THREATENED FISH OF THE WORLD: LEUCISCUS LUCUMONIS BIANCO, 1982.

This Italian endemic species has undergone a progressive decline in its original range since it was first described. Leucisus lucumonis is an important biogeographic indicator of the Tuscany-Latium district. At present there are only about 10–12 isolated populations. According to the 2002 IUCN Red List of Threatened Species. www.redlist.org, downloaded on 14 August 2002, the status of this species (erroneously reported as L. lucumontis, Bianco 1983) was listed as at ‘Lower Risk’, (conservation dependent). Today L. lucumonis can be allocated to the endangered category for threatened species as it satisfies paragraph B and point 1 of the IUCN (1996) criterion ‘Severely fragmented distribution’.
