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.

–0.75. r-m shorter than bM, r-m with 1 seta, bM non-setose.

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.

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
)
