Hisonotus
Hisonotus is a genus of catfishes (order Siluriformes) of the family Loricariidae.
Taxonomy
Hisonotus and Microlepidogaster have, until recently, been considered as synonymous, although they are now recognized as separate and valid taxa.[1] In the most recent phylogenetic hypotheses, both Hisonotus and Parotocinclus are relatively basal taxa within the Otothyrini clade.[2]

- Hisonotus candombe Casciotta, Azpelicueta, Almirón & Litz, 2006
- Hisonotus charrua Almirón, Azpelicueta, Casciotta & Litz, 2006

Distribution
Hisonotus species mostly occur in Atlantic coastal streams of southern Brazil and the Paraguay-Paraná system of southern South America.[2] They are also distributed in the Río de La Plata basin and coastal rivers of southeastern Brazil.[6]
Description
Species of Hisonotus are the only representatives of the tribe Otothyrini having serrae on the posterior edge of the pectoral fin spine.[2]
Ecology
Hisonotus species are small fishes, generally found in small fast flowing streams, where they grasp to the branches and leaves of aquatic or subaquatic plants.[6]
