(Figs 1–10)
Description: Male. Body length 6.0 mm.
Head. Eyes covered with short and sparse ciliated; ommatidiae expanded on upper inner side; frons subequal to 1.5 times as wide as anterior ocellus; frontal vitta black, subequal to width of fronto-orbital plate, 7–8 frontal setae reaching to the front part of anterior ocellus, which the upper 3 ones rather short, upper orbital setae absent; fronto-orbital plate, parafacial and gena with grayish pruinosity, parafacial about 1.5 times as wide as 1st flagellomere; antennae black, slender, 1st flagellomere 2.5 times as long as wide, arista short plumose, the longest hair about 1/2 of 1st flagellomere in width; facial carina projected reaching to the anterior margin of lower facial margin; lower facial margin projected extremely, which become right angle with facial carina; vibrissal angle projecting over frontal angle obviously; genal height about 2/9 of eye height; genal and postgenal hairs all black; proboscis slender, rostrum longer than haustellum; prementum with gray pruinosity and thin hairs, 7 times as long as wide; palpi black and small, only 1/3 of width of prementum; labellum small.
Thorax. Black in ground color with blue-grayish pruinosity; scutum with 4 black vittae; scutellum black; acr 2+2, dc 2+3, ial 0+2, pra rather long, equal to 2.0 times of posterior postpronotal seta; notopleuron, the lower and flank of scutellum, basisternum of prosternum, meron and katepimeron all bare; the anterior spiracle yellow, the posterior one brown; katepisternal setae 1+2; wings slightly hyaline; veins brown; basicosta yellow; subcostal sclerite brown; costal spine short and small; radial node bare; R 4+5 and M veins slightly straight on apical part; the surrounding of r-m and dm-cu crossveins uncloud; calypteres brownish; halteres yellow; legs all yellow except dark on tarsuses; fore tibia with 1–2 medium p; mid femur with complete av and pv rows, which become longer hair-shaped apically, av 1 on preapical part, pd 2–3, mid tibia p 2; hind femur with a sparsely av row, pv 1–2 on medial part, hind tibia av 5, ad 2, pv 1 on apical fifth, without apical pv; the length of tarsuses longer than tibiae; the length of claws and pulvilli short and small.
Abdomen. Ovate-shaped, with blue-grayish pruinosity; tergites with ovate-shaped black patches, which latter parts joined with lateral patches become mountain-shaped patches; the latter marginal setae of tergites 4 and 5 slightly long and strong; sternite 1 bare.
Female. Body length 6.8–7.2 mm.
Ommatidiae not expanded; frons about 0.4 time as wide as head, frontal vitta about 3.0 times as wide as fronto-orbital plate, frontal setae 3–4, with a pair of orbital setae, outinclined; parafacial about 2.0 times of 1st flagellomere; genal height about 2/5 of eye height; acr 0+1; fore tibia with 1black medium p; mid femur without av row, with 5 slender pv on basal half; hind tibia ad 1; abdominal tergites with medium black vittae. Other characters same as the male.
Holotype: male, P. R. China: Tibet: Mt. Duoxiongla, 3600–4200 m, 8, VIII, 2003, Coll. Mingfu Wang.
Paratypes: 1 male, same data as holotype; 2 females, same data as holotype.
Etymology – The specific name is from the Latin words bacill- means stick, rostr- means proboscis, referring to rostrum longer than haustellum as well as prementum pole-shaped, 7 times as long as wide.
Remarks – This species belongs to Phaonia oxystoma -group, and resembles Phaonia hebetoida MA et DENG, 2002, but it differs from the latter in frons subequal to 1.5 times of width of anterior ocellus; parafacial about 1.5 times as wide as 1st flagellomere; genal height about 2/9 of eye height; palpi black and small, only 1/3 of width of prementum; the anterior spiracle yellow; hind femur with pv 1–2 on medial part.
