Description. Measurements in mm: body length 2.75 (holotype), 2.95–3.10 (paratype males), 3.08—3.41 (paratype females); wing length 3.12 (holotype), 2.85–3.20 (paratype males), 3.30—3.63 (paratype females); wing width 0.94 (holotype), 0.93–1.00 (paratype males), 1.00—1.07 (paratype females).
Head (and consequently eyes) much longer than high. Minimal width of prefrons slightly more than its height. Prefrons above mouth edge seems dirty white as a consequence of very dense whitish microtrichia, this coverage continues without any break to genae and postgena; face with dark stripe dorsal to whitish band, becoming ochreous to lunule; transition between the dark and lighter colour is sharp in a number of specimens (not including the holotype). Postfrons yellowish brown, shining, and terminating in a sub-triangular narrowly rounded apical margin (over lunule). Ommatrichia short but discernible. Gena oblique in lateral view, very narrow. Genal setae: 1 long seta behind anterior edge of eye, other 2 similarly long setae plus 5–6 shorter genal setae. Antenna dark with arista whitish to ochrous, emerging at about middle of first flagellomere. Scape slightly bulbous, much longer than broad (length 0.145–0.15 mm, width 0.09 mm), setae about 0.05 mm. Pedicel slightly longer than scape, with several setae (longest dorsal seta 0.11 mm). First flagellomere very long, 0.26 mm, width 0.11 mm (holotype), apex seems “mutilated” in a number of specimens.
FIGURES 61–67. 61–66 = Poecilovitila elegans sp. n., male genitalia. 61 = surstylus, broadest inner (medial) view, 62 = ejaculatory apodeme, dorsal view, 63 = same, lateral view, 64 = pregonite, broadest extension, in a subventral-sublateral view, 65 = postgonite, broadest extension, in a sublateral view, 66 = phallapodeme, dorsal view. 67 = Poecilovitila barbata sp. n., 5th tarsomere with claws in ventral view (not complete). Scales: 0.2 mm for Figs 62–63, 0.1 mm for Figs 61, 64–67.
Thorax. In profile anterodorsal edge of mesonotum (to pronotum) is smaller than 90°. Mesonotum, scutellum and dorsal parts of pleuron pale brown; venter of pleuron dirty yellow to ochreous with transition gradual. Mesonotum granulose, scutellum rugose, both subshining.
Wing. Membrane mostly light brown, dark brown in cell r1 at edge and most apically, also entire cell r2+3 and upper part of r4+5 dark brown, excluding a narrow lighter diffuse part under R2+3 (Fig. 116). White spot two times longer than wide (0.187 long, 0.093 wide). Veins brown, darker on darker areas of membrane. Length of costal sections (all wing measurements in mm) between R1 and R2+3 1.31, between R2+3 and R4+5 0.91, between R4+5 and M1+2 0.40, no inter-crossvein section, costal seta 0.075, length of basal cell 0.25, length of discal cell 0.455, distance between apices of M veins 0.95 mm, cell r1 0.016 mm at narrowest, there vein R2+3 0.022–0.03 mm thick. Costal vein extending 0.055 mm past intersection with R4+5. Apical seta 0.075 mm. Vein M3+4 upcurved sub-basally, cell narrowed from 0.13 mm to 0.115 mm. Halter light brown, or knob dark brown.
Legs yellow with apex of femora brown.
Abdomen. Abdomen blackish with postabdomen yellow. Male tergite 1+2 large, 0.38 mm long or even longer.
Male terminalia (Figs 61–66, 122-123). Surstylus (Fig. 61) subquadrate, with inner wall only slightly longer than half length of outer wall. Surstylar pegs (26) ventral with 6 posteromedial. Phallapodeme (Fig. 66) medium large with base extending laterally as triangular processes. Pregonite (Fig. 64) with narrow, rounded apical extension, bearing some 14 thick but not particularly long setae. Postgonite (Fig. 65) comparatively wide with relatively broad, rounded apex. Ejaculatory apodeme (Fig. 62) with slightly broadened distal end, bent before midpoint.
Female. Abdominal sternite 8 as on Fig. 77. Spermathecae as on Fig. 81.
Etymology. The specific epithet reflects harmony in the shape and colour of the adult body.
