From Korneyev :
Diagnosis: This species is similar to O. porcus in having microtrichose areas on abdominal tergites 3 and 4 laterally reaching tergite margins, but clearly differs from it by having occiput, femora and tibiae entirely black (widely orange-yellow in O. porcus). It also clearly differs from O. ornata by the microtrichose areas on abdominal tergites 3 and 4 laterally reaching tergite margins, and medial and lateral surstyli of male robust and widely fused (see Kameneva, 1997 (as “O. formosa”) (in O. ornata, microtrichose areas on abdominal tergites 3 and 4 short, not reaching lateral margins, surstyli narrow and separated) !
So NO, it’s not O. ruficeps !
