Diagnosis. This large species (Figs 27A, B) is characterized by proportionally long fore wings, and particularly by evenly robust and very long styles (Figs 28G, H) with hook-shaped apex. The aedeagus (Figs 28A, B) is smooth and very long, its socle in lateral view high, in ventral view very widely protruding laterally, with angular restriction at mid-length and rounded prominent distal angles. The connective (Fig. 2I) is long with branched part longer than basal one, branched portion basally very robust, apicad abruptly narrowing. Genital plates (Figs 29A, B) long, with lateral margin slightly sinuate, apex rounded, median margin of dorsal side basally with wide fold. From D. kusnezovi Vilbaste, 1961 and D. rikele Guglielmino & Bückle, 2021, which have a robust style morphology as well, the species is distinguished by a different shape of genital plates and major body size, from D. kusnezovi also by the hook-shaped apex of the styles, and from D. rikele by a quite different aedeagus shape. The hind margin of the female pregenital sternite (Fig. 20I) displays a distinct caudal median notch, in specimens from Europe split-shaped, in specimens from Uzbekistan narrowly rounded (see also Dlabola, 1961). The ovipositor is long, with the 2 nd valvulae (Fig. 4E) provided with about 28 teeth.

Fifth instar (Fig. 25C). Light brown without distinct markings; sagittal line on abdomen lighter; vertex with indistinct brown spots; generally, beneath base of antenna dark brown spot, and on ventrad folded lateral part of pronotum dark brown stripe.

Distribution (Fig. 60A). We studied material from Albania, Bulgaria, Greece, Hungary, Moldova, Romania, Serbia, and Uzbekistan. In addition, there are records for Austria (Holzinger, 2009); Russia: European part (Emeljanov, 1964); Turkey: European part (Nast, 1987) and Anatolia (Kalkandelen, 1974); Ukraine (Nast, 1987).

The species is recorded by Servadei (1967) in Italy only from Calabria. We studied all the specimens in his collection assigned to this species. They are collected at three localities in a small area in the low parts of the eastern Sila mountains not far from the coast, and at one locality in the Monte Pollino region (M. Manfriana). This material does not belong to D. heterophyla but to D. rikele (Sila mountains) and D. butzele (M. Manfriana), respectively. As no specimens in the Servadei collection belong to D. heterophyla, this species should be deleted from the list of Doratura species in Italy.

Ecology. The species apparently prefers dry lowland sites on the Balkan Peninsula. In Bulgaria, it was collected between 100 and 650 m. Two collection sites in Uzbekistan are at 1000 and 1100 m, respectively.

Phenology. We collected adults from the end of May until the end of August (Bulgaria).
