Sturisoma is a genus of armored catfishes native to Central and South America.


Sturisoma has been shown to be sister to Farlowella.[1]

There are currently 15 recognized species in this genus:[2]

Sturisoma aureum (Steindachner, 1900)
Sturisoma barbatum (Kner, 1853)
Sturisoma brevirostre (C. H. Eigenmann & R. S. Eigenmann, 1889)
Sturisoma dariense (Meek & Hildebrand, 1913)
Sturisoma festivum G. S. Myers, 1942
Sturisoma frenatum (Boulenger, 1902)
Sturisoma guentheri (Regan, 1904)
Sturisoma kneri Ghazzi, 2005
Sturisoma lyra (Regan, 1904)
Sturisoma monopelte Fowler, 1914
Sturisoma nigrirostrum Fowler, 1940
Sturisoma panamense (C. H. Eigenmann & R. S. Eigenmann, 1889)
Sturisoma robustum (Regan, 1904)
Sturisoma rostratum (Spix & Agassiz, 1829)
Sturisoma tenuirostre (Steindachner, 1910)


The species of the genus Sturisoma are widely distributed on both slopes of the Andes, in Panama and Colombia, and in the Amazon, Orinoco, and Paraná River basins.[1]

Sexual dimorphism includes hypertrophied odontodes on the sides of the head of the male.[1]

Sturisoma inhabit gently to swiftly flowing white waters where submerged wood is abundant in the main flow of rivers.[1] Sturisoma species are open brooders.[1]
