Definition
Virbia rotundata is a purported scientific name that appears to refer to a species of moth within the genus Virbia, which belongs to the family Erebidae (subfamily Arctiinae). No widely accepted taxonomic records or peer‑reviewed literature currently confirm the existence or valid publication of this species name.
Overview
The genus Virbia comprises numerous small to medium‑sized moths known for their often brightly colored forewings and muted hindwings. Species in this genus are primarily distributed throughout the Americas, ranging from North America through Central America to parts of South America. While many Virbia species have been formally described, Virbia rotundata does not appear in major taxonomic databases such as the Global Lepidoptera Names Index (LepIndex), the Integrated Taxonomic Information System (ITIS), or recent revisions of the Arctiinae.
Etymology / Origin
- Genus name – Virbia: The etymology of the genus name is not definitively documented in the primary literature. It may be derived from Latin or a constructed name by the original author, but the precise meaning remains uncertain.
- Species epithet – rotundata: The Latin word rotundatus (feminine rotundata) translates to “rounded” or “circular.” In zoological nomenclature, such an epithet typically references a morphological characteristic, possibly indicating rounded wing margins or a body shape.
Characteristics
Accurate morphological, ecological, or distributional characteristics for Virbia rotundata cannot be provided because reliable descriptions are not available in the scientific record. General traits of the genus Virbia include:
- Wing pattern: Forewings often exhibit distinct color bands or spots; hindwings are usually less conspicuous.
- Size: Adult wingspans typically range from 20 to 35 mm.
- Larval host plants: Caterpillars of many Virbia species feed on low‑lying herbaceous plants, though specific host associations vary by species.
Without a validated species description, it is not possible to confirm whether V. rotundata conforms to these generic characteristics or possesses unique features.

Note
Accurate information about Virbia rotundata is not confirmed in the current scientific literature. The name may represent an unpublished manuscript name, a synonym of a recognized species, or a typographical error in secondary sources. Further taxonomic research would be required to determine its validity.
