Diagnosis. This species is similar to T. zaitzevi sp. nov. in having parafacialium twice as wide as antennal groove, three times as wide as flagellomere 1, but differs by long postero-dorsal extension of cell bcu (twice as long as width of the cell at its middle), and by mesonotum and postpronotum non-microtrichose. Cercal unit of the aculeus with one pair of long setae ( T. zaitzevi sp. nov. with two pairs of long setae on the cercal unit). Surstylus with a big rounded posteromedial lobe (in T. zaitzevi sp. nov., with gently sloping posteromedial lobe).

Description of the lectotype. Female: Head. Frons whole yellow, without microtrichose areas. Frons with dents and bumps, evenly covered with short and thin black setulae. Ocellar triangle shining black. Lateral parts of vertex entirely yellow without dark markings. Occiput yellow, covered with short and thin black setulae. Median occipital sclerite yellow, lateral occipital sclerite yellow, with thin silver-white microtrichosity close to eye margins. Gena yellow, 0.5 times as high as eye. Postgena yellow. Parafacialium yellow, wide, twice as wide as antennal groove, three times as wide as flagellomere 1, short and thin black setulose. Eye 1.7 times as high as wide. Lunula yellow. Face yellow, without darkened band along the lower edge. Clypeus yellow. Scape and pedicel orange-yellow. Flagellomere 1 orange. Arista pale brown. Antennal grooves yellow, with thin silver-white microtrichosity.

Proboscis yellow at its base, brown at apex. Palpus yellow, pale brown at apex. Setae (taxonomically significant setae are very short and about 1.2 times as long as other setulae, covering head). 6 small orb (first orbital seta a little longer than other ones), 1 divergent oc, 1 divergent poc, 1 divergent m vt, 10 divergent pocl, 1 short pa vt and 1 convergent i vt. 10 gn, 6 pgn setulae, 1 long gn seta. 2 groups of spc setae over occipital foramen.

Thorax. Yellow, with brown lateral spots (mainly on presutural area of scutum) and median strip. Mesonotum and postpronotum shining, without microtrichium. Scutellum subshining yellow, faintly sculptured, with short black setulae over its upper surface. Mediotergite yellow, with brown spot at middle. Pleura shining yellow. Anepisternum slightly microtrichose at its posterior margin. Katepisternum with brown spot in ventral portion. Setae. 1 short pprn, 2 npl, 1 spal, 1 prsc dc, 1 pal, 1 ial seta; 2 pairs of sctl, anepm setae absent; 1 anepst, 1 kepst seta, also anepisternum and katepisternum covered with short black setulae.

Legs. Entirely yellow. Tarsus (except first tarsomere) pale brown.

Wings. Hyaline, with yellowish apex and costal margin. Section of costal vein between R4+5 and M apices at wing apex as long as R-M crossvein. Posteroapical extension of cell bcu 2 times as long as width of the cell at its middle. Halter yellow.

Abdomen evenly short and thin black setulose. All tergites laterally yellow, brown at middle. Sternites yellow.

Female terminalia: Oviscape yellow. Aculeus eight times as long as wide at its middle, with two rows of short setae at each side. Cercal unit elongate oval, with 1 pair of long basal setulae. 3 spherical spermathecae with smoothed cellular surface and inverted necks; two left with T-shape bifurcated common duct.

Body length 8.5–11.0 mm. Wing length 7.0–9.0 mm.

Male: similar to female, except genital structures. Male genitalia. Surstylus with mesoventrally curved anteroventral lobe and with short posteromedial lobe covered with setulae on its ventral side. Cerci separated, each with obtuse angulate apex, covered with long setulae. Phallus with one short serrate basal caecum and one wide bare apical caecum. Glans with 3 short hooks and two membranous lobes.

Body length 8.0–10.0 mm. Wing length 6.0–8.0 mm.

Remarks. Variability was observed in coloration of frons among examined specimens: frons above lunula sometimes with pair of short light brown stripes; number of setae: 6–8 small orb, 10–14 divergent pocl, 10–12 gn, 4–6 long pgn setae; microtrichosity on anepisternum sometimes almost indistinguishable; tarsus sometimes entirely yellow.

Distribution. North China, Kazakhstan, Uzbekistan, Tajikistan, Kyrgyzstan, Turkmenistan.
