( Figs. 2 View FIGURES 1 – 2 , 5–6 View FIGURES 5 – 6 )
Diagnosis. Legs black except apices of femora dark brownish yellow with extreme tips black and bases of tibiae dark brownish yellow. M1 and M2 incomplete, not reaching wing margin. Dorsal arm of male cercus short and thick, subtriangular.
Description. Male. Body length 5.7–7.7 mm, wing length 5.7–7.1 mm.
Head black, pale gray pollinose. Eyes contiguous on frons, dark yellow. Setae and setulae on head black except posteroventral surface with some pale setulae; ocellar tubercle distinct, with one pair of long oc and 4 very short posterior setulae. Antenna black except scape and pedicel slightly paler. Proboscis very long, 2.1 times longer than head height, blackish with black setulae; palpus brownish yellow with black ventral setulae (1 subbasal setula long).
Thorax black, pale grey pollinose; scutum with 3 black vittae. Setae and setulae on thorax black; pronotum with 4 or 6 setae; h long, 3 long npl (anterior 1 npl weak, posterior 2 npl strong), acr mostly long setulae-like and biseriate, 1 longer posterior dc (slightly longer than setulae anteriad) and 7–8 long setulae anteriad, 1 long strong presc (longer and stronger than posterior dc), 1 long sa, 1 long psa; scutellum with two pairs of setae (basal pair short, apical pair long strong). Laterotergite with fan of pale long setulae. Prosternum with some long pale setulae laterally. Legs black except apices of femora dark brownish yellow with extreme tips black and bases of tibiae dark brownish yellow. Setulae and setae on legs black except fore and mid coxae with some pale setulae anteriorly. Fore and mid femora subequal in thickness, hind femur 1.2 times as thick as mid femur. Hind tibia and hind tarsomere 1 slightly thickened. Fore tibia with 1 ad near apex, apically with 1 av and 1 pv. Mid tibia with 5 ad and 3 av (1 av near apex long), apically with 3 setae (1 av long). Hind tibia with two rows of irregular dorsal setae, apically with 3 setae. Hind tarsomere 1 with 2 ad, 2 pd and 4 short spine-like av. Wing nearly hyaline; dark brown stigma long, narrow; veins dark brown, M1 and M2 weak and incomplete. Squama dark yellow, bordered with pale setulae. Halter yellow with brown base.
Abdomen black with pale gray pollen. Setulae and setae on abdomen black except tergites 1–3 with pale long setulae laterally and sternites 2–7 with pale setulae, sternite 1 bare.
Male genitalia ( Figs. 5–6 View FIGURES 5 – 6 ): Epandrial lobe longer than wide, basally rather narrow, apically obtuse. Cercus very large and broad, slightly wider than epandrial lobe in lateral view, distinctly longer than wide in dorsal view; dorsal arm short thick, subtriangular; ventral arm very short, finger-like. Phallus weakly curved upward, apically rather thin.
Female. Unknown.
Type material. Holotype male, Hubei, Shennongjia, Dalongtan, 2009. VI.29, Qifei Liu. Paratypes: 5 males, same data as holotype.
Distribution. China (Hubei).
Etymology. The specific name refers to the type locality.
Remarks. Empis (P.) shennongana can be easily separated from E. (P.) prolongata by the nearly entirely blackish brown femora and tibiae, the entirely black abdomen and the short, thick, subtriangular dorsal arm of the male cercus.
