Entomocorus is a genus of catfishes (order Siluriformes) of the family Auchenipteridae.
Entomocorus was first described by Carl H. Eigenmann in 1917 with E. benjamini as type species by monotypy. Only a few phylogenetic diagnoses have been presented since.
Entomocorus is included as the basal member in the Auchenipterus-Group by Carl H. Ferraris; this group also includes Auchenipterus and the sister groups Epapterus and Pseudepapterus. This group is sister to the Ageneiosus-Group, which includes the genera Ageneiosus and Tetranematichthys. These groups, along with the genus Trachelyopterus, form the tribe Auchenipterini. However, the placement of Entomocorus is problematic due to the loss of some characteristics of that diagnose Auchenipteridae and Auchenipterini. Relationships between species of Entomocorus are unknown.
There are currently four described species in this genus:
Entomocorus species are all found in lowlands east of the Andes in South America.
Entomocorus species are small fish, growing to 5.3–7.0 centimetres SL. Sexual dimorphism is evident in all species except for E. benjamini; in this species, transformed males have yet to be found. In the other species, transformed males have stiff, ossified maxillary barbels, an elongated dorsal-fin spine, ventrally-directed pectoral-fin spine hooks, very elongated pelvic-fin unbranched rays, and a rotated anal-fin base.
