Who recognises this genitalia? From August 2022, on the banks of the Loire at Cour sur Loire, near Blois. It has 3 post-sutural dc, and pre-sutural acrostichals. No marginals on T3. No bristles on the dorsal side of R1.

Does anyone have any thoughts on how I could borrow a copy of Richet, Blackith and Pape Sarcophaga of France, which I assume has a key which would allow me to ID this specimen? I can see from the online catalogue that the Bibliotheque Nationale in Paris has a copy, but it looks like you have to consult it on site, which isn't much good to me.

Looks like S. melanura to me. From Pape 1987: "Male. Frons very broad, 0.26-0.29 x head-width. Thorax with 3 post dc. Legs:mid femur with a complete row of av bristles and an apical row of short pv bristles. Hind trochanter ventro-medially with setae of medium length and a long bristly apical seta. Hind tibia with long hairs on pv and v surfaces.Abdominal T3 without median marginal bristles. Terminalia black. Protandrial segment non-pollinose, or with only traces of pollinosity, and with marginal bristles. Aedeagus with triangular vesical lobes. Harpes reduced to a pair of small forked lobes pointing laterally. Styli rather large and widely separated by the median sclerotisation. Juxta small and weakly sclerotised, almost covering the styli in dried specimens (Fig 253) , but often raised in glycerol preparations (Fig 252)." You could also try the British key and see if it runs to melanura with that: https://osf.io/vf5r6 tristram attached the following image:  [80.9Kb] |

Thanks so much Tristram. I had previously run it through the British key and decided it wasn't matching anything at the end. I'll try it again. S. melanura is quite likely in that I have already recorded that species from that site. So maybe it's just a matter of looking more carefully at this specimen.
