Abstract

A record of the gobiid Orsinigobius punctatissimus (Canestrini, 1864) from the springs of the Gorizia Karst (Italy, Friuli-Venezia Giulia) is reported, extending the eastern limit of the geographic distribution of the species. This goby lives in threatened spring habitats, and has recently become rarer. However, although O. punctatissimus is listed in the Italian Red List of threatened species as “Critically Endangered” (CR), the International Union for Conservation of Nature Red List of threatened species classifies it as “Near Threatened” (NT). Despite its risk of extinction, the species is not included in the annexes of the Habitat Directive (EU Directive 92/43/EEC) or other international wildlife protection conventions. Information is given on the taxonomy, distribution, biology and conservation of the species.
