(Figs 68–75, 115)
Type material. Holotype 3 (HNHM): VIETNAM: Sin Chai, “Legendary place”, 10. 11. 2003, No. 1, along forest path & creek, leg. Földvári, Peregovits, Kőrösi. Paratypes (HNHM): 1 Ƥ: same as for holotype; 1 Ƥ: ibid., Tram Ton, along and over a small stream, sweeping, Apr 9-11, 2010, VN 2010PL_5.
Description. Measurements in mm: body length 2.31 (holotype), 2.75 (paratype); wing length 2.81 (holotype), 3.80 (paratype); wing width 0.87 (holotype), 1.10 (paratype).
Head. Prefrons yellow, rather shining, much higher than its minimal width. Postfrons ochrous, shining, lightly convex. Gena comparatively broad, 0.10 mm below eye, oblique or almost vertical. Genal setae: one 0.21 mm long seta just below anterior edge of eye, a similarly long seta not much posteriorly, plus 4–5 medium-long genal setae. Antenna dark, arista whitish. Scape longer than broad (0.105 * 0.08 mm), with some setae, longest seta 0.05 mm. Pedicel shorter than scape, with apical and subapical setae, the longest dorsal seta 0.10 mm. First flagellomere much longer than high, 0.20 mm * 0.11 mm.
Thorax. Mesonotum and scutellum brown. Mesonotum rather smooth and shining, with fine microtrichia. Scutellum with fine transverse grooves. Dorsal ¾ of anepisternum and anepimeron brown, pleura yellowish ventrally.
Wing. Vein R2+3 rather much thickened medially, almost touching costa (Fig. 115). Wing membrane lighter brown, white spot slightly higher than semicircle, 0.137 mm long, 0.15 mm high. Dark brown membrane in cell r1 at edge of R1 and most apically, cell r2+3 almost entirely dark, except for the white spot and a diffuse lighter area below R2+3, upper part of r4+5 also dark, diffuse lighter spots in lower apical part of r4+5, in m cells and basally on wing. Veins brown, dark on darker membrane areas. Length of costal sections (all wing measurements in mm) between R1 and R2+3 1.39, between R2+3 and R4+5 0.70, between R4+5 and M1+2 0.51, inter-crossvein section 0.022, basal costal seta arcuate 0.17 mm, costal seta 0.10, length of basal cell 0.27, length of discal cell 0.43, distance between apices of M veins 0.83 mm, cell r1 0.008 mm at narrowest, where vein R2+3 0.028–0.03 mm thick. Costal vein continued on a section of 0.085 mm over the apex of R4+5. M3+4 strongly recurved sub-basally, cell narrowed from 0.10 mm to 0.08 mm there. Halter with knob dark brown, stalk lighter.
Legs yellow, but apices and dorsal half of femora diffusely light brown, 4th and 5th tarsomeres also darker, or even all fore tarsus dark (paratype).
Abdomen. Tergites unicolorous dark brown, membrane between tergies and sternites lighter, sternites yellow.
Male postabdomen. Syntergosternite very light, almost wholly transparent. Tergite 7 only 0.12 mm long dorsally. Sternite 6 somewhat larger than usual, 0.06 mm long. Subepandrial sclerite (Fig. 69) mostly membranous with better sclerotised rim. Male surstylus (Figs 67–68) of a characteristic shape, with 13 black teeth apically, some of them distant to each other. Six longer setae on ventral caudal edge. Long surstylar setae are somewhat more numerous than in P. barbata. Pregonite (Fig. 74) comparatively small with long ventral setae. Postgonites much incurved, almost meet sagittally, consequently their best view is the caudal one (Fig. 73). Epiphallus transparent, rounded. Phallus curved to the left completely. Mesophallus not longer than distiphallus, its right ribbon very thin, ribbons largely U-shaped. Apex of distiphallus without a curved process. Phallapodeme (Fig. 70) broad Y-shaped, rod rather long and narrow with broadened sital end, proximal part not particularly broad. Ejaculatory apodeme (Figs 71–72) with broadened distal apex, rather long but comparatively narrow basal part (“shovel end”), which bears a large less sclerotised bulb.
Female without peculiar characters.
Etymology. The specific epithet of this new species is a Latin word for a non-rugose surface, which is characteristic for the dorsal part of the mesonotum.
