Light red: possibly extant Yellow: extinct Fundulus letourneuxi Sauvage, 1880 Valencia letourneuxi, the Corfu toothcarp, is a species of fish in the family Valenciidae.

[1] The specific name of this fish honours the collector of the type, the botanist Aristide-Horace Letourneux (1820-1890).

[3] The species was described as Fundulus letourneuxi in 1880 by Henri Émile Sauvage with a type locality of Cressida, Corfu.

[4] It also formerly occurred on the island of Lefkas but is now considered to be extirpated from both there and Corfu.

[5] While little is known of its ecological history, V. Letourneuxi produce 2.2 mm eggs during the spring on aquatic plants in stagnant water that has a lot of vegetation.
