BFF28901CF5653939BCF41D24D443143.taxon	etymology	Etymology. The name is dedicated to our colleague Jaroslav Stary and his life jubilee. (Jaroslav discovered the holotype of new species in his own material and provided it for the description).	en	Dvorak, Libor, Fogasova, Katarina, Obona, Jozef, Toeroek, Edina, Manko, Peter (2023): Two new Ptychoptera Meigen, 1803 (Diptera, Ptychopteridae) from the Western Palaearctic.

4ABF56F3B29C529A85B5F704180E8F15.taxon	description	Description. Male. Head: Frons, vertex, and occiput black with metallic blue shine, mouthparts including palpi pale yellow, scape and pedicel yellowish orange, antennal flagellomeres a somewhat darker, tending to pale brown. Thorax: Scutum, paratergite, and mediotergite blackish with metallic blue shine; scutellum, pleurotergite, katepisternum, and katepimeron brownish black with lighter metallic blue shine; other parts yellow. Halteres yellow with light brown knob. Legs yellow except brown extreme apex of femora and tibiae, tarsi somewhat darkened. Wing length 10 mm (holotype, Fig. 1 c). Wing almost hyaline, veins yellowish brown, distinct spots brownish black, forming more or less three stripes, at base of wing at the level of crossvein h, from C to Cu. Middle stripe touching vein C, running through cross-veins up to middle part of vein Cu, isolated spot before end of vein Cu. Isolated spot on around middle of R 1. Third stripe consist of three large, almost touching spots: at the tip of R 1 and fork of R 2 + 3, one on fork vein R 4 + 5 and one on fork vein M 1 + 2. Small spot at the end of vein R 3. Abdomen: Tergum 1 dark shiny brown with yellow apex, sternum 1 yellow. Tergum 2 brown basally and apically, yellow in middle, sternum 2 yellow. Tergum 3 yellow basally, brown apically, sternum 3 yellow. Remaining terga and sterna brown, sternum 4 yellow basally. Auxiliar copulatory organ yellow. Male genitalia (Fig. 2): Hypopygium almost 2 x as wide as long, widest in basal quarter, medially with very deep emargination. Epandrial claspers simple and long (length / width ratio ca. 5.8) and covered by long pale hairs, the longest hair up to 1.75 longer than width of epandrium. Apical stylus of gonostylus robust and rounded apically, secondary lobe long, reaching almost 0.75 of apical stylus length. Media lobe of basal lobe of gonostylus long and sharply pointed (saber-like); anterior lobe of basal lobe of gonostylus bulbous apically with several setae at extreme apex. Female. The authors have an immature female which was sampled in Lesser Caucasus (Georgia, Kakheti region, Ilto river, above (N of) the Chart'ala village, 790 m a. s. l., 42 ° 8 ' 18 " N, 45 ° 7 ' 32 " E, 8. VII. 2019, leg. P. Manko & G. Vincon). The characters correspond to the above-described new species. However, its identity cannot be confirmed in this stage of ontogenesis / development and could be solved after collecting more specimens of the genus Ptychoptera from the Transcaucasia.	en	Dvorak, Libor, Fogasova, Katarina, Obona, Jozef, Toeroek, Edina, Manko, Peter (2023): Two new Ptychoptera Meigen, 1803 (Diptera, Ptychopteridae) from the Western Palaearctic.
