Entomocorus gameroi is a species of driftwood catfish native (possibly endemic) to Venezuela and questionably present in Colombia. It is found in the Apure River basin. It grows to a length of 7.0 cm and can be distinguished from its congeners by an oblique band crossing from the dorsal profile of the caudal peduncle to the middle-upper rays of the caudal fin. E. gameroi is classified as an omnivore with a tendency towards insectivory; it has been found to eat cladocerans, copepods, and water mites, as well as ostracods, insects including coleopterans, dipterans, ephemeropterans, hemipterans, and seeds and other vegetal matter.
