The robertsi-tetra has a valid name now

22. December 2014

1958 a beautiful and popular tetra from Peru is trade under the name of
“Hyphessobrycon robertsi”. However, this name is a pure invention and
never ever a scientific description for the tetra appeared.

In a
scientific study on the relationship of the “rosy tetras” to which the
robertsi-tetra belongs, Stanley Weitzman and Lisa Palmer suggested 1997
that the fish might be conspecific to Hyphessobrycon bentosi.

Axel Zarske from Senckenberg Museum in Germany has published a new
study on the theme. He compared H. bentosi with the robertsi-tetra
carefully and found a number of differences. So he described finally the
robertsi-tetra under the new scientific name Hyphessobrycon
jackrobertsi as a valid species. The specific name “jackrobertsi” honors
the discoverer of the species, Jack Roberts from Miami, who was already
meant with the invalid name “robertsi”.
