"Astyanax" is a
genusof freshwater fishin the characid family (family Characidae) of the order Characiformes. Some of these fish, like many of their relatives, are kept as aquariumpets and known collectively as tetras. With roughly 100 described "Astyanax" species and new ones being described every few months, this genus is among the largest of the entire order: " Hyphessobrycon" has about the same number, and which one is larger at any one time depends on whether more species have been recently described in one or the other. [de Lucena (2003), Nelson (2006)]
The blind cave fish, a form of "A. mexicanus," is a famous member of this genus. "A. jordani," a different but closely related blind fish, was formerly considered to form its own genus, "Anoptichthys."
type speciesis "A. mexicanus," the Mexican tetra. The generic name comes from Astyanax, a character in Greek mythologywho was the son of Hector of Troy; in homage to this, several specific names also refer to the " Iliad".FishBase (2006)]
Taxonomy and systematics
This genus is more or less defined as in 1917 by
Carl H. Eigenmann. The lack of comprehensive phylogenetic analyses dealing with this genus is hindering a thorough review, and the relationships remain as indeterminate as the monophylyis doubtful. [de Lucena (2003)]
