Abstract:
Ituglanis goya, new species, is described from the Paranaíba and Tocantins river drainages, central Brazil. This is the first
species of the genus described for the Upper Paraná system and the second epigean Ituglanis for the Tocantins basin. The
new species is distinguished from its congeners by the combination of a color pattern formed by longitudinal stripes and
spots, absence of the anterior cranial fontanel, pattern of the cephalic laterosensory system and several fin-ray counts. Ituglanis
goya exhibits morphological features that oppose the traditional hypotheses of alignment of the genus with the TSVSG
clade of Trichomycteridae. These and other issues concerning the systematics of Ituglanis and the Trichomycterinae
are critically discussed.
