Elevated Glass Snail (Zonites embolium ssp. elevatus)

The subspecies discussed here, was described in 1997 based on subfossil remains, it inhabited at least the two islands of Dyo Adelfoi and Sirna in the Dodecanese Islands in the southeastern Aegean Sea of Greece.

The ‘nominate’ form of this species appears to be nearly extinct as well, it seems to survive only on the island of Megali Zafrano. These island forms, however, most likely represent(ed) distinct subspecies as well.

Unfortunately, it is apparently impossible to find a good map of Greece’s islands or a actual source for binding official island names ….
