Empis sibillina Bezzi, 1899: 133 (original description)

Diagnosis. Greyish species with dark brown-blackish legs, four strong, long notopleurals; male with palpus long, somewhat projected with strong, long setae, halter yellowish; female with halter brownish black, fore femur with short anterodorsal and posteroventral pennations, mid tibia with posteroventral group of a few minute spine-like setae basally.

Type material and lectotype designation. The original description ( Bezzi 1899) was based on both sexes from central Italy, but the number of specimens was not given. In the Bezzi collection ( MCNM), one male and three females are present. The male and two females are labelled “Tennacola” (according to Bezzi : non rara in maggio nella valle del Tennacola , nei Sibillini , a 1300 m = not rare in May in the Valley of the Tennacola, on the Sibillini mountains at 1300 m); the male and one female with the date “30.v.97”, the other female was also collected in May 1897 but the day is not readable. The third female is labelled “29.v.97” with the locality not readable. Specimens are conspecific and considered syntypes. The male specimen is herewith designated as lectotype of the species and labelled accordingly to fix and stabilize the current concept of the name. The three females become paralectotypes and labelled accordingly.

Additional material. 4 ♂ “ Corse, forêt de Sorba, 16.vi.1976, S. Kelner-Pillault réc.; chemin près du torrent, carte 90, pli 7; Muséum Paris” ; 5 ♂ “ Corse, Gorges de la Restonica , 01.vi.1972, L. Matile réc.” ; 1 ♂ “ Corse, rte. [= road] N. 194, col de Verde, Zicavo , 16.vi.1976, S. Kelner-Pillault réc.; Muséum Paris” ; 1 ♂ “ Corse, Canaglia , près du pont dessus du torrent, 16.vi.1976, S. Kelner-Pillault réc.; Muséum Paris” ( MNHN) .

strong, long antero- and posterodorsal and antero- and posteroventral setae; mid tarsus with 2 ventral rows of spines; mid tarsomeres 1–3 with strong apical setae. Hind femur with rather strong, short anteroventral setae; hind tibia with antero- and posterodorsal rows of rather strong setae as long as tibia depth; hind tarsus with 2 ventral rows of spine-like setae; hind tarsomere 1 with long antero- and posterodorsal setae.
