A new species of Neurigona Rondani, 1856 (Diptera: Dolichopodidae) with a key to species from Iran and adjacent countries

A new long-legged fly species, Neurigona parchamii sp. n., from the southwestern Iranian province of Khuzestan is described and illustrated. The new species appears to be closely related to N. euchroma Negrobov, 1987 known from Uzbekistan, differing from this species by the following characters states: body somewhat longer; fore coxa with yellow bristles apically; mid femur with posteroventral row of mainly yellow bristles, mostly longer than femur height, and the shape of the hypopygium and its appendages. Neurigona euchroma has a fore coxa with black bristles at apex; mid femur with ventral row of mainly black bristles, shorter than femur height, and 1–2 light setae at base. A check list and key to 17 species of the genus Neurigona Rondani, 1856 of Iran and neighbouring countries are compiled
