Face black with grey pruinosity. Parafacial brown; grey pruinose, almost bare, 2.2 times as wide as first flagellomere. Lower margin of face projecting, visible in profile, orange yellow, grey pruinose. Vibrissa well differentiated; intervibrissal distance 0.9­1 times distance between vibrissa and eye on same side; facial ridge with bristles on lower 2/5. Gena brown, grey pruinose, with a yellow spot; hairs white; height 0.18 times eye height. Lunule black and shining; sublunular bulla indistinct.

Lower calypter white with light brown infuscation. Wing base without scale­like setae. Tegula black. Basicosta black. Wing pictured; white with light brown infuscation, broad; petiole of apical cell 0.18­0.2 times as long as preceding section of R 4+5; M meeting R 4+5 at acute angle. Halter brown. LEGS. Fore femur black; ventrally and laterally with whitish yellow hairs, dorsal surface with black hairs. Fore tibia black, with 1­2 p, apically with 1 p and 1 d. Fore tarus black. Fore claws black; 1.2 times as long as fifth tarsomere. Pulvilli black. Mid femur black, mixed with whitish yellow and black hairs.

 ABDOMEN. Abdominal tergites with yellow spot or area (with a black median longitudinal vitta); pruinosity 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 of tergites IV, V indistinct. TERMINALIA. Syncercus broad, shallowly notched posteriorly; apex bent ventrally and hook­like. Surstylus straight, slender, slightly broadened apically, longer than cercus. Ejaculatory apodeme long, hook­like. Hypandrium as long as phallapodeme. Pregonite triangular, with a tooth ventrally. Epiphallus well developed. Postgonite slender, branched apically, haired ventrally. Phallus longer than hypandrium, dense hair dorsally. Dorsolateral process short, straight. Ventrolateral process long, strongly bent dorsally. 
 FEMALE. Body size smaller than male. Wing hyaline. Eyes separated by a distance 0.5 times as wide as ocellar triangle, not touching. Anterior spine­like setae of hind tibia present. Abdomen black, thinly grey pruinose. Sternite VII (sheath) longer than sternite VI, broad posteriorly; two posterior angles bent down into triangles; sternite VII with linear wrinkles ventrally. Ovipositor extremely long, almost straight. HOST 
Unknown. ETYMOLOGY 
 The name Phasia japanensis reflects the apparent restriction of this species to Japan. NOTES 
 Two specimens housed in the Institute of Zoology, Academic Sciences of Poland, Warsawa, labelled as " Alophora kagensis Takano " are assigned as paratypes of Phasia japanensis Sun, sp. nov.
