Distribution. Hungary, Romania (type locality: Mehadia, Romania).

Note. This species is new to the fauna of Hungary.

Description. Female. Frons reddish brown and getting darker to its dorsal margin. First flagellomere globose, reddish brown, with preapical arista. Palps yellowish, normal in size. Four supra-antennal setae present, the upper pair somewhat stronger. Antials at the same distance between the margin of frons and the median-sagittal furrow. Anterolaterals and mediolaterals close to eyes, preocellars a little bit more caudal than mediolaterals. All the characteristic setae same in size except supra-antennals, which are shorter ( Fig. 1 ).

Dorsal surface of thorax brownish. Mesopleuron bare. Scutellum with four setae, anterior pair 2/3 as long as posterior pair. Scutellum brownish fading to yellow at the margins. Wings typical for the genus. Haltere yellowish. Legs yellowish, hind femur apically with a brown patch. Fifth foretarsomere longer than the fourth ( Fig. 5 ). Fore metatarsus short and stout. No conspicuous sternites present, ventrally strong and dense setae emerge in “U”-shape in caudal direction ( Figs. 8–9 ). Ovipositor ( Fig. 10 ) shiny dark dorsally, its ventral parallel lobes are rounded apically.

Male. Schmitz (1919) made a detailed description on the male P. pictofasciata which is very similar to the female. To distinguish males of P. pictofasciata and P. spectabilis I described the male genitalia as follow: Epandrium high in lateral view, with caudal setulae ( Fig. 12 ). Anal tube dark, with microtrichia and with long setae only beyond its caudal end. Apical seta bare. Hypandrium relatively short, bilobed ( Fig. 14 ). The entire left and right lobe are covered in dense microtrichia and separated from each other by a bare field.
