Abstract
- A new species of Hypostomus with large and spaced light roundish spots is described from the upper rio Paraná basin. Hypostomus multidens new species is distinguished from all remaining congeners with light spots on a darker background by two independent characters: the presence of teeth with two symmetrical cusps, and a high tooth number in each dentary (122267, mean 196.8) and premaxilla (115-260, mean 190.8). Uma nova espécie de Hypostomus com pintas claras grandes e espaçadas é descrita para a bacia do alto rio Paraná. Hypostomus multidens nova espécie distingue-se de todas as outras congêneres com pintas claras em um fundo escuro por duas características independentes: a presença de dentes com cúspides simétricas, e um elevado número de dentes em cada dentário (122-267, média 196.8) e pré-maxilar (115-260, média 190.8).
