Mentissa gracilicosta Rossmässler, 1836

Mentissa gracilicosta Rossmässler, 1836 View in CoL

All Mentissa species are endemic to the Mountainous Crimea. In 1994, Andrii Shklyaruk found M. gracilicosta View in CoL in Odesa near the Mother-in-Law Bridge (Pioneer Park, now Greek Park, or Greek Square). A sample of M. gracilicosta View in CoL from this locality, collected in 1999, is deposited in SMNHL ( Gural-Sverlova & Gural, 2020 a). Perhaps the species was brought to Odesa from Crimea along with grape seedlings ( Sverlova et al., 2006). It is significant that in the same biotope other species of land mollusks were found, previously known in Ukraine only from Crimea, namely Cecilioides raddei (Boettger, 1879) View in CoL and Phenacolimax annularis (Studer, 1820) View in CoL . It can be assumed that there was a joint unintentional introduction of several species.
