abstract (from publication):
Hypostomus formosae, new species, is described from the Paraguay River Basin and H. boulengeri is redescribed. Morphological and molecular analyses show that these two species belong to the ‘H. plecostomus species group’. Hypostomus formosae can be distinguished from H. boulengeri by having the tip of the snout completely covered with small plates (vs. naked snout tip) and fewer premaxillary and dentary teeth (13-28 vs. 16-32, and 10-25 vs. 15-31, respectively). The molecular phylogenetic analysis indicates that the sister species of H. formosae is H. plecostomus from the Amazon and the Guyanas, highlighting past inter-basin ichthyofauna exchanges.
