Abstract

A new species of Hyphessobrycon is described from tributaries of the río Portuguesa, río Orinoco Basin, Venezuela. The new species is diagnosed from congeners by the presence of two large hooks on each side of the anal fin in adult males (processes of last unbranched and first branched anal-fin rays), distal third of caudal-fin black except for its distal tips (which are hyaline), anal-fin rays v,19–21, and dorsal-fin rays ii,8. Comments on its generic status and putative relationships are provided.
