Alosa vistonica Economidis & Sinis

Thracian Shad (Alosa vistonica)

The Thracian Shad, described in 1986, is, or was, restricted to a single shallow lake, Lake Vistonida in Greece.

The species is highly threatened by sewage, industrial effluents, as well as the destruction of its spawning sites by agricultural development and increased salinity following the opening of a canal into the sea. The species is most likely already extinct.

The photo below shows another congeneric species from the Mediterranean, the Twait Shad (Alosa fallax (Lacepede)).

Tsoukatosia evauemgei Reischütz, Reischütz & Reischütz

EVMG Door Snail (Tsoukatosia evauemgei)  

The EVMG Door Snail (so named after the “Erste Voralberger Malakologische Gesellschaft”) was described in 2012 on the basis of a single subfossil shell that had been found in 2000 in a rubble heap on the Peloponnese in Greece.

The species can be distinguished from its congeners in that the lower lamella is only visible as a straight edge when looking at the mouth at a certain angle.

The shell reaches a height of about 0.98 cm; it is dextral, club-shaped, thin and yellowish white colored.

The EVMG Door Snail may be a cave-dwelling species, and the sole found specimen might be an example that was washed out into the open by the rain. [1]

Eupholidoptera pallipes Willemse & Kruseman

Pale-legged Marbled Bush-Cricket (Eupholidoptera pallipes)

The Pale-legged Marbled Bush-Cricket was described in 1976, it is, or maybe was, restricted to its type locality, apparently near the Linoseli spring in the Lefka Ori Mountains on the island of Crete, Greece.

The species was apparently only ever found once and is now believed to be extinct.

Vinodolia lacustris (Radoman)

Lake Prespa Mudsnail (Vinodolia lacustris)

The Lake Prespa Mudsnail was described in 1973, it was apparently endemic to Lake Prespa, an quite ancient lake that is located between Albania, Greece, and Macedonia.

There are no recent records of this species and it is believed to be possibly extinct.

***

Another species of that genus, which was also presumed extinct, was rediscovered in 2013. [1]

Zonites santoriniensis Riedel & Norris

Santorini Glass Snail (Zonites santoriniensis)

The Santorini Glass Snail was described in 1987 based on subfossil shells that were found in the volcanic deposits of the island of Thira, also known as Santorini, in the southern Cyclades Islands, Greece. [1]

The species seems to have been wiped out by a volcanic eruption that happened at 1450 BC., the same eruption that may have led indirectly to the collapse of the Minoan civilization on the island of Crete, 110 km to the south of Thira, through a gigantic tsunami.

Graecoanatolica macedonica Radoman & Stankovic

Macedonian Freshwater Snail (Graecoanatolica macedonica)

The Macedonian Freshwater Snail was described in 1978, it was endemic to Lake Dojran between Greece and the Republic of North Macedonia, where it was found near the shore in depths between 0 to 50 cm.

The species begun to disappear in the 1970s when the level started to sink due to increasing extraction of lake water for agriculture that led to the complete loss of the species’ habitat.

The last living individuals were finally found in 1992, and the species is likely extinct.

***

The story of the Macedonian Freshwater Snail, however, is not over yet: during the most recent surveys that took place in 2012, only empty shells were recovered, yet some of them appearing very fresh, leading to the hope that some popualtions may still linge somewhere in the Lake. [1]

Zonites embolium ssp. elevatus Riedel & Mylonas

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 ….

Zonites siphnicus Fuchs & Käufel

Sifnos Glass Snail (Zonites siphnicus)

This species, which was described in 1936, is apparently only known by subfossil remains which apparently were recovered from three of the Cyclades Islands, Folegandros, Sifnos as well as Sikinos; each island might have had its own endemic subspecies. [1]

It is, however, surprisingly difficult to find more information about this species.

Elephas tiliensis Theodorou et al.

Tilos Dwarf Elephant (Elephas tiliensis)  

The island of Tilos is located between the islands of Kos and Rhodes in the eastern Aegean Sea.  

This island, like all of the islands in the Mediterranean Sea, once harbored its own, endemic fauna, including dwarfed animals like this endemic Elephant, whose fossil remains were already discovered in the 1970s.  

The Tilos Dwarf Elephant was slightly larger than most other dwarf elephants known from other Mediterranean islands, it reached a shoulder height of about 1,2 to 1,6 m and a length of about 1,9 m.  

The species died out around 3500 B.P., meaning it survived at least until the beginning of the Aegean Bronze Age. It was probably directly hunted to extinction. [1]

Meridiocichla salotti Louchart

Salott’s Mediterranean Thrush (Meridiocichla salotti)

This is rather a Late Pleistocene species that apparently found its last refuge on some of the islands in the Mediterranean Sea, where some of its remains were recovered from Early Holocene deposits. Bones from Corsica and Crete are assigned to this form; additional remains found on the island of Mallorca may also belong here but have not yet been compared.

It was a quite large thrush, larger than any of the living members of the genus Turdus, yet it did not show any signs of insular adaptions like shortened wings etc. and is thus thought to have originally inhabited all of the Mediterranean region. [1]

Islamia graeca Radoman

Greek Islamia Snail (Islamia graeca)

This species was described in 1973; it was endemic to Lake Amvrakia in the Aetolia-Acarnania region on the mainland of Greece.

The species was restricted to the sublittoral zones of the lake; a habitat that today has almost completely fell dry due to over-extraction of water from the lake.

Hydraena sappho Janssens

Sappho Moss Beetle (Hydraena sappho)

The Sappho Moss Beetle was described in 1965, it was restricted to the island of Lefkada, also known as Leucadia, Leukas, or Lefkas, a small island in the Ionian Sea of Greece.

The species is known from only a single specimen and, since it was never recorded since its description, is probably extinct.
