Psyrassa - Psyrassa pertenuis

Psyrassa - Psyrassa pertenuis
Rockville, Montgomery County, Maryland, USA
June 9, 2021
Size: body 11.5mm
This one has a spine on the 3rd antennal segment which I think makes it Psyrassa pertenuis rather than P. unicolor.

TIA

thanks to both of you

I would call this P. pertenui
I would call this P. pertenuis based on the fairly long spine on antennomere 3 and the elongate setae at the base of the elytra.

antennal spine
is that spine not substantial enough for Psyrassa pertenuis? I had some doubts about it. TIA

thanks for checking
but I think you've got the right ID. Besides, if you need "guidance and adult supervision" for beetle IDs where does that leave the rest of us? :-)
