A new trans-Andean Stick Catfish of the genus Farlowella (Farlowella yarigui)

[Acanthicus]

Ballen, GA & JI Mojica, 2014. A new trans-Andean Stick Catfish of the genus Farlowella Eigenmann & Eigenmann, 1889 (Siluriformes: Loricariidae) with the first record of the genus for the rÃ*o Magdalena Basin in Colombia. Zootaxa 3765: 134–142.

Abstract

A new species of Farlowella is described from El Carmen de ChucurÃ* in the Departamento de Santander, western flank of the Cordillera Oriental, rÃ*o Magdalena Basin, Colombia. Farlowella yarigui n. sp. differs from its congeners in lateral body plate morphology, abdominal cover, cephalic hypertrophied odontodes, and details of coloration. This is the first verifiable record of the genus in the Magdalena drainage. Aspects of natural history and implications of this finding are provided concerning the state of knowledge of the fishes of the rÃ*o Magdalena Basin. Previous records of Farlowella gracilis in the rÃ*o Cauca basin are examined and herein considered erroneous, rendering the new species the only representative of the genus in the Magdalena-Cauca system. A key to species of Farlowella from Colombia is provided.

Das scheint eine sehr interessante Art zu sein! Und zwar eine für's Strömungsbecken, nicht wie sonst für "Ast-Stock-und-Pflanzen-Becken". Außerdem hat Farlowella yarigui ein sehr kurzes Rostrum und es bildet sich bei den Männchen ein dichter Odontodenbewuchs an den Seiten des Rostrums, was ihnen das Aussehen eines Spatels verleiht.
