Macrovipera schweizeri (Werner, 1935): comparison of the populations of Milos and Sifnos islands (SW Cyclades) (Serpentes Viperidae)
Creators
Description
New evidence and the re-elaboration of old data confirm that the viper of Sifnos is distinct from
that of Milos, Macrovipera schweizeri schweizeri (Werner, 1935), based on its: consistently larger
dimensions, greater number of ventral scales and diverse coloring, as well as differences in the structure
and development of the egg shell (also larger) and the embryos at time of deposit. It therefore
seems plausible to consider it a geographic subspecies in its own right, of the name Macrovipera
schweizeri siphnensis (Wettstein, 1952). The presence of Dolichophis caspius on Sifnos must have
played a key role in this speciation process. For the first time, the effects of the Milos viper’s venomous
bite on man are described as well as its relative treatment. Also noted is the importance of
dry stone walls as an indispensable ecological element for the survival and conservation of the
Cyclades viper.
