Three new long-legged fly species, Asyndetus alborzensis sp. nov., A. persicus sp. nov. and A. karkhehensis sp. nov. from Iran are described and illustrated. Asyndetus alborzensis sp. nov. is remarkable in having matt-black frons and face; A. persicus sp. nov. is the third Palaearctic species with two ventral combs of long black bristles on male abdominal sternite 5; A. karkhehensis sp. nov. male is peculiar in distinctly broken apical part of wing vein M1+2; vein dm-m present, and hind tarsus with only one claw. Asyndetus longicornis collected from the Mangrove habitats (Asalouyeh, Bushehr province) is newly recorded from Iran. Asyndetus chaetifemoratus and A. separatus are excluded from the fauna of Iran. A check list and identification key to 19 Asyndetus species of Iran and neighbouring countries are compiled for the first time.
