Abstract |
Truncatelloidea Gray, 1840 (Caenogastropoda: Littorinimorpha) is a superfamily of
gastropods, which includes representatives that live primarily in aquatic ecosystems (marine,
brackish and inland) and are usually distributed in just a single or a few sites. As a result, many
taxa are endemic, or often stenotopic endemic, and due to severe damage to their habitats a
lot of them are threatened with extinction. In Greece, this superfamily is poorly studied and
thus our knowledge about the diversity and distribution of aquatic Gastropods in our country
remains limited.
The present study aims to enrich our knowledge regarding Truncatelloidea of Greece, with
emphasis on their biogeographical distribution in our country, based both on bibliographical
references as well as on specimens from the collection of the Natural History Museum of
Crete and fresh collected specimens.
305 scientific papers by Greek or foreign authors about malacofauna of Greece and adjacent
regions covering the period of 1832-2022, half of which were published during the last 20
years, were studied. Then a database with all the data obtained was created and various
biogeographical analyses were applied.
According to our results 149 valid species of Truncatelloidea occur in Greece, while 43 more
are referred to as taxonomic problems or undetermined. The endemism rates of genera
(30.6%) and species (86.6%) are the highest recorded for an animal non-marine group in
Greece, highlighting the importance of this superfamily. Springs and ancient oligotrophic
lakes (Trichonida, Pamvotida, Megali Prespa and Mikri Prespa) came out to be hotspots of
endemism and biodiversity.
After the dissection of the soft body of male and female specimens from both the collection
of the Natural History Museum of Crete and from sampling on the islands Kea, Anafi and
Paros, two different species of Pseudamnicola coming from the first two islands and two
populations of Ecrobia maritima from Paros were identified. The latter species is reported for
the first time in this island, while there is also evidence that the population of Pseudamnicola
from Anafi represents a new species.
