Abstract
Rivulus staecki, a new species of the subgenus Owiyeye, is described from the upper Rio Negro drainage in southern Venezuela (Estado Amazonas). It differs from the other species of the subgenus by a unique combination of character states: a truncate caudal fin, elongated pelvic fins in males, presence of a ‘rivulus spot’ in both sexes and 35 – 38 scales in the longitudinal series.
