basirufus? - Pseudomasaris basirufus - male

basirufus? - Pseudomasaris basirufus - Male
Black Mountain, 1,400 ft. elevation, Imperial County, California, USA
May 5, 1973
I'm fairly confident in the species ID, but still hoping for a confirming opinion. Specimen collected by P. H. Sullivan.

Moved from Pseudomasaris.

Hi Eric,
I agree that this is a basirufus male. The similar P. maculifrons has a central white spot on the frons. In your wasp the frons appears to be black. I assume that you still have access to this specimen, or have a frontal photo?
Also, antennae are as in basirufus, not maculifrons. Extent of red areas varies considerably in both spp.
I hope to observe, and photograph some live ones soon!
