Callicorixa audeni is not a widely recognized taxonomic name in the current scientific literature. The genus Callicorixa belongs to the family Corixidae, comprising aquatic true bugs commonly known as water boatmen. While numerous species within this genus have been described (e.g., Callicorixa alabamensis, Callicorixa lewisii), there is no verifiable record of a species bearing the specific epithet audeni in major entomological databases, catalogues, or peer‑reviewed publications.
Possible contextual interpretation
Etymology: The epithet audeni could plausibly be a patronym honoring an individual with the surname Auden (e.g., the poet W. H. Auden) or a variant of a Latinized name. Such naming conventions are common in taxonomy, but without an original description or citation, the precise origin remains uncertain.
Taxonomic placement: If the name were valid, it would likely be placed within the order Hemiptera, suborder Heteroptera, family Corixidae, and follow the diagnostic characteristics of the genus Callicorixa (aquatic habitat, dorsoventrally flattened body, oar‑like hind legs for swimming, and a predaceous or detritivorous diet).
Conclusion
Due to the lack of corroborating sources, Callicorixa audeni cannot be confirmed as an established species or taxonomic entity. Any further information would require verification from primary taxonomic literature or authoritative databases.
