DNA barcoding lately have been become as an alternative method to assist in the
identification of species. A DNA barcoding is a short gene sequence taken from
standardized region of the genome, used to identify speices. The fly family Tabanidae
(horse flies) includes an estimated 4500 extant species distributed throughout the
world. The biology and taxonomy of horse flies has an important historical legacy but
modern phylogenetics-based revisionary work has lagged behind other dipteran
groups due to a generational reduction in the number of horse fly taxonomists and to a
perceived ‘difficult’morphology which is often homogeneous for many standard
dipteran characters and highly adapted in others. The literature on the Tabanidae
fauna of Turkey, it was found that 171 species and 15 subspecies have been reported.
In this study, Tabanus bifarius, Tabanus bromius, Tabanus glaucopis were analyzed.
PCR was carried out to amplify by using COI gene region. Phylogenetic analyses
were conducted using the Neighbor-Joining method in MEGA5. The bootstrap
consensus tree inferred from 1000 replicates is taken to represent the evolutionary
history of the taxa analyzed. This study we showed that use of DNA sequences in a
systematic could be useful for preventing misidentifications among species.
