Review of the genus Dioctria Meigen, 1803 (Diptera Asilidae) from Iran, with four new species records for the Iranian fauna

Abstract

Based on specimens collected, using sweeping nets and Malaise traps, from the East Azarbaijan, Guilan, Alborz and Mazandaran Provinces of Iran between May 2010 and September 2015, six species of the genus Dioctria Meigen, 1803 were collected. They were subsequently identified, and four species: Dioctria arnoldii V. Richter, 1964, D. humeralis Zeller, 1840, D. pilithorax V. Richter, 1980, and D. speculifrons Wiedemann, 1820, had not been previously recorded from Iran. Diagnostic characters and geographical distribution of the newly recorded species are provided. An illustrated key to all known Iranian Dioctria species is given.
