Scape, pedicel and first flagellar segment yellow, other flagellar segments bicolor, yellowish with dark brown base. Scutellum and mediotergite dark yellow with dark gray mid-longitudinally. Prescutum dark yellow with four stripes, median stripes reddish brown, lateral stripes dark. Tergite 9 of male separated medially, with fleshy upper tergal lobes flattened, and two widened black sclerotized blades at a lower level. Etymology The species is named after the shape of blades of tergite 9, the Latin adjective ‘ platyphylla ’ refers to ‘having flat leaves’. Material examined Holotype CHINA • ♂ ; Tibet , Bomi , Tongmai (通麦); coordinates of the town: 30°06′00″ N , 95°04′56″ E ; 21 Aug. 2011 ; Lihua Wang leg.; light trap ; specific geographic coordinates and altitude not recorded; CAU .

Proboscis brown; palpus yellowish brown. THORAX ( Figs 66, 68 ). Mainly reddish yellow with dark yellow pruinescence. Pronotum reddish yellow with yellow setae. Prescutum dark yellow with four reddish brown stripes, median stripes broadened apically and gradually narrowing to base, lateral stripes long-oval, dark reddish brown. Scutum almost entirely brown with four olive-gray pruinose spots. Scutellum and mediotergite dark yellow with dark gray mid-longitudinally. Thoracic pleuron reddish yellow. Anepisternum pale brown.

ABDOMEN ( Figs 66, 68 ). Mainly yellow. Middle of abdominal tergites 1–2 with pale brown stripes, other tergites without spot. Abdominal segments 5–9 brown. Setae on abdomen yellow. HYPOPYGIUM ( Figs 69–73 ). Gonocoxite elongated, separated from sternite 9, gonocoxite ends with a sharp black upper spine, directed chiefly upward, bottom of gonocoxite also with a black upper spine ( Figs 69, 73 ). Posterior margin of membranous suture between tergite 9 and gonocoxite with a spiny projection. Tergite 9 separated medially, with fleshy upper tergal lobes flattened, two widened sclerotized blades at a lower level, apex of blade black and serrulate. Sternite 9 with a median prominence; apex of appendages of sternite 9 slender, basally dilated. Outer gonostylus slender, strip-shaped; stem almost without setae ( Fig. 71 ). Inner gonostylus with a subtriangular elevation, lower beak close to base of upper beak ( Fig. 72 ). Female Unknown or unrecognized. Distribution China ( Tibet ). Figs 66–68.

Remarks The new species is similar to T . ( V .) gandharva Alexander, 1951 from India ( Assam ) and Myanmar , but the latter differs in the following characters: dorsolateral extensions of tergite 9 long and slender, sclerotized ventral blades much less massive; the spine of gonocoxite is smaller than this new species.
