Differential diagnosis
Thornburghiella salihi sp. nov. resembles T. erinacea (Krek, 1970) comb. nov. in body size, as well as wing shape. Thornburghiella erinacea is readily distinguishable by a scapus 2.4 times as long as the postpedicel. Flagellomere 1 (postpedicel) cucumber-shaped, straight, 3.2 times as long as the following flagellomere ( Krek 1970a: 89, fig. 5). Postpedicel with 8 conspicuous, strong bristles arranged in a row. Terminal flagellomere twice as long as the foregoing one, with a little prolonged digit in the axis ( Krek 1970a: 89, fig. 3). Gonostyli are with a conspicuous bulbous base ( Krek 1970a: 89, fig. 1, sic!) and bent. Distiphallus narrower in the middle; for details, see Krek (1970a: 89, figs 1–2).
Table 1 View Table 1 with a morphological comparison shows that Ulomyia erinacea and the new species suggest their belonging to Thornburghiella rather than to Ulomyia .
Etymology
This species is named in honour of Salih Krek (University of Sarajevo), a famous taxonomist and collector of Psychodidae in the area of the Balkan Peninsula.

Description
Male
HEAD. Hardly as long as broad. Vertex conspicuously conically inflated dorsally, forming a V-inverted sclerotized hood with a cut top. The numerous setae alveoli are spaced almost regularly over the entire surface of the upper half of head, with 3–4 supraocular bristles near dorsal margins of the eyes on the extreme lateral sides, despite scar-free striped areas above C-shaped compound eyes medially and laterally. Dorsolateral margins of the eyes are undulant. Eyes separated, interocular suture broadly V-shaped, more sclerotized basally, with a tongue-shaped inconspicuous ligament ( Figs 21 View Figs 21–34 , 35 View Fig 35–42 ); eye bridge formed by five facet rows; inner rows of the eyes are reduced to three facets. Minimum distance between eyes corresponds approximately to 2.4 facet diameters; index of distance from tangential points of eye apices to minimum of frons 3.2. Setae alveoli of the frontoclypeus arranged in an almost semicircular, centrally placed patch near the base of the antennae, tapering to a dorsoventral irregular strip of hairs close below the frontal suture ( Figs 21 View Figs 21–34 , 35 View Fig 35–42 ). Antenna with 16 articles; scape club-shaped, cylindrical ( Fig. 2 View Figs 1–8 ), somewhat widened apically, 2.7 times as long as its maximum width, narrowed at base, 6.0 times as long as its minimum width. Pedicel almost globular, symmetrical. Flagellomere 1 (postpedicel) pear-shaped, as long as the two following flagellomeres together ( Fig. 22 View Figs 21–34 ), or shorter ( Fig. 24 View Figs 21–34 , paratype Cat. No. 34955, Inv. No. 26012 from Loc. AZE 27), 1.3 times as long as the second flagellomere. Postpedicel with 3–6 conspicuous, strong bristles arranged in a row. Scape and pedicel with stiletto-shaped scales in contrast to needle-shaped macrosetae of flagellomeres. Flagellomeres 2–12 ovoid, with needle-shaped paired ascoids ( Fig. 22 View Figs 21–34 ), a little bent, shorter than the flagellomeres in which they are inserted; apical pear-shaped flagellomere a little longer than the previous one ( Fig. 23 View Figs 21–34 ), sometimes the last flagellomeres are fused with a long apiculus in the longitudinal axis ( Fig. 25 View Figs 21–34 , paratype Cat. No. 34956, Inv. No. 26013 from Loc. AZE 27). Length ratio of maxillary palp segments 1.0:1.3:1.4:1.6; apical segment annulated ( Fig. 26 View Figs 21–34 ). Terminal labial lobes ( Fig. 36 View Fig 35–42 ) with diverging rows of spines between them, tongue distal protuberances are inconspicuous. Ratio of maximum length of cibarium ( Fig. 37 View Fig 35–42 ) to length of epipharynx approximately 1.4:1.
