Thesprotian Minnow

The Epiros minnow is a small fish with a maximum standard length of 6.2 cm (2.4 in).

The Epiros minnow is endemic to the Western Balkans, where it is found in the northeastern Aegean Sea basin in Albania and Greece, including Corfu. On the mainland its range extends from Vjosa in Albania to the Acheron in Greece. Pelasgus minnows in Laka Zazari (el. Ζαραβίνα) and the nearby portion of the upper Thyamis are thought to be the possibly extinct P. epiroticus. This species, like other members of its genus, prefers slow-moving to near-stagnant water bodies with abundant aquatic vegetation. These are mostly small streams, spring-fed wetlands and oligotrophic lakes, which can be located at altitudes from sea level to upland plateaus. It is also able to colonise artificial drainage canals. Some populations live in non-perennial streams and small rivers, where they spend the dry periods in residual pools or perennial spring-fed stretches.

The Epiros minnow belongs to the genus Pelasgus. This name is derived from the Pelasgians, the ancient people who lived around the Aegean Sea before the arrival of the Indo-European speaking ancestors of the Greeks in the second millennium B.C.E., and alludes to the fishes in this genus all being found in the Balkans. The specific name, thesproticus, means "of Threspotia", a reference to the type locality.
