Material examined. HOLOTYPE, 3 labelled: “ RUSSIA: N Caucasus/ Krasnodarskiy Kray/ Kamishanova Polyana [44°10'7"N, 40°2'43"E]/ 2–6.vii.2010, Shamshev” (ZIN). PARATYPES: RUSSIA: Krasnodarskiy Kray, Sochi Distr., near Khosta, Akhun Mt. [43°33'02'' N 39°50'36'' E, about 600 a.s.l.], forest, 3–8.vii.2008, P. Tomkovich (1 3, ZMMU); same locality as holotype, 7.vii.2009, Gladun V.V. (1 3, 1 Ƥ, ZIN); same locality as holotype, 22–23.vi.2010, Gladun V.V. (15 3, 1 Ƥ, KSU); same locality as holotype, 2–6.vii.2010, Shamshev (3 3, 5 Ƥ, ZIN); same locality as holotype, 18.vi.2011, Shamshev (1 3, ZIN).
Recognition. Shiny black species with short scape of antenna; palpus yellow; mesonotum with black setae, scutum shining; male legs unmodified, almost entirely yellow.
Description. Body length 2.9–3.2 (in holotype 3.1) mm; wing length 3.4–3.6 (in holotype 3.5) mm. Male (Fig. 3). Head black in ground-colour, occiput, vertex, ocellar tubercle and face finely greyish pollinose. Eyes dichoptic, separated by broad frons, almost touching on face, lower ommatidia enlarged. Frons densely brownish pollinose, nearly twice as broad as anterior ocellus, with marginal setulae. Ocellar tubercle with 2 rather long setae and several minute setulae. Occiput with sparse black setae of different lengths on upper part and pale hair-like on lower part. Antenna black; scape with short setae, nearly 1.5X longer than wide, 1.5X longer than pedicel; pedicel with short setae; postpedicel long, nearly 3.5X as long as wide, with convex ventral margin and straight dorsal margin; stylus short. Proboscis almost entirely yellow, only labrum brownish apically, nearly as long as head height; palpus yellow, with scattered dark setulae.
Thorax black in ground-colour; scutum (except notopleuron and prescutellar depression) shiny, otherwise thorax finely greyish pollinose. Prosternum and proepisternum bare. Antepronotum with several short fine setae. Postpronotal lobe with 1 strong, black seta and several short, thin setulae. Mesonotum mostly with black setae, including 1 presutural supra-alar, 2 notopleurals (posterior seta longer, as long as apical scutellars), 1 short postsutural supra-alar, 1 short postalar, 4 scutellars (apical pair long, lateral pair short); additionally, notopleuron with several pale, short, thin setae anteriorly; acrostichals short, arranged in 2 irregular rows, sparse, lacking on prescutellar depression; dorsocentrals arranged in 2 irregular rows, nearly as long as acrostichals, prescutellar pair somewhat longer. Laterotergite with pale setae.
Legs long, slender, nearly entirely yellow, only apical tarsomeres of fore and mid tarsi, apex of hind tibia and entire hind tarsus brownish. Coxae and trochanters covered with pale, ordinary setae. Fore femur, tibia and tarsus covered with ordinary setulae, lacking strong setae; fore basitarsus slightly thickened. Mid femur nearly as wide as fore femur, with similar setation. Mid tibia with several black, spinule-like ventral setae on apical quarter. Mid tarsus slender, covered with ordinary setulae. Hind femur somewhat narrowed on basal third, bearing short, ordinary setae. Hind tibia slightly thickened apically, lacking strong setae (except subapicals). Hind tarsus slender, with ordinary setulae.
Wing hyaline, anal lobe weakly developed, anal angle obtuse; costal seta rather short, thin; stigma indistinct, brownish yellow; veins R5 and M1+2 parallel near wing margin; radial fork rather broad; vein CuP+CuA incomplete; discal cell elongate apically. Calypter yellow, with pale setae. Halter yellow.
Abdomen largely brown, sternites 1–4 yellowish brown to yellow; covered with pale setae (intermixed with some black fine setae on sternite 8); posteromarginal setae hardly prominent (except tergite and sternite 8); pregenital segments unmodified. Terminalia (Fig. 4) small, brown; cercus covered with short setae, strongly produced anteriorly; epandrium subtriangular, with several long setae along lower margin; hypandrium large, well sclerotised, bare; phallus short, very thick.
Female. Similar to male, except face broader, nearly 1.5X as broad as anterior ocellus; ommatidia equally small; abdomen covered with shorter setae; sternite 6 and entire segments 7–8 greyish pollinose. Cercus long, narrow, black, covered with short setulae.
Etymology. The name of the new species refers to the area of its origin, Krasnodar Territory.
Distribution. Russia: Krasnodar Territory.
Remarks. The new species is similar to E. (L.) insularis Chvála, 2002 (known from Crete and Mallorca) sharing a short scape of the antenna, extensively yellow and unmodified legs of the male, and yellow palpus (Chvála 2002). However, E. (L.) krasnodarensis sp. nov. can be readily distinguished from E. (L.) insularis by the largely shiny scutum. Additionally, the new species has black mesonotal setae (vs. pale yellow in E. (L.) insularis), slightly thickened fore basitarsus of the male and yellowish brown to yellow abdominal sternites 1–4. Empis (L.) cuneipennis Bezzi, 1899 (known from southern Europe) differs from the new species by the entirely shiny mesonotum, brown palpus and colour of the legs.
