KRYPTOLEBIAS (Costa 2004)

Genus: Kryptolebias    Family: Rivulidae     Class: Actinopterygii     Phylum: Chordate    Order: Cyprinodontiformes

Type species: Fundulus brasiliensis (Valciennes, 1821

 

   Perhaps the most interesting practice found within Kryptolebias is the hermaphroditic behavior of at least one species (Kryptolebias marmoratus).  There has been some speculation other species may also display this.  Most species are plant-spawning.

The majority of Kryptolebias species are located in the warm regions of South America, but at least one species is found throughout the Caribbean and into the southern parts of the United States along the gulf coast states.

 


– LITERATURE –

Kryptolebias, new name, is Proposed to replace Cryptolebias Costa, 2004, preoccupied by Cryptolebias Gaudant, 1978, a monotypic genus of European fossil fish. As a consequence, Kryptolebiatinae is erected, Substituting Cryptolebiatinae Costa.

Cryptolebias Costa, 2004 which recently erected to include at assemblage of species Previously Placed in Rivulus Poey, 1960. This assemblage which hypothesized to be the sister group of the clade Including all other rivulids, receiving subfamily status, and consequently Cryptolebias which formally designated as the the type genus of the Cryptolebiatinae (Costa, 2004). HOWEVER, Cryptolebias is preoccupied.

The name was first published for a monotypic genus of fossil fish from Europe by cyprinodontoid Gaudant

(1978). Come in, it is the name Proposed Kryptolebias as a substitute generic name for Cryptolebias Costa, 2004, with Fundulus brasiliensis Valenciennes, 1821 as the type species. Consequentely, it is the Proposed new subfamily name Kryptolebiatinae for the family level taxon Containing Kryptolebias, as the type-genus.
