Diagnosis. The species is similar to Phaonia boleticola (Rondani, 1866) with long plumose arista, reduced prealar seta, 3 dorsocentral setae, absence of long strong frontal setae in upper half, yellow legs, bare meron, katepimeron and notopleuron. The new species can be distinguished as follows: eye virtually bare (hairs very short), frontoorbital plates of male separated by a broad frontal vitta, which is as wide as diameter of postpedicel, antenna and palpus brownish, prealar seta short, half as long as posterior notopleural seta, scutellum dull yellow apically, abdomen greyish-white dusted, all tarsomeres brown, except yellow 5 tarsomere.
Etymology. The species name is based on the type-locality, Babarab village (Babaarap or Babarap in Turkmen) in Turkmenistan.
Type material examined: Holotype male, No. 102, Turkmenistan, Babarab [28 km NW Ashgabat, 38º05'N 58º06ºE], in Salix sp., 27.iv.1982, N. Krivosheina. Paratype female, No. 112, Turkmenistan, Babarab, in Ulmus sp., 29.iv.1982, N. Krivosheina [ZMUM].
Description. Male. Head: Ground-colour black. Eye virtually bare (hairs very short). Fronto-orbital plates separated by a frontal vitta which is about as wide as diameter of postpedicel (Fig. 1 B). Face, fronto-orbital plates, frontal vitta densely silvery pruinose, shining. Occiput light grey. Fronto-orbital plates with 5 pairs of strong frontal setae only in lower half, upper half bare, only with one pair of very short hairs (Fig. 1 A). Distance between eyes 3 times width of postpedicel. In lateral view, facial edge not projecting forward beyond the level of profrons. Antenna brownish; scape and pedicel brownish-yellow, postpedicel black except reddish base; arista long plumose, longest aristal hairs a little longer than diameter of postpedicel. Postpedicel ca 3 times as long as wide. Parafacial at level of insertion of arista 1.5 times as wide as postpedicel, little narrowing below. Genal depth 2 times width of postpedicel. Palpus brownish, darker at the tip.
Thorax: Ground-colour black with thick greyish-white dust. Scutum with 4 distinct dark longitudinal vittae, seen from behind (Fig. 1 C). Prosternum bare. Prealar seta short, half as long as posterior notopleural seta. Dorsocentrals 2+3. Presutural acrostichals strong, 3 pairs, half as long as first pair of dorsocentrals (Fig. 1 A). Meron and katepimeron bare. Notopleuron without setulae. Katepisternal setae 1+2. Scutellum dull yellow apically, 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 forming a right-angle with vein M but sinuous, S-shaped. Basicosta yellowish, tegula black. Without costal spine. Radial node on lower side bare. Calypters white. Haltere yellow.
Legs: Yellow, except fore femur dark in basal 3/4. Coxae grey. All tarsomeres brown, except yellow tarsomere 5. Fore tibia without posterior seta. Mid tibia with only 2 posterior setae. Hind femur without elongated posteroventrals but with 3 short setulae in middle on posteroventral surface. Hind tibia without apical posteroventrals, with 1–2 anterodorsals, 1–2 anteroventral seta and 1 posterodorsal seta.
Abdomen: Oval, elongate; greyish-white dusted, with a dark median line which is reduced on tergite 5 (Fig. 1 C). Sternite 5 as in figure 1D.
Terminalia: Epandrium about as wide as high; surstylus short and broad, bent medially with apex rectilinear in lateral view (Fig. 2 A); cercal plate about as high as wide, with outer ventral projection narrowed in apex, no longer than broad and blunt inner projection (Fig. 2 B).
Measurements: Length of body, 7.2 mm. Length of wing, 6.8 mm.
Female differs from the male as follows:
Head: Dichoptic. Frons at middle 0.26 of head-width at this point, and at this point each fronto-orbital plate 0.28 of frontal vitta. Fronto-orbital plate with 2 pairs of orbital setae and in addition to strong frontal setae with a row of short setulae reaching from orbital setae to aristal base. Frons with very short thin interfrontals. Face, fronto-orbital plates and frontal vitta densely greyish-yellow pruinose with a shifting silvery and grey dusted pattern. Palpus a little dilated, black in apical 2/3 and red at base (Fig. 1 E).
Thorax: Prealar seta a little shorter than posterior notopleural seta.
Legs: In general colour as in male. One hind leg and hind tibia absent.
Ovipositor: Not dissected.
Measurements: Length of body, 6.2 mm. Length of wing, 5.8 mm.
