Vitiatus

Vitiatus is a Latin adjective used in biological nomenclature as a species epithet in the scientific names of various organisms. It does not denote a single taxon or group; rather, it is one among many descriptive epithets that authors attach to species names in zoology and botany.

Etymology and meaning: The form vitiatus derives from Latin vitium, meaning fault, defect, or vice. The masculine form vitiatus, feminine vitiata, and neuter vitiatum are used to agree with the gender of the genus. In practice, the epithet may reflect a perceived abnormality, deformity, color variation, or other characteristic noted by the author at the time of description. As with most descriptive epithets, the exact rationale can vary by species and may not reliably indicate current biology or relationships.

Taxonomic usage: Vitiatus appears as an epithet in species names across both zoological and botanical nomenclature. Because it is an adjectival epithet, the same or similar epithet can occur in unrelated genera. When written, the genus name is capitalized and the species epithet is lowercase; the binomial is typically set in italics in scientific writing, though formatting may vary by publication.

Notes: Epithets such as vitiatus are historical and descriptive in origin. Modern taxonomy often emphasizes taxonomy and phylogeny based on objective characters, but traditional descriptive terms remain in use in many groups. For concrete examples, consulting taxonomic databases or original species descriptions is necessary.
