Vipera aspis hugyi is a venomous viper subspecies[4] endemic to southern Italy.

[5] Usually, it is marked with a fused zigzag stripe and has a distinctly raised snout.

Specimens from Montecristo Island, sometimes referred to as V. a. montecristi, are similar, but with a reduced tendency for the dorsal markings to fuse.

[7] Previously, several other common names were used to describe a subspecies that is now part of the synonymy of this form, the Monte Cristo viper[2] or Monte Cristo asp viper[3] for Vipera aspis montecristi.

It is found in Italy in Apulia, Basilicata, Calabria, Sicily and Montecristo Island.
