Type specimen: Holotype male, China: Shanxi: Kelan County, 2000 m, 17.vii.1988, Coll.

M.F. Wang.

Diagnosis: This species is characterized as follows: antennal first flagellomere about 1.5X longer than wide, frons broad, the median part as wide as the distance between two posterior ocelli; pra 2, calypters yellowish; hind tibia with 2–4 ad and 1–2 av, hind femur with pv row.

Description: Male: Body length 5.0 mm. Eye with sparse and short hairs, nearly bare; the median part of frons as wide as the distance between two posterior ocelli, slightly narrower than antennal first flagellomere, frontal vitta linear in upper half, yellowish brown in lower half, with golden pruinosity, frontal setae 10–11, reaching ocellar triangle, upper orbital setae absent; parafacial and genal groove brown, parafacial bare, the median part 3/5 of the width of antennal first flagellomere; antenna black, first flagellomere 1.5X longer than wide, arista ciliated, the longest hair shorter than the width of aristal base; epistoma not projecting to vibrissal angle, vibrissal angle behind frontal angle in profile; gena and postcranium with black hairs, genal height about 1/10 of eye height; proboscis short, prementum with thinly yellowish gray pruinosity, 2.0X longer than wide; palpus black, cylindrical, slightly longer than prementum. Thorax ground­colour black, notum with thinly greyish pruinosity, slightly shiny; presutural acr biserial, slightly stout, the distance between two acr rows narrower than the distance between acr row and dc row, dc 2+3, pra 2, the anterior one stout, about 2/3 of the length of posterior notopleural seta, notopleural setae 2; ventral surface and lateral margin of scutellum bare; basisternum, proepisternum, anepimeron, meron and katepimeron bare; katepisternal bristles 1:1, katepisternum without ventral spines; proepimeral seta 1, accompanied by 10 slender and longish setulae, spiracles brown, posterior one large; calypters yellowish, the lower one with a linear structure. Wing brownish, wing­base yellow; tegula dark brown; basicosta brownish yellow; costal spine inconspicuous; vein C with a row of small spines on dorsal surface, vein Sc not curving bow­like; node of Rs bare on ventral and dorsal surfaces; veins R 4+5 and M straight; crossveins without obvious cloud; haltere brownish yellow. Legs entirely black; fore femur with numerous long setae rows on av, a and ad surfaces, fore tibia without median p, only with 1 stout apical d and 1 stout apical v, fore first tarsomere with 1 or 2 basal setae on ventral surface; mid coxa without any hooked spines or spine­like setae on lower and outer margins; mid femur with complete av row, towards apex gradually becoming shorter, ad row complete, pv row complete, from base to apex becoming pectinate rows, slightly biserial in median part; mid tibia slightly swollen in distal half, with 3 ad, 2 pd and numerous pappose hairs on ventral surface in distal half, the longest seta about equal to or slightly longer than the width of mid tibia, mid first tarsomere without basal tooth­like spines and only with biserial erected short spinal rows on ventral surface; hind coxa bare on posterior surface; hind femur with complete av row, sparse and long, 1–2 apical setae stout, a row complete, conspicuous pv row on basal 2/3, the longest one about equal to or slightly longer than the width of hind femur, hind tibia with 2 av, 3–4 ad, 1 submedian d, and 1 apical d. Abdomen long, depressed and flattened, ground color black, with thinly gray pollinosity, each tergite with long setae on lateral margins, tergites 2 and 3 with median triangular marks, tergite 5 only with 1 narrow median stripe; sternite 1 bare, sternites 2 to 4 with long setae, sternite 5 nearly as broad as long, moderately indented apically, the setae scattered evenly over the surface, none strikingly developed; cerci in posterior view cupuliform, tapering toward apex, the apex bifurcate and curving ventrally, without protuberance; surstyli in lateral view broadened, ventral margin deeply excavated in distal part, not separated into two branches.

Female: Unknown.

Remarks: This new species resembles Fannia tripla but differs from it in having hind femur with conspicuous pv row on basal 2/3; antennal first flagellomere 1.5X longer than wide, frons as wide as the distance between two posterior ocelli, calypters yellowish, and hind tibia with 3– 4 ad.

Distribution: P. R. China: Xizang Autonomous Region.

The holotype and only known specimen of this species is deposited in the Institute of Entomology, Shenyang Normal University, Shenyang, Liaoning Province, China.

Distribution: China: Shanxi.
