Tabanus cymatophorus
Tabanus cymatophorus is a species of horse fly in the family Tabanidae, first described by Osten Sacken in 1876. The species is recognized as valid by major taxonomic databases including GBIF and NCBI, though it was historically listed as a synonym in some sources. As a member of the genus Tabanus, it shares the characteristic large size and biting mouthparts typical of horse flies. Very few observations of this species have been recorded, with only four documented observations on iNaturalist, suggesting it may be rare, geographically restricted, or underreported.
