Note on identity. The male holotype of Hylemyia judicariae Pokorny deposited in the Hungarian Museum of Natural History, Budapest, came from Condino, a locality in Italy: Trentino-Alto Adige/Südtirol. It was examined by Hennig (1974, plate-fig. 1165) and treated as a junior synonym of Delia flavifrons (Zetterstedt) [now = D. pruinosa (Zetterstedt)], but Hennig’s illustration of the male hypopygium shows clearly that Pokorny’s species is in fact a valid species within the D. pruinosa species group.

Description. The adults differ from other species of the Delia pruinosa species group as follows: Male & female. Differs from D. pruinosa in having hind tibia with apical av-seta normally developed (Fig. 6, arrow).

Male. Sternite IV no wider than sternite V and sternites III–V with lateral setae shorter than in D. pruinosa (Figs. 17, 18); surstyli moderately broad but strongly tapering in caudal aspect (Fig. 19); distiphallus, as also in D. capdellae sp. nov. (Fig. 40), with paraphallic processes longer than postero-median extension (Fig. 22).

Female. Oviscapt (Figs. 24, 25) rather thick, decidedly longer than preabdomen when fully extended; hypoproct much longer than broad, without cuticular pubescence; cerci with several apical setae of moderate and equal strength. Oviscapt overall very similar to that of D. sileni sp. nov. (Figs. 32, 33), but distinguished by having the basal membranes of segments VII and VIII covered in scales with a dark, proclinate spicule (Fig. 25).
