Leptolebias marmoratus, (Ladiges, 1934)

History

This rare and delicate species was first described by Ladiges in 1934 as Cynopoecilus marmoratus. Myers transferred this Cynopoecilus marmoratus in 1944 to the genus Cynolebias ( Steindachner) recognizing it as a valid species and a senior synonym of C. sicheleri and C. zingiberinus.

The given type locality was Rio de aneiro, near Rais da Serra, now Inhomirim.

Costa recollected and redescribed the species in 2002.

Due to urbanization of the habitat of this wonderful fish there is a threat to extinction in the wild.
