|
This paper deals with the formal description of a new subspecies of pond terrapin endemic to western Liguria (Emys orbicularis ingauna n. sp.) which is seriously threatened by habitat loss.This new taxon shares with the typical population of E. o. galloitalica the general shell morphology and the plastron colour. Main diagnostic features regard plastron proportions and coloration of carapace, head and front legs. In particular, adult and subadult females show an uniformly chestnut brown carapace, in some cases run by thin blackish lines, while adult males show two phenotypes, both of them characterized by a brownish background. Head coloration is an evident dimorphic feature. In the females the superior region of the head is pale ochre, while the remaining parts show yellow spots and marks on pale gray background; the beak is yellow. In the males the head is dark brown, the superior region and the beak usually lacking any patterns, the sides and the throat showing bright yellow spots; the beak and some other regions (parietal, interorbital and rostral) turn sepia during the mating season. All the females and most males typically show a yellow stripe starting at the elbow and ending between the first two fingers. In most 1 -2 years old individuals the carapace is unusually pale. Two hypothesis on the origin of E. o. ingauna and the conservation measures undertaken are discussed.
