A New Species of Scoloplax with a Remarkable New Tooth Morphology
within Loricarioidea (Siluriformes: Scoloplacidae)
Marcelo Rocha, Henrique Lazzarotto, and Lucia Rapp Py-Daniel
Copeia 2012, No. 4: 670 - 677.
A new species of Scoloplax is described with a remarkable new tooth morphology, possessing dentary teeth with four
cusps and premaxillary teeth with two to four cusps, features unique among all Loricarioidea and rare among
Siluriformes. Scoloplax baileyi, new species, is further distinguished by eight diagnostic features. The new species is
found in the small tributaries of Rio Unini, an important tributary to the Rio Negro, and in the Anavilhanas Archipelago,
lower Rio Negro, Amazonas State, Brazil. Based on a review of scoloplacids, a new record of S. baskini is given to include
the Rio Negro, increasing the number of species of Scoloplax from that basin to four.
