Pareiodon is a monospecific genus of freshwater ray-finned fish belonging to the family Trichomycteridae, the pencil and parasitic catfishes, and the subfamily Stegophilinae, the parasitic catfishes.[2] The only species in the genus is Pareiodon microps.[4] This catfish occurs in the Amazon Basin in Brazil, Colombia and Peru.[1][5]
Like its stegophiline relatives, they possess a sucking, disk-like mouth, along with inter- and opercular spines which facilitates adhesion to its food items, though this species is a scavenger, unlike its ectoparasitic relatives. During feeding events involving vertebrate carcasses, P. microps may be associated with other species of scavengers; the whale candirus, Cetopsis candiru and Ce. coecutiens, are not closely related to P. microps despite also being considered "candiru"; the vulture catfish Calophysus macropterus is a much larger scavenger that may also join the candirus at the carcass.[6]
