Tschirnhaus, 3 ♂♂ , PWMP . Redescription (male) HEAD. Dark brown, antenna unicolorous pale brown; maxillary palpus very pale brown. Eye bridge 2–3 facets wide. Face with 10–12 scattered longer and shorter setae. Clypeus with 1–4 setae. Maxillary palpus with 3 segments; segment 3 longer than segment 1, segment 2 shortest; segment 1 with 3–4 setae, with dorsal pit of sensilla; antennal flagellomeres with slightly rough surface, body of flagellomere 4 2.15–2.4× as long as wide, neck shorter than broad, longest setae longer than width of flagellomere. THORAX. Dark brown, setae pale. Anterior pronotum with 6–12 setae. Episternum 1 with 13–15 setae. Scutum with long dorsocentrals, with some longer and shorter laterals, scutellum with 2 longer and some short setae. WING. Fumose. Length 1.8–1.9 mm . Width/length 0.40. Veins distinct. R1/R 0.65. c/ w 0.70 –0.75. r-m shorter than bM, r-m with 1 seta, bM non-setose. LEGS. Pale brown. Coxal setae pale. Front tibial organ with pale vestiture forming a row. Front tibial spur longer than tibial width. Claws without teeth. ABDOMEN. Pale brown, setae pale. HYPOPYGIUM ( Fig. 1 A–D). Brown, concolorous with abdomen. GONOCOXA. Narrow, longer than gonostylus, mesial margin with normal setosity. GONOSTYLUS. Narrow, rather straight, slightly thickened at middle, slightly narrowed towards apex, with mesial side not impressed; with dense apical setosity, without apical tooth, with 8–9 apical-subapical megasetae; megasetae subequal in size, slightly curved and sharp. Tegmen conical, apically truncate, with straight lateral sides, with indistinct basolateral corners, laterally sclerotized, with area of aedeagal teeth. Aedeagal apodeme long. Remarks Bradysia ascenda was described on the basis of three males from the Austrian Alps ( Rudzinski 1994 ). In having its setae pale and in having a distinct sensory pit in the maxillary palpus, it belongs to the Bradysia tilicola group of Menzel & Mohrig ( 2000 ) .
