Two new species of Sciapus Zeller, 1842 (Diptera: Dolichopodidae) from Iran

Abstract

Two new long-legged fly species, Sciapus basavandae sp. nov. and S. khuzestanicus sp. nov. from Sistan and Baluchestan and Khuzestan provinces of Iran are described and illustrated. The two new species appear to be very close to S. sylvaticus Becker, 1907, known from Algeria, differing from the latter in body size, mostly yellow antenna; wider face, abdomen partly yellow, bilobed surstylus, cercus with ventral projection. S. sylvaticus has black antenna, narrow face, entirely dark abdomen, simple and thick surstylus, cercus without ventral projection. A check list and key to 24 Sciapus species of Iran and neighbouring countries are compiled for the first time.
