The genus ''Sturisomatichthys'' is distributed in the northwestern part of South America, on the Pacific and Atlantic slopes of the Andes. The species appear to occupy the same ecological niche as those in ''Sturisoma''.Description
Sexual dimorphism and reproductive biology of ''Sturisomatichthys'' similar to ''Sturisoma''. ''Sturisomatichthys'' is distinguished from ''Sturisoma'' primarily by the absence of a rostrum (anatomy), rostrum. Only one species, ''S. citurensis'', from Panama, seems to be significantly different from all congeneric species in having an abdominal plate cover consisting of small platelets without any particular organization. Other species may represent a species complex with a short snout as in the genus ''Farlowella'' with reference to the representatives of the ''F. curtirostra'' group. The weakness of this diagnostic feature could lead to the synonym (taxonomy), synonymy of ''Sturisomatichthys'' with ''Sturisoma''. ''Sturisomatichthys'' species grow to about in length.References
