Diagnosis. The species is similar to Phaonia rufipalpis (Macquart, 1835)  with yellow palpus and antenna, long plumose arista, yellow postpronotal callus and reduced prealar seta. The new species can be distinguished as follows: eye bare, 3 dorsocentral setae, fronto-orbital plates of male separated by a frontal vitta, thorax with thick greyish-white dust, scutum of male without distinct longitudinal vittae, fore femur dark, tarsomeres brownishyellow, tarsomere 5 of all legs yellow, mid tibia with 2 posterior setae, abdomen dull yellow, with a dark median line and grey dust on tergites 4 and 5.

Etymology. The species name is a patronym in honour of the dipterist Nina P. Krivosheina  (Moscow), who collected the type series.

Type material examined: Holotype male, No. 17, Tajikistan, Tigrovaya Balka State Nature Reserve [37 º 15 'N 68 º 28 'E],?larva in an in leakage of Populus  sp., collected 11.v. 1987, emergence 1.vi. 1987, N. Krivosheina [ ZMUM]. Paratypes 7 females: same locality as holotype, No. 13, 27.iii. 1986 [emergence 16.iv. 1986], No. 21, 28.iii. 1986 [emergence 16.iv. 1986], No. 49, 4.iv. 1986 [emergence 28.iv. 1986], No. 50, 5.iv. 1986 [emergence 20.iv. 1986], No. 20, 12.v. 1987 [emergence 15.v. 1987], N. Krivosheina; No. 3, 6.iv. 1987 [emergence 4.v. 1987], A. Zaytsev; No. 81, 6.v. 1978, Abdurakhmanov. 1 male, No. 7, 13, Tajikistan, “Tatra Mts Range” [undecoded locality], Populus  sp.,? vii. 1979, Abdurakhmanov [ ZMUM].

Description. Male. Head: Ground-colour black. Eye bare. Fronto-orbital plates separated by a frontal vitta which is about as wide as width of postpedicel ( Fig. 7View FIGURE 7 B). Face, fronto-orbital plates and frontal vitta densely silvery pruinose, shining, face yellowish below. Occiput light grey. Fronto-orbital plates with 2 pairs of strong and 1 pair of short frontal setae only in lower half, upper half bare, without any setae ( Fig. 7View FIGURE 7 A). Distance between eyes equal to 2.2 times width of postpedicel. In lateral view, facial edge not projecting forward beyond the level of profrons. Antenna yellow; arista long plumose, longest aristal hairs longer then diameter of postpedicel. Postpedicel ca 3 times as long as wide. Parafacial at level of insertion of arista 1.3 times as wide as postpedicel, narrowing below. Genal depth below lowest eye-margin as broad as 1.5 times diameter of postpedicel. Palpus yellow.

Thorax: Ground-colour black with dense greyish-white dust. Scutum without distinct longitudinal vittae. Prosternum bare. Prealar seta inconspicuous, much shorter then posterior notopleural or absent. Dorsocentrals 2 + 3. Presutural acrostichals very short, much shorter than dorsocentrals but distinct, longer than the ground-setulae ( Fig. 7View FIGURE 7 A). Meron and katepimeron bare. Notopleuron without setulae. Postpronotal callus dull yellow ( Fig. 7View FIGURE 7 A). Katepisternal setae 1 + 2. Scutellum black, grey dusted, sometimes with a small dull yellow spot at apex around apical setae, entirely bare on underside.

Wing: Clear except for some clouding over crossveins r-m and dm-cu, white at base. Cross-vein dm-cu upright, almost straight, forming a right-angle with vein M. Basicosta and tegula yellowish-grey. Without costal spine. Radial node on lower side bare. Calypters white. Haltere yellow.

Legs: Yellow, except dark fore femur or all femora brownish-yellow (holotype). Coxae yellow. Tarsomeres brownish-yellow, tarsomere 5 of all legs yellow. Fore tibia with 0–1 posterior seta (holotype without ones). Mid tibia with only 2 posterior setae. Hind femur without elongated posteroventrals but with a row of short setae on posteroventral surface in basal half. Hind tibia without apical posteroventrals, with 2 anterodorsals, 1 anteroventral and 1 posterodorsal seta.

Abdomen: Oval, elongate; dull yellow, with a dark median line. Tergites 4 and 5 grey dusted ( Fig. 7View FIGURE 7 C). Sternite 5 as in figure 7 D.

Terminalia: Epandrium as wide as high; surstylus elongate, as long or longer than cerci in lateral view, bent medially with apex rounded ( Figs 8View FIGURE 8 A, B); cercal plate about as high as wide, square-shaped, without outer and inner ventral projections, with apex rectilinear in posterior view ( Fig. 8View FIGURE 8 C).

Measurements: Length of body, 4.2–5.3 mm. Length of wing, 4.2–5.3 mm.

Female differs from the male as follows:

Head: Dichoptic. Frons at middle 0.33 of head-width at this point, and at this point each fronto-orbital plate 0.35–0.4 of frontal vitta ( Fig. 9View FIGURE 9 B). Fronto-orbital plate with 2–3 pairs of frontal setae and 2 orbital setae ( Fig. 9View FIGURE 9 A).

Frons without cruciate interfrontals. Postpedicel black except yellow base, scape and pedicel brownish-yellow. Scutum with 2 dark indistinct longitudinal vittae, seen from behind. Dull yellow spot at apex of scutellum sometimes elongated along lower margin.

Abdomen: Densely grey dusted with a black median line, base of abdomen and lower margins of tergites yellowish.

Ovipositor: short with broad lateral tergal plates ( Figs 9View FIGURE 9 C, D).

Measurements: Length of body, 4.2–6.2 mm. Length of wing, 3.8–4.3 mm.
