Diagnosis. Dasypogon diabolicus sp. nov. is distinguished from other Central European species D. diadema by the characters presented in the key (Fig. 1) and by the male and female terminalia (Figs 2, 3). From D. octonotatus and D. kugleri, with which it may come into contact in the east and south of its range, it differs mostly in the genital structures, e.g. D. kugleri has a shorter median lobe and broader lateral lobes (see Theodor 1980), while the lateral lobes of D. octonotatus are differently shaped and not bent towards the ventral side (see Weinberg 1975). However, Dasypogon diabolicus sp. nov. is most similar to other Balkan species in its aedeagus morphology (Szczepański in prep.).
Description. Measurements. Body length 16–22 mm; body width 3.3–4.9 mm. Morphology. As D. diadema but with the following differences. Thorax. Female. Coloration of thoracic macrosetae (except scutellar ones which are always black) and short setae variable, usually yellowish-brown, sometimes with admixture of black macrosetae and setae. Wings: Male. apex of wings more transparent. Abdomen: Male. Whitish tomentum in the lateral posterior part of tergites constant, usually well visible on tergites 1–5, exceptionally week whitish tomentum in the lateral posterior part of sternites 2–4. Female. Seta coloration variable, often white or yellow, sternites 1–4 with whitish tomentum in the lateral posterior part, brick-red spots on tergites 3–6, presence of spots and their shape variable, more distinct only on tergites 4–5, on tergite 3 spot usually limited to posterior margin or absent, similarly on tergite 6, where spot usually limited to anterior part. Male terminalia. (Fig. 2C, D) Terminalia rotated, mostly black with pilosity of variable length, epandrium divided into two similar halves, with heart-shaped apical side, only apically with short yellow-brown setae, hypandrium rounded apically, with angular concave posterior margin, tuft of long thick setae medially, and sparse, evenly distributed shorter setae, gonocoxite (basistylus) relatively large, rounded outwards, tapering anteriorly with clearly separate rounded apex, inner margin undulating, with rounded tooth consisting of two parts bent at different angles, a group of short brown setae protruding from under the tooth, gonocoxite appendage brownish, broad, tapering in apical part, sharp hook-like apex, gonostylus (dististylus) brownish, in the form of slender, elongated, curved appendage, with tip bent downwards, bearing several sparse short brown setae, mostly in middle part, shape of gonopods vary depending on the angle of view, aedeagus massive, with three lobes, median lobe short, with ventral serrated excrescence in the middle, lateral lobes long, tapering apically, hook-shaped, bent towards the ventral side, inwardly pointing apex, lateral projections between the median and lateral lobes indistinct, ejaculatory apodeme more elongate. Female genitalia. (Fig. 3B, D, F) Tergite 8 laterally with two poorly chitinized areas, sternite 8 (hypogynium) membranous apically, membranous part more or less rounded, each acanthophorite composed of a group of six spines, furca as in fig. 3, three spermathecae, spermathecal duct shorter, extended to middle of abdominal segment 3.
Etymology. The specific name is derived from the Latin diabolicus (= diabolical), and refers to the vernacular Polish name for representatives of the genus Dasypogon. The name “czarny diabeł” (black devil) was first used by Bogusław Soszyński and thereafter taken up by the entomological community. This is a tribute to the great dipterologist—Bogusław Soszyński—a mentor to many young entomologists in Poland (Szadziewski & Żóralski 2018).
Distribution. The species is distributed in the Pannonian Basin as far north as Moravia; also known from single localities in south-eastern Poland and western Ukraine. So far recorded from eastern Austria, eastern Czech Republic, Hungary, Moldova, Slovakia, southern Poland and western Ukraine (Fig. 4). However, it is likely that the species can also be found in Romania.
