(Figs 48–55, 114)
Type material. Holotype 3 (HNHM): VIETNAM: Lao Cai Prov., Sín Chai, Hoáng Liên N.P., Tram Ton, along and over a rivulet, 1936 m, 22º20.941’N 103º46.197’E, Dec 16–17, 2008, leg. L. Papp, VN 2008PL10. Paratype (HNHM): 1 3: same as for holotype [genitalia of the paratype male in a plastic microvial with glycerol].
Description. Measurements in mm: body length 2.18 (holotype), 2.15 (paratype); wing length 3.01 (holotype), 2.98 (paratype); wing width 1.12 (holotype), 1.01 (paratype).
Head less flattened than in P. thaii. Prefrons (facial plate) narrow, higher than its minimal width: 0.28 mm high, 0.16 mm broad there, slightly greyish yellow. Frons shining, slightly brown, its microtrichia seem slightly longer than those of P. defecta; frons with transverse shallow broad impression between bases of fronto-orbital setae. Gena very narrow, only 0.06 mm broad, horizontal, dirty yellow, covered by dense white microtrichia. Genal setae: anterior seta 0.225 mm long, other 4 shorter genal setae behind, not on mouth edge. Scape bulbous, longer than broad, 0.105 x 0.06 mm, longest dorsal setae 0.08 mm. Pedicel 0.06 mm long, longest dorsal seta 0.105 mm long. First flagellomere dark blackish brown, dorsally 0.27 mm long. Arista whitish.
Thorax. Mesonotum flattened dorsally, anterior (postcephalic) margin terminates in a perpendicular hump, similarly to P. defecta, i.e. angle in profile not sharp as in P. defecta. Mesonotum and scutellum deeply rugose and granulose, and mesonotum with a pair of interdorsocentral fossae; fossae less dark and inside them granulosity is finer. Pleuron yellow with with almost all of anepisternum and anepimeron dark brown.
Wing. Membrane light brown with a dark apical spot in cell r1, membrane dark around white spot down (diameter of 0.15 mm) to costal apex in cell r2+3 (except its proximal upper part below R2+3) and in cell r4+5 (Fig. 114). Diffuse darker spots basally, at apical part of r2+3 and 2 such spots in m cells. Veins brown, darker on darker areas of membrane. Length of costal sections (all wing measurements in mm) between R1 and R2+3 1.40, between R2+3 and R4+5 0.89, between R4+5 and M1+2 0.43, inter-crossvein section indistinct, practically not extant, costal seta 0.11, length of basal cell 0.23, length of discal cell 0.47, distance between apices of M vein 0.89 mm. R2+3 nearly reaching costa, cell r1 less than 0.01 mm at narrowest, there vein R2+3 0.033 mm thick. Costal vein continued on a section of 0.038 mm over the apex of R4+5. Apical seta 0.077 mm only. M3+4 strongly recurved sub-basally, M1+2 strongly downcurved apically. Halter with stalk light brown, knob dark brown.
Legs mostly yellow but apical 1/3 of fore femur and c. apical 1/6 of mid and hind femora brown, and base of tibiae diffusely brown.
Abdomen all dark. Second tergite much narrower than third. Male abdominal sternite 6 transverse, with sparse setae. Tergal setae short, with longer lateral-marginal setae 0.12 mm only. Lateral sclerites just anterior to epandrium (within the ring of synsclerite 7) distinct. Cerci short triangular with long setae (Fig. 55). Subepandrial sclerite rather small. Hypandrium short (Fig. 50). Surstylus (Figs 52–53) comparatively short and broad. Medial apical edge of male surstylus (Fig. 55) arcuate, with 14 closely set blunt black pegs (Figs 52–53). Pregonite (Fig. 50) subquadrate in lateral view with at least 7 long setae. Postgonite (Figs 50, 54) looks rounded apically in lateral view, although only a small apical part is lateroclinate. Epiphallus (Fig. 54) comparatively short and broad. Phallapodeme (Fig. 51) broad basally, and with rod comparatively long and thin. Ejaculatory apodeme (Figs 48–49) with comparatively long but not broad distal part, duct short. Mesophallus shorter than distiphallus, the latter large black compact, without apical process.
Etymology. The specific epithet of this new species refers to its bulbous scape.
