Földvári, Peregovits, Kőrösi [genitalia of one male in a plastic microvial with glycerol]. Description. Measurements in mm: body length 2.43 ( holotype ), 2.30-2.40 ( paratypes ); wing length 3.06 ( holotype ), 2.77–2.85 ( paratypes ); wing width 1.02 ( holotype ), 0.92–1.00 ( paratypes ). Head . Prefrons (facial plate) and gena ochrous, covered by dense whitish microtrichia. Occiput concave, meeting vertex at a sharp angle; female prefrons slightly lighter yellowish. Postfrons yellowish brown to brown, shining, its microtrichia are fine and scarce. Ommatrichia less dense and shorter than 0.015 mm . Gena not particularly narrow, below eye slightly more than 1/2 width of pedicel and much less broad than scape. Genal setae less numerous in 1 row (more on postgena): 1 very long just behind the level of anterior edge of eye, plus a similarly long more posteriorly on genal middle height, plus c. 5 shorter but still distinct setae. Antennae all dark, even arista brown. Scape slightly bulbous, somewhat shorter than broad, without distinct setae. Pedicel much widening towards apex, with several apical-subapical setae, longest (dorsal) seta 0.11 mm . First flagellomere sub-spherical, rounded apically, definitely longer than broad (high), 0.15 mm * 0.135 mm . First flagellomere covered by medium long ( 0.025–0.03 mm ) cilia. FIGURES 32–40. Poecilovitila barbata sp. n. , male genitalia. 32 = pregonite, lateral view, 33 = subepandrial sclerite with contours of epandrium, surstyli and cerci, ventral view, 34 = ejaculatory apodeme, lateral view, 35 = surstylus, broadest inner (medial) view, 36 = apical part of surstylus in higher magnification, same view, 37 = ejaculatory apodeme, dorsal view, 38 = phallapodeme, dorsal view, 39 = postgonite, broadest extension, 40 = epiphallus and left postgonite, caudal view with right postgonite in a view between lateral and caudal. Scales: 0.2 mm for Figs 33–35, 0.1 mm for Figs 32, 36–40. FIGURES 41–47. Poecilovitila brevicornis sp. n. , male genitalia. 41 = subepandrial sclerite with contours of epandrium and surstyli, anterior subventral view, 42 = surstylus, broadest inner (medial) view, 43 = hypandrium, basiphallus and phallapodeme, dorsal view (pre- and postgonites omitted, the pair of connecting sclerites to pregonites dashed), 44 = pregonite with hypandrium, lateral view, 45 = postgonite, caudal view, 46 = same, true lateral view, 47 = ejaculatory apodeme, lateral view. Scales: 0.2 mm for Fig. 41, 0.1 mm for Figs 42–47. Thorax. Mesonotum and scutellum brown (not dark), granulose, i.e. not shining. Stutellum strongly narrowing apically, not granulose. Dorsal half of anepisternum and entire anepimeron brown (slightly darker than mesonotum), katepisternum and meron, as well as smaller ventral parts of anepisternum and anepimeron dull yellow. Wing. Ve i n R 2+3 strongly thickened medially and touching costa ( Fig. 113 ), i.e. closing cell r1 entirely, vein R2+3 0.033 mm thick. Wing membrane brown, darker (but still not dark brown) below edge of R1, around white spot, behind R4+5, and basally. White spot much longer than wide (0.22 vs 0.14). Veins dark brown with vein M and A pale. Length of costal sections (all wing measurements in mm) between R1 and R2+3 1.23, between R2+3 and R4+5 0.835, between R4+5 and M1+2 0.36, inter-crossvein section indistinct, basal costal seta arcuate 0.19 mm , costal seta 0.077, length of basal cell 0.23, length of discal cell 0.37, distance between apices of M veins 0.74 mm ; cell r1 0.05 mm at narrowest, there vein R2+3 0.033 mm thick. Costa continued 0.022 mm past apex of R4+5. Costal setula on wing apex bent 0.165 mm . M3+4 only slightly recurved sub-basally. Halter dark brown, stalk ochreous. Legs yellow, femoral apices light brown. Abdomen . Dark brown with sternites paler. Ventral components of the postabdomen entirely membranous. Male genitalia . Subepandrial sclerite ( Fig. 41 ) rather small. Surstylus ( Fig. 42 ) short boat-shaped, with a group of longer, rounder apical pegs, and with 8 blunt pegs on the inner surface of its medial edge. Pregonite ( Fig. 44 ) relatively large, particularly compared to hypandrium, which is short and robust ( Figs 43–44 ). Postgonite 8 ( Fig.45– 46 ) with rather intricate apical part: rather broad in true lateral view ( Fig. 46 ), actually with a subapical process ( Fig. 45 ). Left ribbon of the mesophallus with dense medium-long setae. Phallapodeme ( Fig. 43 ) very short but fused strongly to hypandrium, pregonite and basiphallus (the pair of connecting sclerites to pregonites stressed on that figure). Ejaculatory apodeme ( Fig. 47 ) with rather membranous rod, its curvature in lateral view is in all probability a consequence of the hydroxide maceration of the genitalia of a somewhat teneral male. Female postfrons yellowish brown, prefrons yellowish. Etymology. The specific epithet of this new species refers to its comparatively short antenna.
