. We compare measurements of 5 paedomorphic individuals with those of 10 metamorphic individuals from the same population and with measurements taken from the literature. Paedomorphs are on average bigger than metamorphs; intriguingly, the opposite pattern has been observed in the Turkish L. (v.) schmidtlerorum.
