Brazilian scientists have described a new species of whiptail catfish from the cataracts of the Rio Dara in the Rio Negro drainage, naming it after its type locality.

Lcia Py-Daniel and Ilana Fichberg describe Rineloricaria daraha in the latest issue of the journal Neotropical Ichthyology and distinguish it from congeners in having seven branched pectoral-fin rays, long digitiform papillae on the ventral surface of the lower lip and the presence of a large and multi-angular preanal plate limited anteriorly by four or more variably sized plates much smaller than the preanal plate.

For more information, see the paper: Py-Daniel, LHR and I Fichberg (2008) A new species of Rineloricaria (Siluriformes: Loricariidae: Loricariinae) from rio Dara, rio Negro basin, Amazon, Brazil. Neotropical Ichthyology 6, pp. 339"346.
