From Practical Fishkeeping:
Japanese scientists have described two new species of the gobiid genus Trimma from southern Japan.
From the same magazine:
A new species of spotted freshwater stingray has been described from the Corantijn River drainage in Suriname.
Ricardo Rosa, Marcelo de Carvalho and Cristiane de Almeida Wanderley name the new stingray Potamotrygon boesemani after the late Dutch ichthyologist Marinus Boeseman for his contribution to South American ichthyology in the latest issue of the journal Neotropical Ichthyology.
New anostomid named Leporinus venerei
A new species of Leporinus tetra has been described from central Brazil by Brazilian scientists in the most recent issue of the journal Neotropical Ichthyology.
Still from Practical Fishkeeping:
A new species of cave trichomycterid catfish has been described from central Brazil by Brazilian catfish experts Maria Bichuette and Eleonora Trajano.
The new species, named Ituglanis mambai, is described from a cave in the Mambaí karst area in Goiás State, Central Brazil in the latest issue of the journal Neotropical Ichthyology.
Again, from you guess where:
Scientists from Brazil have described three new species of the loricariid catfish genus Neoplecostomus from the upper Paraná River drainage in southern Brazil.
Prior to this study by Cláudio Zawadzki, Carla Pavanelli and Francisco Langeani published in a recent issue of the journal Zootaxa, only one species of Neoplecostomus, N. paranensis, was known from upper Paraná River drainage.
Finally, from the same source:
The taxonomy of the South American killifish genus Leptolebias has been the subject of a detailed study by Brazilian killifish expert Wilson Costa.
Costa’s study, which is published in the most recent issue of the Zoological Journal of the Linnean Society, recognizes that Leptolebias is not monophyletic, and described a new genus, Notholebias, for three species formerly placed in Leptolebias: L. minimus, L. fractifasciatus, and L. cruzi.
He also describes a new species, Leptolebias itanhaensis, from the coastal plains of São Paulo, in southern Brazil.
A camera crew has recorded the first ever moving pictures of a giant stingray species. The smalleye stingray was seen swimming off the coast of Mozambique, in Africa, by a team filming for the BBC: here.
