The term Corydoras paucerna does not appear in major taxonomic databases, scientific literature, or reputable encyclopedic sources as a recognized species or subspecies within the genus Corydoras (family Callichthyidae). Consequently, there is no verifiable information regarding its description, distribution, ecology, or conservation status.
The name may be a misspelling or a non‑standard vernacular label. The genus name Corydoras is derived from Greek roots meaning “leather skin,” reflecting the armored plates of these South American catfishes. The specific epithet “paucerna” does not correspond to any documented Latin or Greek terms commonly used in zoological nomenclature, and its etymology cannot be reliably determined without a formal description.
In the absence of a valid scientific reference, any further details about Corydoras paucerna would be speculative.
