The phylogenetic relationships of Tephritis Latreille, one of the largest genera of true fruit flies, are poorly understood due to the large number of species, lack of reliable morphological characters and difficulties in identification. In the present study we used two datasets to address these problems: one with 35 species of the genus Tephritis...

Species of the genus Tephritis usually have the wing pattern with dark rays on veins R4+5 and M connected to the preapical dark spot or to each other (often called the “apical fork). Some species, however, have a solid apical crossband (Korneyev, 2013), whereas others have an isolated pair of apical spots. Specimens with the latter morphological ch...
