Tabanus petiolatus is a species of horse fly in the family Tabanidae. Unlike many Tabanus species, the colour pattern of male eyes is found in the larger, upper lenses - appearing as a dark, brown streak across the light coloured lens. Females of this species have uniformly coloured dark brown eyes. Often confused with Tabanus melanocerus or Tabanus trimaculatus.
