Berlin - September, 2019 - 3.8 mm

Hello everyone,

I think that this species is Periscepsia carbonaria. I definitely see upright bristles on the scutellum. I originally thought that it was a Rhinophoridae but the antennae don't match.

Best wishes,
John

The question is not whether there are bristles present on dorsum of scutellum, but how many. I cannot tell. That said, the discal bristles are lacking, which settles it as Periscepsia carbonaria. A species well known to be active into October

Thank you, Theo. I can only see one upright bristle in my lateral photos. I'd need to look at the specimen under the microscope to see clearly. It was found hanging out with Coenosia atra on a stonewall by a pond. I can always add a lateral photo if you wish to see more.

Best wishes,
John

adding a lateral shot for closure.
