Abstract

Myoglanis aspredinoides n. sp. is described from the Río Ventuari, upper Orinoco in Venezuela. The new species is distinguished from the other species of the genus by its elongated body with 56 to 57 vertebrae, long anal fin with 32 to 35 fin rays, lanceolate caudal fin and distally serrated anterior margin of pectoral spine.Se describe Myoglanis aspredinoides n. sp. proveniente del Río Ventuari, alto Orinoco en Venezuela. La nueva especie se diferencia de las otras especies del género por poseer un cuerpo alargado con 56 a 57 vértebras, aleta anal larga con 32 a 35 radios, aleta caudal lanceolada y margen anterior de la espina pectoral aserrado distalmente.
