Type locality
“Der Hartz, Oesterreich” [sic][Austria].
Type material studied
Lectotype, ♂, pinned, in MNB, here designated to fix the concept of Cheilosia hercyniae Loew and to ensure the universal and consistent interpretion of the same. The original description concerns only the male sex. The lectotype is labelled: ‘Austria, Schiner’, ‘Coll. H. Loew’, ‘Zool. Mus., Berlin’, ‘Lectotype Cheilosia hercyniae Loew, Ståhls & Barkalov des.’.
Description
♂: Face in frontal view moderately divergent from level of antennal insertion to lower mouth edge, with slight to moderate pollinosity, but facial knob shining. Facial knob moderately protruding (Fig. 8A). Parafacia rather broad, approximately 2/3 of width of basoflagellomere, with slight pollinosity in upper part and shining in lower part and with short white pile. Frons moderately swollen, shining, with black pile. Frontal angle slightly > 90°. Lunula reddish brown. Antennal pits separated. Vertical triangle with black pile. Eye-contiguity nearly equal to the length of frons without lunula. First and second antennal segment dark-brown, third segment somewhat quadratic, bright orange with dorsal margin black (Figs 8B, 12C). Arista pubescent, with very short pile. Scutum shining (bluish ting), finely punctated, with whitish to yellowish erect, rather long, pile of about even length, intermixed with black pile of same length or slightly longer, also on scutellum, margin with 8–10 longer black bristles. Postalar callus with 3–5 bristles. Anepisternum and katepisternum shining, with slight pollinosity, and with whitish and black, rather long, pile intermixed. Katepisternum with dorsal and ventral hair patches broadly divided. Wing brownish. Wing completely microtrichose. R4 + 5 of wing not curved. Halter yellow, knob dark-brown. Legs with distal part of femora, tibia with basal 1/3–1/2 and distally narrowly yellow, tarsi dorsally dark-brown. Mesofemur posteriorly with long yellow pile and with some black ones on the tip; metafemur ventrally with short black (rather strong) pile, distally dorsally with longer black and yellow pile, its anterior surface with long yellow pile in basal 2/3 and with black pile in apical 1/3. Abdomen slightly oval, shining tergites I–III with brownish pollinosity medially, tergite IV with stripe of pollinosity antero-medially. Pile yellow, erect on all tergites, tergite IV on postero-lateral corners also with black pile. Pregenital segments with pollinosity, with yellow pile. Sternites pollinose with yellow erect pile, sternite IV also with short appressed black pile medially. Hypopygium as on Fig. 8E–F. ♀: Face and parafacia as in male. Basoflagellomere big, bright orange-yellow, quadratic, with a long (≈ 1/3 of the length of antenna) groove on the inner ventral side (Fig. 8C). Anterior 1/3 of frons very shiny, with fine punctation, and very short pile, posterior 2/3 shining, coarsely punctated, with short yellow and longer black erect pile (Fig. 8D). Scutum shining, rather coarsely punctated, with short erect yellow and slightly longer black pile. Scutellum margin with 4–6 rather strong black bristles. Legs as in the male. Wing yellowish. Abdomen oval, shining, densely punctated, tergite I and antero-medial part of tergite II with pollinosity. Pile erect, yellow on lateral parts, long on lateral part of tergite II, and short, black, appressed pile medially. Sternites with slight pollinosity. Otherwise as the male.
Size. Body length 8–11 mm.
