Pareiodon
genus of fishes
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. The only species in the genus is Pareiodon microps. This catfish occurs in the Amazon Basin in Brazil, Colombia and Peru.
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.
The public source identifies “Pareiodon” as genus of fishes. This brief keeps that definition visible, then builds a research path around Pareiodon, genus and fishes.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Pareiodon”, the useful work is to connect “genus of fishes” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 21, 2026. The linked authority identifier is Q18746753.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
