A new species of Parotocinclus (Siluriformes: Loricariidae) from the upper Rio São Francisco, Brazil

PABLO LEHMANN A. & ROBERTO E. REIS

Abstract

A new species of the hypoptopomatine loricariid Parotocinclus is described based on material from three rivers belonging to the upper and middle Rio São Francico basin, the Rio das Velhas and Rio JequitaÃ* on the right margin and the Rio Paracatu on the left margin. The new species is readily distinguished from all congeners by having the abdomen completely devoid of dermal plates between the pectoral girdle and the anus, by differences in rostral and postrostral plates, and by having the pectoral girdle covered by skin medially and exposed and supporting odontodes only laterally.

Hi,

die Art ist auch in der Datenbank zu finden: Parotocinclus robustus

Außerdem weisen die Autoren darauf hin, dass sie gerade selber die neue Gattung für die P. longirostris - Gruppe beschreiben, auf die ich schon ein paar Mal hingewiesen habe.
