A review of Venezuelan species of Hypophthalmus (Siluriformes: Pimelodidae)

Morphological variation in Acestrorhynchus microlepis and A. falcatus (Characiformes: Acestrorhynchidae), reassessment of A. apurensis and distribution of Acestrorhynchus in Venezuela

An analysis of morphological variation in Acestrorhynchus microlepis over most of its distribution in South America and A. falcatus from northern drainages of the continent reveals broad variation, yet overlapping values among characters prevented us from identifying additional species among major drainage basins.
