Body length: 6.5 mm. 
 MALE: HEAD. Head compressed anteriorly. Eyes separated by a distance 0.5 times as wide as ocellar triangle. Fronto­orbital plate black; greyish yellow pruinose; 7­8 rows of hairs laterally (not reaching to eyes). Frontal vitta black, pruinose. Frontal vitta at base of antennae 0.9 times as wide as fronto­orbital plate anteriorly. Ocellar setae present but fine; outer vertical setae present (hair­like); inner vertical setae absent. Face black with grey pruinosity. Parafacial brown to black, grey or yellow pruinose, haired (on upper part), 2 times as wide as first flagellomere. Lower margin of face projecting, visible in profile, orange yellow or brown, grey pruinose. Vibrissa well differentiated; intervibrissal distance 0.9­1.0 times distance between vibrissa and eye on same side; facial ridge with bristles on lower 2/5. Gena brown to black with grey pruinosity; hairs white; height 0.14 times eye height. Lunule black and shining; sublunular bulla indistinct. Antenna black; first flagellomere 1.2 times as long as pedicel; arista thickened on basal 0.2. Length of oral opening 2.1 times its width. Occiput flattened, white pruinose; hairs white and black. Palpus yellow. 
 THORAX. Mesoscutum thinly pruinose (brown), without black longitudinal vitta, with fine black hairs. 0+1 acrostichal seta; 0+1 dorsocentral seta; 2 postpronotal setae; presutural supra­alar seta present, strong; 1 postsutural intra­alar seta; 2 notopleural setae; 1 supra­alar seta; 2 postalar setae. Pleuron thinly grey pruinose; hairs black, white and yellow; and without scale­like setae. Anepimeral setae strongly; black. 1 katepisternal seta. 7­ 9 meral setae. Scutellum black; brownish grey pruinose, with two pairs of marginal setae; apical setae present and distinct; discal setae randomly arranged, not in rows. Subscutellum not very prominent. WING. Lower calypter brown to black. Wing base without scalelike setae. Tegula black. Basicosta yellow. Wing pictured, white with light brown infuscation, narrow; petiole of apical cell 0.16­0.18 times as long as preceding section of R 4+5; M meeting R 4+5 at acute angle. Halter brown. LEGS. Fore femur black; hairs black. Fore tibia black, without bristles, apically with 1 p and 1 d. Fore tarus black. Fore claws brown, apex black, 1.2 times as long as fifth tarsomere. Pulvilli brown. Mid femur black; hairs black. Mid tibia black, with 1 v, apically with 1 ad, 1 a, 1 av, 1 pv, 1 v and 1 d. Hind femur black; hairs black; scale­like setae absent. Hind tibia black, with 5­6 pd and 4­ 5 ad. 
 ABDOMEN. Abdominal tergites black; pruinosity brownish yellow; longitudinal vitta absent. Relative length of abdominal tergites I+II:III:IV:V = 1.4:1:1:1.2; relative width I+II:III:IV:V = 0.5:1:1:0.8. Hair spots indistinct. TERMINALIA. Syncercus slender, with a notch posteriorly. Surstylus longer than cercus, strongly arched dorsally. Ejaculatory apodeme small, knob­like. Hypandrium shorter than phallapodeme. Pregonite as long as postgonite, haired dorsally. Postgonite pointed. Phallus broad, slightly longer than phallapodeme, without hairs dorsally. Dorsolateral process membranous; ventrolateral process well sclerotized, strongly bent ventrally. 
 FEMALE. Wing hyaline. Eyes separated by a distance as wide as single ocellus, not touching. Anterior spine­like setae of hind tibia absent. Sternite VII (sheath) longer than sternite VI, plate­like, broad apically, bent, apex directed ventrally, almost smooth ventrally. Ovipositor bent downward. HOST 
Unknown. ETYMOLOGY 
This specific name is a patronym in honour S. Kudo, who collected the type material. NOTES 
 It is very difficult to separate females of P. kudoi and P. aurulans, but the male of Phasia kudoi Sun differs from Phasia aurulans Meigen in lacking a distinct golden yellow pruinose spot on the mesonotum, and in characters of the terminalia.
