Abdomen und p rotgelb, 6 Schildchenborsten ... myiopiformis Rob.-Desv. — Abdomen und p schwarzgrau, 4 Schildchenborsten ... cuniculorum Rob.-Desv. So it keys to Orbellia myiopiformis. The description says "Schulterbeulen rotgelb", "humeri reddish yellow", which I don't see. I have observed in Dolichopus that humeri can appear yellowish under a microscope but black to a camera. Edit: But nivicola is not in that key, so you need better literature. It was considered a synonym of O. myiopiformis. Edited by John Carr on 18-12-2023 20:35