THORAX. Anepisternum setae patch almost semicircular between spiracle and wing insertion ( Fig. 27 View Figs 21–34 ), anepimeron with a striped setae patch. Spiracles set high on the mesothorax. Patagium not developed. Wings ( Fig. 38 View Fig 35–42 ) lanceolate, 2.7 mm in holotype, 2.4–3.1 mm in paratypes, rounded distally, a little expanded at the posterior margin. Ending of R 5 is beyond the tip of the wing. Wing membrane slightly infuscated only between Sc, R 1 and C. The following veins or their parts strengthened: Sc with conspicuously marked origin and end, R 1 (not the start), R 2, R 5, basal field, CuA 1 (conspicuously basally) and CuA 2. Radial fork complete in contrast to medial one. Both forks and the ending of CuA 2 are in one line (almost central area of wing). Wing index 2.5. Bases of M 3, CuA 1 and CuA 2 are not connected. Knob of halteres hardly globular, a little cut apically, with close sensory microsetae subapically, a prolonged stem as usually developed ( Fig. 28 View Figs 21–34 ). Ratio of maximum length of halteres to their maximum width approximately 2.5:1. Ratios of lengths of femora, tibiae and first tarsal segments P 1 2.2:2.4:1.0, P 2 2.4:2.8:1.2, P 3 2.6:3.4:1.3. Paired tarsal claws of P 1 almost straight, gradually tapering, hooked only subapically ( Fig. 29 View Figs 21–34 ).
MALE GENITALIA. Basiphallus almost straight from dorsal view ( Figs 31 View Figs 21–34 , 41 View Fig 35–42 ), only sometimes strangulated proximally ( Fig. 33 View Figs 21–34 ), a little undulated from lateral view ( Fig. 42 View Fig 35–42 ). Spatula at the base of aedeagal complex shortly bilobed ( Figs 31 View Figs 21–34 , 41 View Fig 35–42 ), distiphallus keg-shaped, prolonged, with inner pipe bordered by indefinable parallel folds and a telescopic gonoporus strengthened by sclerotized, distally connected rounded folds ( Figs 31, 34 View Figs 21–34 , 41–42 View Fig 35–42 ). Gonocoxites almost cylindrical, without bulbose base ( Figs 31–32 View Figs 21–34 , 40 View Fig 35–42 ), as long as the gonostyli. Epandrium ( Figs 30 View Figs 21–34 , 39 View Fig 35–42 ) rectangular, with two divided areas of insertions of hairs distally). Basal paired apertures conspicuous, mostly separated with irregular margins; however, may be connected in a single oval aperture, see paratype from the site Loc. AZE 27, Cat. No. 34955, Inv. No. 26012 (only one male). Ventral epandrial plate not developed ( Figs 30 View Figs 21–34 , 39 View Fig 35–42 ). Hypandrium narrow without a lobulus in the middle ( Figs 31 View Figs 21–34 , 41 View Fig 35–42 ). Epiproct inconspicuous, triangular, covered with microsetae; hypoproct conspicuous, tongue-shaped, setose, rounded apically from dorsal view ( Figs 30 View Figs 21–34 , 39 View Fig 35–42 ), 1.1 times as long as the epandrium. Epandrial appendages strong, cylindrical and straight from dorsal view, enlarged a little basally in contrast to the top ( Fig. 39 View Fig 35–42 ), bent from lateral view ( Fig. 30 View Figs 21–34 ). Tenacula (numbers 9–12) restricted to a cluster near the rounded apex and gradually becoming shorter towards apex of the epandrial appendages ( Figs 30 View Figs 21–34 , 39 View Fig 35–42 ).
Female
Unknown.
Comments
Krek´s Sijaricia (as subgenus) must be synonymized with Thornburghiella because T. erinacea was established by him as type species (monotypy) of the genus Ulomyia .
Bionomics
Unknown; males were collected near montane waterfalls and streams or confluences of rivers, approximately 1200–1600 m a.s.l.
Distribution
Currently recorded only from Georgia and Azerbaijan.
