A new species of Sybistroma Meigen (Diptera: Dolichopodidae) from the Middle East with a key to West-Palaearctic species of the genus Grichanov, Igor Ya. Kazerani, Farzaneh Zootaxa 2014 3866 4 572 582 7QLW 310648 Meigen, 1824 Meigen 1824 [234,529,762,787] Insecta Dolichopodidae Sybistroma Animalia Diptera 1 573 Arthropoda genus   Remarks. See Brooks (2005)for generic diagnosis and synonymy. Unfortunately, combining species from different genera with  Sybistroma, Brooks (2005: 120)was inaccurate in checking gender endings, using all genders: masculine ( eucerus, flavus, inornatusetc.), neuter ( lorifer, obscurellum, sphenopterum) and feminine (  setosa). The gender of  Sybistromacannot be neuter, as Meigen (1824)proposing a new genus, originally included  Sybistroma nodicornisin the genus (a neuter gender of the name is nodicorne). Later only three species were described in this genus with clearly defined gender, all with feminine ending (none with masculine or neuter endings):  S. setosaSchiner, 1862,  S. americanaSchiner, 1868, and  S. lenkoranica Negrobov, 1979. We follow here Schiner’s and Negrobov’s proposal, using the feminine gender for all species names.
