Differential diagnosis: Similar to X. orthogona ( Rohdendorf, 1925) in the abdominal pattern and presence of black setae on gena, distinctly differing by the poorly differentiated, almost lacking lateral spots of 3 rd and 4 th abdominal tergites.

B o d y l e n g t h 5.0– 5.5 mm. M a l e. — Head yellow pollinose, frontal vitta yellow, slightly pollinose, vertex darker, antenna and palp yellow, apex of arista blackish. Frons at vertex 0.43×, at level of antennal base 0.33× head-width. Frontal vitta 2.2× widened backwards, in the middle of frons 2.0× as wide as one of parafrontalia. Postpedicel 0.5× as long as pedicel, arista widened almost to apex. Parafacialia at level of antennal base 0.17×, gena 0.08× eyeheight. Palp long, at apex strongly widened. oc long and strong; fr 9–10, medium long; orb 1+1, strong; parafrontalia and parafacialia with microscopic light setae; gena covered with black setae, in hind parts with mixed yellow and black setae; instead of vi, other oral setae absent. — Thorax covered with black medium long setae, densely grey pollinose, medial longitudinal stripes of tergites linear, apex of scutellum yellowish brown. acr 0+1, dc 0+1; ia 1+1; pprn 2; npl 2 (without setulae). Scutellum with 3 pairs of strong marg and one pair of crossed ds. — Wings are not preserved. — Legs almost entirely yellow, only middle part of fore femora grey pollinose. t 2 with one ad. — Abdomen densely light orange yellow pollinose, with very narrow black longitudinal median line on 1+2 nd — 5 th tergites. 5 th tergite in hind 1/3 with a pair of lateral small rounded shining brownish black spots, 3 rd and 4 th tergites with remains of similar spots. Terminalia small, brownish yellow, light pollinose.

Female. — Head. Frons at vertex 0.38×, at level of antennal base 0.28× head-width; genal black setae distinctly smaller than in {. — Wings hyaline. Costal spine absent, cell r 4+5 petiolate, M -vein acute-angled, R 4+5 bare, dm-cu s -like curved. — Legs yellow, only hind tarsi and apex of hind tibia fuscous. — Abdomen orange yellow, slightly light pollinose. 4 th tergite in hind 0.5 with rounded dark brown median spot, 5 th tergite with similar spot in hind 2/3 and with the remains of yellowish lateral stripes.

Etymology: The species is named in honor of the well known British entomologist, Mr Adrian C. Pont (Oxford University Museum of Natural History).
