    Abstract

    Creagrutus nigrotaeniatus n. sp. is described from the rio Juruena basin, upper rio Tapajós system, Mato Grosso State,
    Brazil. Creagrutus nigrotaeniatus differs from its congeners by having the dentigerous surface of the premaxilla longitudinally
    elongate from ventral view, 4–5 post-anal scales and 2–4 maxillary teeth. The new species also has the anterior
    margin of hyomandibula straight or slightly concave which is a unique condition within the genus, and possesses a series
    of non-exclusive osteological modifications (e.g. medial opening of the dentary foramen located distinctly anteroventral
    to the tip of Meckel’s cartilage; anterior portion of the laterosensory canal segment in first infraorbital terminating distinctly
    posterior to the anterior margin of this bone; presence of the third posttemporal fossa within the epioccipital; one
    epural present). A comparison with Caiapobrycon tucurui is provided and the placement of the new species within Creagrutus
    and its close relationship with C. cracentis, C. gephyrus, and C. maxillaris are discussed.

     

    A copy would be great!
