Introducing a New Catfish, Scleromystax reisi
30 Sep, 2016
A new species of catfish from the genus Scleromystax is described today in the journal Neotropical Ichthyology, the official journal of the Sociedade Brasileira de Ictiologia (SBI). The formal description of Scleromystax reisi has been published in the article New species of Scleromystax Günther, 1864 (Siluriformes: Callichthyidae) – extending the meridional distribution of genera endemic to the Atlantic Forest, by Marcelo R. Britto, Clayton K. Fukakusa, and Luiz R. Malabarba.
This species occurs in “several coastal river basins from southern Bahia to southern Santa Catarina States,” which extends the southern reach of the entire Scleromystax genus.
The authors suggest that the species is likely not rare, but may have specific habitat requirements within its range, stating, “the species is well [established] but in very selective habitats associated with preserved riparian vegetation.” The authors of the description do note that, per IUCN classifications, they believe that the newly-described species would be a species of “Least Concern” on the IUCN Redlist.
When discussing this charming new species today, AMAZONAS Magazine Sr. Editor and Translator Stephan Tanner noted, “The fish is certainly neat and close to Scleromystax macropterus. It has probably not yet been imported, and is unlikely to be seen because there are no collectors there and Scleromystax is in part protected.”
For further details and insights on this new catfish species, please review the full description of Scleromystax reisi in the journal Neotropical Ichthyology.
