I'm having difficulty keying these. This one seems to have only one "tooth" on the abdominal emargination, but I can't find any good match byond that. Possibly B. peregrinus Herbst, but I'm not sure. Suggestions welcome :)

Dissection needed
These generally need dissection (males) to get to species. I also find the descriptions of the external characters in keys rather difficult to observe. Close-up shots of the visible terminal abdominal segment are also helpful.
