Nosferatu is a

caecum adhered to a saccular stomach.[1]

All species in Nosferatu had previously belonged to its sister genus Herichthys.[1][3][4][5][6]

Species

There are currently 7 recognized species in this genus:[1]

Phylogenetics

Separate analysis of the mitochondrial gene

polyphyly) composed of the nominal species N. pantostictus.[9] In comparison to Herichthys, high levels of intrageneric divergence and structure
within Nosferatu were revealed.

Evolution

Divergence time for the split between Herichthys and Nosferatu has been estimated in ~5 Mya. During these times (i.e.

endorheic shallow lakes, where Nosferatu evolved into the bartoni (~3 Mya), steindacheri (~2Mya) and pantostictus (~2 Mya) clades. Later on (~1.8 Mya), as regional faulting rejoined the Rio Verde with the Pánuco Basin during the course of the Pleistocene, the genus re-invaded the Pánuco, this time with the evolved mechanisms of reproductive isolation that allows its sympatry with Herichthys.[1]

Name

The name of this genus, Nosferatu, was given because of the pair of well-developed recurved fangs in the upper jaw present possessed by all species of the genus; these were said to be reminiscent of those of the eponymous vampire in F. W. Murnau's Nosferatu.[11]
