Abstract

Female tabanids are regarded as mechanical vectors of several pathogens and are an important livestock pest. Approximately 4,400 species of tabanids are distributed in all kinds of landscape. Control-limiting methods, including environmental and zootechnical management, require species identification of the flies in a given area. Studies carried out in Thailand have shown a limited species diversity in livestock farms; nevertheless, identification is always difficult when a non-specialist uses dichotomic keys. New user-friendly guidelines recently published, facilitate the description and identification of biting flies. Following these guidelines the most common species, Tabanus striatus, was re-described with emphasis on the key points allowing distinction from the morphologically close T. megalops. In addition, a rich original iconography was provided with 30 pictures of this common biting fly, whose distribution spreads from Pakistan and India to China, and from Lao to Thailand and Vietnam.
