The name Pseudolithoxus anthrax does not appear in widely recognized taxonomic references or major encyclopedic databases such as FishBase, the Catalog of Fishes, or peer‑reviewed systematic reviews of Loricariidae. Consequently, it cannot be confirmed as a formally described species or an established scientific concept.
Possible etymology and context
- Pseudolithoxus is a recognized genus of small, armored catfishes (family Loricariidae) native to the river basins of northern South America. The genus is characterized by a dorsoventrally flattened body, a pronounced dorsal ridge, and often vivid coloration.
- The specific epithet anthrax is derived from the Greek word ἀνθράξ (anthrax), meaning “coal” or “charcoal.” In biological nomenclature, this term is sometimes used to denote a dark or black coloration pattern in the organism.
If Pseudolithoxus anthrax were a validly published species, the name would likely refer to a member of the Pseudolithoxus genus with a notably dark or coal‑colored appearance. However, without verifiable taxonomic literature, the existence and diagnostic features of such a species remain unconfirmed.
