Examined material. 1♂ (DNA CK815, LT671783 , tips of surstyli damaged after ID), loc. 10, 11–13.v.2013 (SMTD); 1♂ 1♀ (DNA CK853, LT671784 ), loc. 7, 6–16.v.2013 (SMTD).

Remarks. This species was described on the basis of the male holotype from Kazakhstan and is phylogenetically and morphologically closely related to T. gazliensis Kuznetzov , which was previously recorded from Alborz province by Kehlmaier & Majnon-Jahromi (2015). Both species share an almost identical DNA barcode (compare to LK391742 ), differing by a single nucleotide position. Kuznetzov (1994) illustrated the male genitalia of both species only in lateral view. Despite certain haziness, the presented microphotographs of the epandrium and surstyli of T. urdaensis and T. gazliensis provide better evidence than line drawings for showing the subtle differences separating these two species: T. urdaensis has the basis of surstyli slightly broader and more angulate than T. gazliensis ; the surstyli of T. urdaensis have the outer lateral margins slightly more concave than T. gazliensis , and the apices more pointed ( Figs 19–20 ). However, the status of these species must be regarded as uncertain until larger series of specimens are available for study. We assume that the recorded female represents T. urdaensis as it was collected together with a male and shares its DNA barcode. The female of T. urdaensis is characterised as follows: flagellum tawny brown with yellowish apex; wing length 2.2 mm; third costal section half the length of fourth costal section; cross-vein r-m reaching cell dm in its middle; leg dark brown except for the yellow apex of femur, basal 1/4 and apex of tibia and tarsal segments (except distitarus); tergite 9 dark yellow, long and straight ( Figs 11, 14 ).
