C. venezuelanus has a large oval green/black spot covering the shoulder and a distinct iridescent reddish-brown spot on the nape. It is a large Cory, and is restricted to a limited range in two closed drainage systems (Rio Tuy and Lake Valencia) situated north of the serrania del interior. It is the only Cory in these waters.
