[edit] 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]

[edit] Species

There are 16 species in this genus:[3]

  • Genus Hisonotus Eigenmann & Eigenmann, 1889.
    • Hisonotus chromodontus Britski & Garavello, 2007.[4]
    • Hisonotus depressicauda (Miranda Ribeiro, 1918).
    • Hisonotus depressinotus (Miranda Ribeiro, 1918).
    • Hisonotus francirochai (Ihering, 1928).
    • Hisonotus hungy Azpelicueta, Almiron, Casciotta et al. 2007.[5]
    • Hisonotus insperatus Britski & Garavello, 2003.
    • Hisonotus laevior Cope, 1894.
    • Hisonotus leptochilus Cope, 1894.
    • Hisonotus leucofrenatus (Miranda Ribeiro, 1918).
    • Hisonotus luteofrenatus Britski & Garavello, 2007.[4]
    • Hisonotus maculipinnis (Regan, 1912).
    • Hisonotus nigricauda (Boulenger, 1891).
    • Hisonotus notatus Eigenmann & Eigenmann, 1889.
    • Hisonotus paulinus (Regan, 1908).
    • Hisonotus ringueleti Aquino, Schaefer & Miquelarena, 2001.
    • Hisonotus taimensis (Buckup, 1981).

[edit] 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]

[edit] Description

Species of Hisonotus are the only representatives of the tribe Otothyrini having serrae on the posterior edge of the pectoral fin spine.[2]

[edit] 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]
