Sarmento-Soares, LM & PA Buckup, 2005. A New Glanidium from the Rio São Francisco Basin, Brazil (Siluriformes: Auchenipteridae: Centromochlinae). Copeia 2005: 846-853.
Abstract
Glanidium bockmanni, new species, is described from the Rio São Francisco basin in Brazil. The new species is distinguished from its congeners by the reduced ossified suprapreopercular canal. It occurs in sympatry with Glanidium albescens in Minas Gerais; the two species differ in relative adult size, pectoral-fin spine serration, fin ray counts, and numbers of ribs and vertebrae. Within Glanidium, the new species uniquely shares with G. cesarpintoi (Ihering, 1928) a color pattern of small dark dots scattered over the body, a smaller adult size (less than 50 mm in standard length), and absence of first nuchal plate.
