Microglanis is a genus of bumblebee catfishes native to South America.
Taxonomy
This genus is considered monophyletic by a number of autapomorphies.[1]
Microglanis can be divided into groups of species. For example, the Microglanis parahybae group consist of M. carlae, M. leptostriatus, M. garavelloi and M. parahybae.[2]

Distribution
Microglanis has the widest distribution within the family Pseudopimelodidae, with species ranging from the Guianas, Venezuela, western slope of the Andes in Ecuador and Peru, to the Río de La Plata basin in Argentina.[1] They occur eastward to the Orinoco and Amazon basins.[3] Microglanis is also present in the eastern coastal rivers of Brazil.[3] The M. parahybae group occurs in coastal rivers from the São Francisco River southward to the rio Paraíba do Sul, and in the upper Paraná River basin.[3]
Description
These catfishes are characterized by their small size, which rarely exceeds 70 millimetres (2.8 in) SL.[1] They never reach over 110 mm (4.3 in) SL.[2] They are also characterized wide mouth (same width as the head), small eyes, and short barbels.[3] They are beautifully colored fishes, with a characteristic light band running across the nape and alternate light and dark blotches over the body.[1]
